Item 3.  Incorporation of Documents by Reference.

     The following  documents filed by The Jones Financial  Companies,  L.L.L.P.
("JFC") with the Securities and Exchange Commission (the "Commission") under the
Securities   Exchange  Act  of  1934,  as  amended  (the  "Exchange   Act")  are
incorporated herein by reference:

         1. JFC's Annual Report on Form 10-K for its fiscal year ended  December
31, 1997 (filed under JFC's  former name The Jones  Financial  Companies,  L.P.,
LLP).

         2. JFC's Current Report on Form 8-K filed on March 12, 1998.

         3. The description of the limited  partnership  interests in JFC, which
is  contained  in JFC's  Registration  Statement  on Form 8-A  filed  under  the
Exchange Act, including any amendment or report updating such description.

     All documents  subsequently filed by JFC pursuant to Sections 13(a), 13(c),
14 and  15(d) of the  Exchange  Act  (prior to the  filing  of a  post-effective
amendment  which  indicates that all securities  offered have been sold or which
deregisters  all  securities  then  remaining  unsold)  shall  be  deemed  to be
incorporated by reference herein and to be a part hereof from the date of filing
of such documents.

     Any statement contained herein or in a document incorporated,  or deemed to
be  incorporated,  by  reference  herein,  shall be  deemed  to be  modified  or
superseded for purposes hereof to the extent that a statement  contained  herein
or in  any  other  subsequently  filed  document  modifies  or  supersedes  such
statement.  Any such  statement so modified or  superseded  shall not be deemed,
except as so modified or superseded, to constitute a part hereof.

Item 4.  Description of Securities.

     Not Applicable.

Item 5.  Interest of Named Experts and Counsel.

     Neither the named experts or counsel  referenced  below have an interest in
JFC.

                                       2
<PAGE>

     The financial  statements  incorporated  by reference in this  Registration
Statement  have  been  audited  by  Arthur  Andersen  LLP,   independent  public
accountants, as indicated in their report with respect thereto, and are included
herein in  reliance  upon the  authority  of said firm as experts in giving said
reports.

     The  legality  of the  limited  partnership  interests  in JFC to be issued
pursuant to the terms of the 1998 Employee Limited Partnership Interest Purchase
Plan  of JFC  will be  passed  upon  for JFC by  Bryan  Cave  LLP of St.  Louis,
Missouri.

Item 6.  Indemnification of Directors and Officers.

     The  partnership  agreement  of JFC,  as  amended  from  time to time  (the
"Partnership  Agreement") provides that neither the Managing Partner (as defined
in the Partnership  Agreement) nor any of the general partners will be liable to
any of the partners  for any acts or  omissions  made in good faith on behalf of
JFC and in a manner  reasonably  believed  by him to be within  the scope of his
authority and in the best interests of JFC, provided such partner was not guilty
of gross negligence or gross  misconduct.  JFC also is required to indemnify the
Managing Partner and the general partners against any loss or damage incurred by
any such  partner by reason of any action  performed  or  omission  made in good
faith by any of them on behalf  of JFC and in a manner  reasonably  believed  by
such partner to be within the scope of his authority or in  furtherance of JFC's
interest, other than actions for which such partner would be liable as described
above. As a result of these  provisions,  the limited  partners of JFC will have
more  limited  rights  against  such  persons  than they would  have  absent the
limitations  in the  Partnership  Agreement.  Indemnification  of  the  Managing
Partner  and  the  general  partners  would  deplete  JFC  assets  unless  JFC's
indemnification  obligation  is covered by  insurance.  While JFC may attempt to
purchase liability insurance to provide for its indemnification obligation, such
insurance may not be available at a reasonable price or at all.

Item 7.  Exemption from Registration Claimed.

         Not Applicable.

Item 8.  Exhibits.

         The  following  documents  are  filed  as a part of  this  Registration

Item 9. Undertakings

     (a) The undersigned registrant hereby undertakes:

          (i) To file,  during  any  period  in which  offers or sales are being
     made, a post-effective amendment to this registration statement:

               (A) To include any prospectus required by section 10(a)(3) of the
          Securities Act of 1933;

               (B) To  reflect  in the  prospectus  any facts or events  arising
          after the effective  date of the  registration  statement (or the most
          recent post-effective amendment thereof) which, individually or in the
          aggregate, represent a fundamental change in the information set forth
          in the  registration  statement.  Notwithstanding  the foregoing,  any
          increase  or decrease  in volume of  securities  offered (if the total
          dollar  value of  securities  offered  would not exceed that which was
          registered)  and  any  deviation  from  the  low  or  high  end of the
          estimated  maximum  offering  range  may be  reflected  in the form of
          prospectus  filed with the  Commission  pursuant to Rule 424(b) if, in
          the aggregate,  the changes in volume and price represent no more than
          20 percent change in the maximum aggregate offering price set forth in
          the   "Calculation  of  Registration   Fee"  table  in  the  effective
          registration statement.

