Tijpe in collection. 



liemarlcs. — The diagnosis of this species gives its diffei'ential 

 characters as compared with A. celehensis, macMoti, and gilcus. 

 From A. juhatus and lucifer, Avith which it closely accords in its 

 dentition, the form of the ears, and the general colour of the head 

 and body, it differs chietiy in its much smaller size and the absence 

 of any trace of a buffy nuchal patch. Externally (ears, colour, size) 

 it shows much resemblance to Pteropus liifpomelanux macassar ia(s, 

 which also occurs in the Talaut Islands ; from the ordinary (non- 

 melanistic) phase of that form A. humilis is, however, easily 

 distinguished externally by having the russet colour confined to 

 the mantle, sides of neck, and foreneck, not extcndiug to the crown 

 nor to any part of the breast and belly.
