212 STEGANOPODES. 



tliougli lie states tliat it is rarer there tliau in Karatschatka. I liave 

 only one example, a female, Avliieli 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 jdumes on the thighs are ai)i)caring, 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 

 intervcnincr islands. 



197. SULA LEUCOGASTRA. 

 (BOOBY GANNET.) 



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



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

 "When adult it is broAvn all over, exeei)t the underparts below the 

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

 paler on the head, neck, and underparts. 



Figures : Gould, Birds of Australia, vii. j)l. 78. 



The Booby Gannet breeds on the Bonin Islands (Blakiston and 

 Prycr, Trans. As. Soc. Japan, 1882, p. 102), and a single example 

 was brought from Japan by the Siebold Expedition (Teniminck and 

 Schlegel, Fauna Jai)oniea, Aves, p. 131). Ca])tain Bodgers also found 

 it on the Bonin Islands, and brought home an example (with i)ale 

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

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

 Proc. Acad. Nat. Sc. Philad. 1802, 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 (Scebohm, 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 Swinhoc collec- 

 tion, and there can be little doubt that Sula simcadwiia (Swiidioe, Ibis, 

 18G5, 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 Iiulian and Atlantic Oceans 

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