               (C) To include any material  information with respect to the plan
          of distribution not previously disclosed in the registration statement
          or any  material  change  to  such  information  in  the  registration
          statement;

     Provided,  however, that paragraphs (a)(i)(A) and (a)(i)(B) do not apply if
the  registration  statement  is on Form  S-3,  Form  S-8 or Form  F-3,  and the
information  required  to be  included in a  post-effective  amendment  by those
paragraphs  is  contained  in periodic  reports  filed with or  furnished to the
Commission by the  registrant  pursuant to Section 13 or 15(d) of the Securities
Exchange Act of 1934 that are  incorporated  by  reference  in the  registration
statement.

          (ii) That,  for the purpose of  determining  any  liability  under the
     Securities Act of 1933, each such post-effective  amendment shall be deemed
     to be a new  registration  statement  relating  to the  securities  offered
     therein,  and the offering of such  securities at that time shall be deemed
     to be the initial bona fide offering thereof.

          (iii)  To  remove  from  registration  by  means  of a  post-effective
     amendment any of the securities being registered which remain unsold at the
     termination of the offering.

     (b) The  undersigned  registrant  hereby  undertakes  that, for purposes of
determining  any liability  under the Securities Act of 1933, each filing of the
registrant's  annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable,  each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the  registration  statement shall be
deemed to be a new  registration  statement  relating to the securities  offered
therein,  and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

                                       4

     (c) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors,  officers and controlling  persons of
the  registrant  pursuant  to  the  foregoing  provisions,   or  otherwise,  the
registrant  has been advised that in the opinion of the  Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore,  unenforceable. In the event that a claim for indemnification
against such  liabilities  (other than the payment by the registrant of expenses
incurred or paid by a director,  officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director,  officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

Item 3.  Incorporation of Documents by Reference.

     The following  documents filed by The Jones Financial  Companies,  L.L.L.P.
("JFC") with the Securities and Exchange Commission (the "Commission") under the
Securities   Exchange  Act  of  1934,  as  amended  (the  "Exchange   Act")  are
incorporated herein by reference:

         1. JFC's Annual Report on Form 10-K for its fiscal year ended  December
31, 1997 (filed under JFC's  former name The Jones  Financial  Companies,  L.P.,
LLP).

         2. JFC's Current Report on Form 8-K filed on March 12, 1998.

         3. The description of the limited  partnership  interests in JFC, which
is  contained  in JFC's  Registration  Statement  on Form 8-A  filed  under  the
Exchange Act, including any amendment or report updating such description.

     All documents  subsequently filed by JFC pursuant to Sections 13(a), 13(c),
14 and  15(d) of the  Exchange  Act  (prior to the  filing  of a  post-effective
amendment  which  indicates that all securities  offered have been sold or which
deregisters  all  securities  then  remaining  unsold)  shall  be  deemed  to be
incorporated by reference herein and to be a part hereof from the date of filing
of such documents.

     Any statement contained herein or in a document incorporated,  or deemed to
be  incorporated,  by  reference  herein,  shall be  deemed  to be  modified  or
superseded for purposes hereof to the extent that a statement  contained  herein
or in  any  other  subsequently  filed  document  modifies  or  supersedes  such
statement.  Any such  statement so modified or  superseded  shall not be deemed,
except as so modified or superseded, to constitute a part hereof.

Item 4.  Description of Securities.

     Not Applicable.

Item 5.  Interest of Named Experts and Counsel.

     Neither the named experts or counsel  referenced  below have an interest in
JFC.

                                       2
The financial  statements  incorporated  by reference in this  Registration
Statement  have  been  audited  by  Arthur  Andersen  LLP,   independent  public
accountants, as indicated in their report with respect thereto, and are included
herein in  reliance  upon the  authority  of said firm as experts in giving said
reports.

