The two specimens sent were submitted to Mr. Ridgway for deter- 

 mination : he wrote me as follows: — u The Dominica Tinnunculus is iden- 

 tical with that from St. Thomas. St. Bartholomew, and Porto Rico. It 

 is what I have called 1 sparverius var. dominicensis\ but I find upon 

 further investigation that it should bear the name of antillarum, Gm. — 

 dominicemis being, as I now conclude, the bird which I have called leu- 

 coplirys." Mr. Eidgway also wrote: — "You may mention that I have a 

 male I. sparveroides, in the plumbeous plumage, from South Florida."
