396 bulletin: museum of comparative zoology. 



Museum of Natural History for the loan of a series of specimens of 

 Bvtco borealis; to Messrs. Arthur Harris and M. E. Beall of Monte 

 Cristi and to Messrs. M. A. Peters and Angel Gomez of Sosua for 

 many courtesies during my stay in these places and to the hospitable 

 natives along the coast between Sosua and Cabrera. 



Special thanks are also due to Mr. Outram Bangs and Dr. Thomas 

 Barbour for many helpful suggestions and criticisms. 



Annotated List of Species. 



1. PODILYMBUS PODICEPS ANTILLARUM Bangs. 



Seramagullon. 



The Pied-billed Grebe is apparently a rather rare form on the 

 Island. It was met with but once, — at Laguna Flaca, several miles 

 south of Cabrera, where two were seen on March 10. 



2. CoLYMBUS DOMiNicus DOMiNicus Linne. 



Seramagullon. 



A male, Cabrera, March 11. 



Rather uncommon. The specimen taken at Cabrera was asso- 

 ciated with two or three others of the same species in a small muddy 

 pool less than forty yards across. Three were seen in a lagoon at 

 El Batey on April 5. 



3. Pelecanus occidentaus Linne. 

 Alcatrdz. 



The Brown Pelican seems to be rather uncommon along the north 

 coast, at least during the winter months. I found it at only two 

 localities, Estero Balsa on Manzanillo Bay, February 10 where two 

 or three were seen, and at Margante, March 13 where a single indi- 

 vidual was seen flying a short distance off shore.