     The  legality  of the  limited  partnership  interests  in JFC to be issued
pursuant to the terms of the 1998 Employee Limited Partnership Interest Purchase
Plan  of JFC  will be  passed  upon  for JFC by  Bryan  Cave  LLP of St.  Louis,
Missouri.

Item 6.  Indemnification of Directors and Officers.

     The  partnership  agreement  of JFC,  as  amended  from  time to time  (the
"Partnership  Agreement") provides that neither the Managing Partner (as defined
in the Partnership  Agreement) nor any of the general partners will be liable to
any of the partners  for any acts or  omissions  made in good faith on behalf of
JFC and in a manner  reasonably  believed  by him to be within  the scope of his
authority and in the best interests of JFC, provided such partner was not guilty
of gross negligence or gross  misconduct.  JFC also is required to indemnify the
Managing Partner and the general partners against any loss or damage incurred by
any such  partner by reason of any action  performed  or  omission  made in good
faith by any of them on behalf  of JFC and in a manner  reasonably  believed  by
such partner to be within the scope of his authority or in  furtherance of JFC's
interest, other than actions for which such partner would be liable as described
above. As a result of these  provisions,  the limited  partners of JFC will have
more  limited  rights  against  such  persons  than they would  have  absent the
limitations  in the  Partnership  Agreement.  Indemnification  of  the  Managing
Partner  and  the  general  partners  would  deplete  JFC  assets  unless  JFC's
indemnification  obligation  is covered by  insurance.  While JFC may attempt to
purchase liability insurance to provide for its indemnification obligation, such
insurance may not be available at a reasonable price or at all.

Item 7.  Exemption from Registration Claimed.

         Not Applicable.

Item 8.  Exhibits.

Item 9. Undertakings

     (a) The undersigned registrant hereby undertakes:

          (i) To file,  during  any  period  in which  offers or sales are being
     made, a post-effective amendment to this registration statement:

               (A) To include any prospectus required by section 10(a)(3) of the
          Securities Act of 1933;

               (B) To  reflect  in the  prospectus  any facts or events  arising
          after the effective  date of the  registration  statement (or the most
          recent post-effective amendment thereof) which, individually or in the
          aggregate, represent a fundamental change in the information set forth
          in the  registration  statement.  Notwithstanding  the foregoing,  any
          increase  or decrease  in volume of  securities  offered (if the total
          dollar  value of  securities  offered  would not exceed that which was
          registered)  and  any  deviation  from  the  low  or  high  end of the
          estimated  maximum  offering  range  may be  reflected  in the form of
          prospectus  filed with the  Commission  pursuant to Rule 424(b) if, in
          the aggregate,  the changes in volume and price represent no more than
          20 percent change in the maximum aggregate offering price set forth in
          the   "Calculation  of  Registration   Fee"  table  in  the  effective
          registration statement.

               (C) To include any material  information with respect to the plan
          of distribution not previously disclosed in the registration statement
          or any  material  change  to  such  information  in  the  registration
          statement;

     Provided,  however, that paragraphs (a)(i)(A) and (a)(i)(B) do not apply if
the  registration  statement  is on Form  S-3,  Form  S-8 or Form  F-3,  and the
information  required  to be  included in a  post-effective  amendment  by those
paragraphs  is  contained  in periodic  reports  filed with or  furnished to the
Commission by the  registrant  pursuant to Section 13 or 15(d) of the Securities
Exchange Act of 1934 that are  incorporated  by  reference  in the  registration
statement.

          (ii) That,  for the purpose of  determining  any  liability  under the
     Securities Act of 1933, each such post-effective  amendment shall be deemed
     to be a new  registration  statement  relating  to the  securities  offered
     therein,  and the offering of such  securities at that time shall be deemed
     to be the initial bona fide offering thereof.

          (iii)  To  remove  from  registration  by  means  of a  post-effective
     amendment any of the securities being registered which remain unsold at the
     termination of the offering.

     (b) The  undersigned  registrant  hereby  undertakes  that, for purposes of
determining  any liability  under the Securities Act of 1933, each filing of the
registrant's  annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable,  each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the  registration  statement shall be
deemed to be a new  registration  statement  relating to the securities  offered
therein,  and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

                                       4
(c) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors,  officers and controlling  persons of
the  registrant  pursuant  to  the  foregoing  provisions,   or  otherwise,  the
registrant  has been advised that in the opinion of the  Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore,  unenforceable. In the event that a claim for indemnification
against such  liabilities  (other than the payment by the registrant of expenses
incurred or paid by a director,  officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director,  officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
