band of the same colour extending acrossr the throat, hut the 

 top of the head, which is almost devoid of a crest, and the 

 neck are broivn, like the hack, instead of dark slate-grey ; and 

 the white tips to the feathers of the breast and belly are 

 almost entirely absent, or only faintly indicated along the 

 middle line of the underparts. Total length 10'5 inches, 

 culraen 1'15, wing 4*85, tail 4"65, tarsus 0'85. 

 Habitat. Fuga Island, Babuyan Group. 

 Since vol. vi. of the ' Catalogue of Birds ' appeared in 1881 

 two examples of a Hypsipetes from the island of Chusan have 

 been added to the national collection. 



Dr. Stejneger (P. U.S. Nat. Mus. ix. p. 643, 1886), after 

 describing H. pryeri, goes on to say, "a specimen from 

 Chusan, China (U. S. Nat. Mus. no. 85685), acquired by 

 Mr. Jouy at the Shanghai Museum, differs in no essential 

 from the typical Japanese H. amaurotis." 



Though the two British Museum specimens from Chusan 

 at first sight seem rather different from Japanese examples 

 of H. amaurotis, I am satisfied that this is partly due to the 

 somewhat soiled condition of the underparts in both. There 

 is a distinct indication of the reddish-brown collar across the 

 throat, hut this is often nearly as much developed in typical 

 birds from Japan. There seems to be no doubt that H. amau- 

 rotis is partly migratory, as the species is recorded as found 

 during the winter months in Korea, and we have examined 

 examples from Chusan, Ningpo, and the Loo Choo Islands ; 

 but H. squamiceps, H. pryeri, and H. fugensis are appa- 

 rently resident forms which do not migrate. Although 

 H. squamiceps and H. pryeri closely resemble one another in 

 plumage, they are perfectly distinct, the Bonin bird being 

 not only much larger, but having the bill and, as Dr. Stej- 

 neger points out, the tarsus longer in proportion. In all 

 these species the males are, on the whole, distinctly larger 

 than the females, a point which is not apparent from the 

 wing-measurements given by Mr. Seebohm. He kindly 

 allowed me to look over his fine collection of Hypsipetes, 

 and these, added to the British Museum specimens, make 

 an exceptionally fine and complete series from the Bonin
