  Specimens 
  of 
  this 
  Southern 
  and 
  Western 
  form 
  of 
  G.

  havei 
  

   been 
  received 
  through 
  Professor

  from

  and 
  Camden, 
  

   Arkansas, 
  and

  There 
  are 
  specimens 
  in 
  the 
  

   United 
  States 
  iSTational 
  Museum 
  from 
  Corpus 
  Christi, 
  Texas, 
  and 
  from 
  

   Portage 
  Eiver, 
  at 
  Oak 
  Harbor, 
  Ohio. 
  Mr. 
  W. 
  P. 
  HayMias 
  recorded 
  

   this 
  form 
  from 
  the 
  following 
  new 
  localities 
  in 
  Indiana: 
  Turkey 
  Lake, 
  

   Kosciusko 
  County; 
  Lake 
  Maxinkuckee, 
  Marshall 
  County; 
  Kankakee 
  

   Eiver, 
  Lake 
  County; 
  Terre 
  Haute, 
  Vigo 
  County. 
  

  

  Specimens 
  procured 
  by 
  Professor 
  Meek 
  at 
  McAlister, 
  Indian 
  Terri- 
  

   tory, 
  are 
  peculiar. 
  The 
  rostrum 
  is 
  narrower, 
  more 
  deeply 
  excavated, 
  

   with 
  more 
  convergent 
  sides 
  than 
  in 
  typical 
  specimens 
  of 
  C. 
  h. 
  acutus. 
  

   The 
  rostral 
  acumen, 
  too, 
  is 
  longer, 
  surpassing 
  the 
  antenuular 
  peduncle, 
  

   the 
  lateral 
  spines 
  more 
  prominent. 
  The 
  rostrum 
  approaches 
  the 
  form 
  

   seen 
  in 
  the 
  Eastern 
  G. 
  hlandingii, 
  or 
  even 
  more 
  nearly 
  that 
  of 
  the 
  typ- 
  

   ical

  from 
  Texas.
