213 STEGANOPODES. 



though he states that it is rarer there than in Kamtschatka. I have 

 only one example^ a female, which has only partially completed its 

 moult into adult plumage, that I can refer to this species. It was 

 collected by Mr. Snow on the Kurile Islands. The crests are well 

 developed, the white plumes on the thighs are appearing, but the 

 wings are in full moult. The forehead is bare of feathers for some 

 distance, and the feathering on the side of the lower mandible runs 

 down in nearly a straight line. 



Its range is said to be confined to the North Pacific, where it is 

 supposed to breed on the coasts of Alaska, Kamtschatka, and the 

 intervening islands. 



197. SULA LEUCOGASTRA. 



(BOOBY GANNET.) 



Pelecanus leucogaster, Boddaert, Tabl. PI. Enl. p. 57 (1783). 



The Booby Gannet or Common Booby has always pale yellow feet. 

 When adult it is brown all over, except the underparts below the 

 breast, which are white. Immature specimens are brown all over, 

 paler on the head, neck, and underparts.

The Booby Gannet breeds on the Bonin Islands (Blakiston and 

 Pryer, Trans. As. SoC. Japan, 1883, p. 102), and a single example 

 was brought from Japan by the Siebold Expedition (Temminck and 

 Schlegel, Fauna Japonica, Aves, p. 131). Captain Eodgers also found 

 it on the Bonin Islands, and brought home an example (with pale 

 yellow feet) from the Eastern Sea, between the Loo-Choo Islands 

 and Formosa, which is recorded under the name of Sula fiber (Cassin, 

 Proc. Acad. Nat. Sc. Philad. 1862, p. 325). I have a skin from Peel 

 Island, and an egg from Long Island in the central Bonin group, 

 both collected by Mr. Hoist (Seebohm, Ibis, 1890, p. 107). There 

 is an example in the Norwich Museum sent by Mr. Ringer from 

 Nagasaki. There is an example from Formosa in the Swinhoe collec- 

 tion, and there can be little doubt that Sula sinicadvena (Swinhoe, Ibis, 

 1865, p. 109), from the coast of China, west of the Loo-Choo Islands, 

 must be referred to this species. It has a very wide range, south- 

 wards to Australia, westwards across the Indian and Atlantic Oceans 

 to the West Indies, and eastwards across the Pacific Ocean.
