  from 
  Lake

  The 
  following 
  is 
  a 
  translation 
  

   of 
  Valenciennes' 
  account: 
  We 
  have 
  received 
  from 
  Lake 
  Ontario 
  a 
  Thymallus 
  very 
  

   near 
  to 
  that 
  of 
  the 
  lake 
  of 
  Geneva. 
  It 
  has, 
  however, 
  more 
  naked 
  space 
  under 
  tbo 
  

   throat, 
  although 
  less 
  than 
  in 
  Thymallus 
  gymnothorax. 
  The 
  head 
  is 
  evidently 
  more 
  

   pointed, 
  the 
  body 
  more 
  elongate, 
  the 
  dorsal 
  a 
  little 
  longer. 
  The 
  denticulations 
  of 
  tbo 
  

   scales 
  are 
  more 
  pronounced. 
  The 
  colors 
  seem 
  scarcely 
  to 
  differ 
  from 
  those 
  of 
  Thymal- 
  

   lus, 
  for 
  our 
  specimens 
  are 
  greenish, 
  with 
  a 
  dozen 
  gray 
  lines 
  aloug 
  tbo 
  flanks. 
  The 
  

   dorsal 
  has 
  4 
  or 
  5 
  longitudinal 
  streaks 
  of 
  red. 
  Our 
  specimens 
  are 
  a 
  foot 
  long 
  ; 
  tbey 
  

   have 
  been 
  sent 
  by 
  M. 
  Milbert.

  The 
  original 
  diagnosis 
  of 
  Stenodus 
  is 
  said 
  to 
  be 
  in 
  "Appendix 
  Bach's 
  Voyage. 
  Rcpt. 
  

   N. 
  Am. 
  Zool., 
  1836." 
  

  

  According 
  to 
  Dr. 
  Bean, 
  our 
  species 
  is 
  probably 
  not 
  distinct 
  from 
  tho 
  Asiatic 
  species, 
  

   S. 
  leucichthys 
  (Guldenstadt).
