  1 
  The 
  typo 
  of 
  Pogonichthys 
  (Synunctrimis) 
  argyriosus 
  is 
  a 
  young 
  specimen 
  of 
  Pogonich- 
  

   thys 
  macrolepidotus. 
  

  

  2 
  Tbo 
  chief 
  character 
  in 
  which 
  the 
  single 
  known 
  example 
  of 
  P. 
  rapax 
  differs 
  from 
  /'. 
  

   oregonensis 
  is 
  in 
  the 
  small 
  size 
  of 
  the 
  scales 
  before 
  the 
  dorsal 
  fin, 
  there 
  being 
  49 
  iu 
  /'. 
  

   rapax 
  and 
  about 
  42 
  in 
  P. 
  oregonensis. 
  

  

  ^The 
  character 
  of 
  the 
  imperfection 
  of 
  the 
  lateral 
  line, 
  which 
  alone 
  distinguishes 
  

   Phoxinus 
  from 
  Squalius, 
  as 
  understood 
  in 
  the 
  Synopsis, 
  is 
  of 
  such 
  slight 
  importance 
  

   and 
  subject 
  to 
  such 
  variations 
  that 
  I 
  think 
  best 
  to 
  merge 
  the 
  two 
  groups 
  in 
  one. 
  

   The 
  namo 
  Phoxinus 
  seems 
  to 
  have 
  priority.
