  Description 
  of 
  Nevj 
  Species 
  of 
  Helinai. 
  

  

  This 
  species 
  is 
  closely 
  allied 
  to 
  the 
  Arkansas 
  Flycatcher; 
  

   (T. 
  verticalis,) 
  and 
  resembles 
  it 
  both 
  in 
  size 
  and 
  the 
  general 
  

   distribution 
  of 
  colors, 
  but 
  is 
  of 
  a 
  darlrer 
  color 
  on 
  the 
  head 
  and 
  

   breast, 
  and 
  has 
  a 
  much 
  larger 
  and 
  stronger 
  bill- 
  The 
  T. 
  ver- 
  

   ticalis 
  also 
  differs 
  in 
  having 
  the 
  tail 
  somewhat 
  forked, 
  and 
  the 
  

   outer 
  webs 
  of 
  the 
  lateral 
  feathers 
  yellowish 
  white, 
  

  

  I 
  have 
  named 
  it 
  in 
  honor 
  of 
  Mr. 
  John 
  Cassin, 
  of 
  Philadel- 
  

   phia, 
  whose 
  devotion 
  to 
  the 
  science 
  of 
  Ornithology 
  is 
  well 
  

   known.
