Remarks. — This race is separable from Sauropatis chloris cyane- 

 scens by somewhat greater size ; also, in the male, by the duller, more 

 greenish or brownish (less bluish) upper parts, and more greenish 

 (less bluish) v.-ings; in the female by more greenish (less bluish) 

 wings, and slightly duller, more olivaceous upper surface. From 

 Sauropatis chloris azela., of Engano Island, it is distinguishable by 

 its much larger size; also, in the male, by lighter upper parts and 

 more greenish exposed surface of wing-quills ; and, in the female, by 

 much lighter upper surface, and more greenish (less bluish) exposed 

 surface of wing-quills. It differs from Sauropatis chloris davisoni 

 in its decidedly larger size; the male is also lighter, rather more 

 greenish (less bluish) above, the exposed surface of the wing-quills 

 much more greenish ; the sides, flanks, and white cervical collar with 

 little or no buffy tinge; the female is rather more brownish above, 

 especiallj'^ on the pileum, with the exposed upper surface of wing- 

 quiils more greenish (less bluish), and the cervical white collar and 

 lower parts lacking creamy or buffy tinge. 



The female of Sauropatis chloris amphiryta differs from the male 

 in much darker, more olivaceous upper parts, and in all lack of buffy 

 on the lower surface. 



A single adult male from Loh Sidoh Bay, on the mainland of 

 northwestern Sumatra, agrees so closely with specimens of the pres- 

 ent race from Nias Island that it seems to be referable here rather 

 than to any of the other subspecies. 



The colors of soft parts, so far as mentioned on the labels of speci- 

 mens are: Maxilla black; mandible pinkish white, with tip and edges 

 black.
