  distinct 
  from 
  that 
  of 
  Richardson, 
  in 
  which 
  the 
  tail 
  and 
  its 
  

   coverts 
  are 
  pearl-grey, 
  the 
  outer 
  feather 
  white 
  exteriorly, 
  and 
  

   the 
  tarsus 
  2 
  lines 
  longer. 
  If 
  this 
  should 
  prove 
  to 
  be 
  a 
  dis- 
  

   tinct 
  species, 
  which 
  is 
  more 
  than 
  probable, 
  we 
  would 
  distin- 
  

   guish 
  it 
  by 
  the 
  name 
  of 
  Sterna 
  Forsteri, 
  from 
  the 
  eminent 
  

   naturalist 
  and 
  voyager 
  who 
  first 
  suggested 
  these 
  distinctions." 
  

   That 
  this 
  is 
  a 
  distinct 
  species 
  from 
  Sterna 
  hirundo 
  Linn., 
  

   I 
  have 
  no 
  hesitation 
  in 
  deciding, 
  and 
  have 
  accordingly 
  

   adopted 
  the 
  name 
  proposed 
  by 
  Nuttall 
  for 
  Dr. 
  Richardson's 
  

   bird. 
  I 
  would, 
  however, 
  state, 
  that 
  as 
  Forster's 
  description 
  

   differs 
  in 
  some 
  particulars 
  from 
  Dr. 
  Richardson's, 
  I 
  think 
  it 
  

   by 
  no 
  means 
  conclusive 
  that 
  they 
  refer 
  to 
  the 
  same 
  species. 
  

  

  8. 
  Sylvia 
  autumnalis 
  Wils. 
  Several 
  writers 
  describe 
  this 
  

   as 
  the 
  young 
  of 
  the 
  Hemlock 
  Warbler, 
  (S. 
  parus 
  "Wils.), 
  a 
  

   specimen 
  of 
  which 
  I 
  have 
  never 
  seen. 
  The 
  S. 
  autumnalis 
  is 
  

   observed 
  in 
  great 
  numbers 
  in 
  the 
  autumn. 
  Wilson 
  met 
  with 
  

   more 
  than 
  a 
  hundred 
  in 
  one 
  afternoon 
  ; 
  and 
  Mr, 
  Nuttall 
  in 
  

   placing 
  it 
  as 
  the 
  young 
  of 
  S. 
  parus, 
  remarks 
  : 
  " 
  Nothing 
  is 
  

   more 
  remarkable 
  than 
  the 
  rarity 
  of 
  the 
  adult 
  and 
  the 
  abun- 
  

   dance 
  of 
  the 
  young 
  birds." 
  

  

  There 
  would 
  seem, 
  therefore, 
  but 
  slight 
  grounds 
  for 
  sup- 
  

   posing 
  it 
  the 
  young 
  of 
  S. 
  parus, 
  which 
  I 
  have 
  never 
  believed 
  

   it 
  to 
  be, 
  but 
  have 
  always 
  considered 
  it 
  the 
  young 
  of 
  quite 
  an 
  

   abundant 
  species, 
  viz., 
  Sylviooola 
  striata 
  ; 
  a 
  comparison 
  with 
  

   the 
  female 
  of 
  this 
  species, 
  I 
  think, 
  will 
  remove 
  all 
  doubt. 
  

  

  9. 
  Toxostoma 
  curvirostris 
  (Swainson.) 
  I 
  have 
  received 
  

   several 
  specimens 
  of 
  this 
  fine 
  Mocking-bird 
  from 
  Texas. 
  In 
  

   the 
  proceedings 
  of 
  the 
  Acad, 
  of 
  Nat. 
  Sci. 
  Vol. 
  iv. 
  p. 
  63, 
  Col. 
  

   Geo, 
  A. 
  McCall 
  describes 
  it 
  and 
  gives 
  an 
  account 
  of 
  its 
  ha- 
  

   bits, 
  from 
  observations 
  made 
  at 
  Matamoras, 
  Mexico. 
  

  

  I 
  consider 
  Pomatorhinus 
  turdinus 
  Temm. 
  and 
  T. 
  vetula 
  

   Wagler, 
  identical 
  with 
  this 
  species.
