Birds of South Trinidad. 215 



a. S iram. Off South Trinidad, 20° 30' S., 29° 22' W., 

 Sept. 13, 1901. Bill slate-grey; skin of throat dull red; 

 tarsi and feet dull pink; iris dark brown (E. A. TV.). 



Although this specimen is apparently immature, and has 

 no white collar round the hind-neck, it has the throat 

 greyish and the fore-neck and breast white. Hitherto only 

 the large Frigate-bird {Fregata aquila) has been recorded 

 from S. Trinidad (cf. Saunders, P. Z. S. 1880, p. 163, and 

 Ogilvie-Grant, Cat. B. Brit. Mus. xxvi. p. 443), where large 

 numbers were seen on the 20th of August, 1874, by the Earl 

 of Crawford, who found the bird nesting on the island. 

 There is, however, no doubt in my mind that the specimen 

 obtained by Dr. Wilson is referable to the smaller Frigate- 

 bird ; and in this identification I am supported by Mr. Ogilvie- 

 Grant, who says : — ( ' This is undoubtedly a nearly adult 

 female of F. ariel, and is gaining the white collar on the 

 hind-neck." Culmen 32 inches; wing 194; tail 12'0.

a. S ad. S.W. Bay, South Trinidad, 20° 30' S., 29° 

 22' W., Sept. 13, 1901. Bill black; tarsi and feet black ; 

 iris very dark brown (E. A. IV.). 



b-g. (Eggs.) South Trinidad, Sept. 13, 1901. 



This species is easily recognised by its perfectly black 

 tarsus and toes, the middle toe and claw being 1*9 inch in 

 length in the single specimen obtained, which has the 

 general appearance of CE. jamaicensis. but has not the pale 

 rump of that species. 



The single white egg procured measures : — Axis 2*5 in., 

 diam. T85. It is very large for the size of the bird.
