342 Murphy, Birds of Trinidad Islet. [j^y 



Annotated List of Birds. 



1. Numida (meleagris?) Linne. Nothing further has ever been 

 heard of Halley's " Guiney Hens " beyond the fact that he freed a pair on 

 Trinidad in April, 1700. The same lack of history applies to a domestic 

 cock and two hens brought from England by Sir James Clark Ross in 1839, 

 and placed ashore " with a view to add somewhat to the stock of useful 

 creatures." 



2. Puffinus gravis (O'Reilly).? A large white-breasted shearwater, 

 believed to have been of this species, was seen by Nicoll (Three Voyages, 

 p. 61) within half a mile of shore at the islets of Martin Vas, twenty-six 

 miles east of Trinidad, on January 5, 1906. 



Puffinus gravis occurs as a rover all over the tropical and south temperate 

 Atlantic. It has been collected by the writer, during the month of March, 

 due south of Trinidad in latitude 39° S. It has been suggested that the 

 species may breed on the island of Tristan da Cunha or one of its outliers.

Nine specimens of petrels were collected at Trinidad, of which five are 

 referable to the species arminjoniana, three to trinitatis, while the other 

 has been made the type of a new species, chionophara. It is remarkable 

 that no example of the gray-breasted phase of arminjoniana, the phase 

 described by Dr. Sharpe as Mstrelata wilsoni, was either collected or 

 observed during our day about the island. 



These three species of closely related, endemic petrels, are the only 

 Tubinares known from Trinidad, since the record of Mstrelata mollis 

 (Saunders, P. Z. S., I. c.) was based upon an incorrect identification. 



Brabourne and Chubb, 1. c., perhaps following a suggestion made in 

 Rowley's Ornithological Miscellany, have synonymized arminjoniana with 

 Mstrelata alba of Gmelin. In justification of this step the authors allege
