bushes, with all stages of young, but I saw no eggs. The 

 young in moult were gaining their white plumage on the 

 head and neck, and a few white feathers were scattered over 

 the body. These birds were very tame, and could in some 

 instances be caught by the hand. 



Fregata aquila (Linn.). 



Fregata aquila Saunders, P. Z. S. 1880, p. 163; Grant, 

 Cat. B. B. M. xxvi. p. 443. 



Four males and six females, immature. 



The Great Frigate-bird is very common on South Trinidad, 

 but was not breeding at the time of our visit. Apparently 

 this species was not noticed by the explorers in the

Fregata ariel (Gould).

 Ibis, 1904, p. 214. 



Bill black, pouch bright brick-red; tarsi and toes black. 



I saw several examples of this species at South Trinidad, 

 but obtained only one, an adult male, which was shot by 

 Mr. Lindsay from the yacht as she lay off the island. 



On January 5th we left South Trinidad and steamed up 

 to Martin Vas Islets, which lie about twenty-six miles away. 

 We did not land there, although, I should say, landing is 

 quite possible. There were very few birds seen, the only 

 one obtained being Sterna fuliginosa. Noddies {Anous 

 stolidus) were comparatively abundant, and I saw one 

 example of Micranous leucocapillus. There appeared to be 

 no Petrels on Martin Vas at all. About midday we left 

 for Tristan da Cunha. 



On January 11th two Albatrosses [Diomedea exulans) were 

 seen as well as a large Petrel, which, after looking at the 

 skins in the British Museum, I have no doubt was (Estrelata 

 incerta. From that day until we sighted Tristan da Cunha
