Family PHALACROCORACIDAE 



COaMORANTS 

 1. PHALACROCORAX CARBO SINENSIS (Shaw and Nodder) 



Pelecanus sinensis Shaw and Nodder, Nat. Miscel., vol. 13, 1802, p. 52& (China). 



One adult male, 157 miles west-northwest of Paotow, Inner Mon- 

 golia, April 9; 1 immature male and 1 immature female, Choni, 

 Kansu, August 30; 2 immature males, southeast corner of Lake 

 Kokonor, Tibet, August 14. 



In recent years I have been identifying all specimens of this 

 species received by the Museum from China as of this form, but am 

 not convinced that I am correct in doing so. An adult female from 

 Yunnan and an adult female from Amoy are somewhat smaller than 

 adult specimens from western Szechwan. There may be a southern 

 and northern race in China, but the series at my command is too 

 small to determine the matter. The above specimens from Mongolia 

 and Tibet agree fairly well with the Szechwan series. 



The immature male from Choni is a native skin, and there is some 

 doubt as to the correctness of the locality.
