Calichelidon cyaneoviridis {Bryant). Bahaman Swallow.* 



No. S677, $ ad., Coll. of W. E. D. S., Garden Key, Dry Tor- 

 tugas, Florida, April 7, 1S90. 



As the known habitat of the Cuban Cliff Swallow is Central 

 America, from northern Yucatan to Panama, Cuba, San Do- 

 mingo, Jamaica and Porto Rico, it is not surprising that it should 

 occur at the Tortugas, especially in the spring. It seems probable 

 that this species will be found to occur more or less regularly at 

 this point during March and early April. The Bahaman 

 Swallow must, however, be regarded, in the light of present evi- 

 dence, as an accidental visitor, its known habitat being the 

 Bahamas where it has been regarded by collectors as a rare 

 species.

[6. Thryophilus sp. /'There is a single specimen of a Wren of 



the T. Icucotis type in Mr. Riker's collection, collected by Williams and 

 labelled by him, "Corresponding to nest, $ ." The date and locality, 

 farther than "Amazon," have been omitted, but there is little doubt that 

 the bird came from Santarem, as the skin is evidently of Mr. Williams's 

 make. With the material at my command I cannot satisfactorily identify 

 this bird with any of the described forms, but rather than add to the con- 

 fusion which already exists in this puzzling group I prefer to leave it 

 unnamed. In general coloration it agrees exactly with a specimen of 

 superciliaris (Lawr.) from Puna Island, but has the bill shorter, the 

 supecciliaries much more restricted, and the ear-coverts and cheeks dis- 

 tinctly margined with the color of the back. 



True T. Icucotis (Lafr.) I have never seen; this bird may possiblv be 

 that species ; it does not, however, agree with descriptions, and is quite
