of the forearm. The fur over the sacrmn is not differently colored 

 from that of the back. 



The fur below the anus is long, gray, unicolored, and forms a con- 

 spicuous mass of hair between the thighs. 



The thighs are clothed to a point nearly to the ankle with tawny- 

 brown, or gray fur. 



Posteriorly the posterior extremity is covered to the base of the 

 metatarsus, or to the bases of claws, with hair of the same color. 



(2) An adult skin. 



The color essentially the same as above. The crown is of a dark 

 iron-gray color. The color of the side of the neck distinctly domi- 

 nates the back of the neck as well as the front. 



P. edwardsii, P. vulgaris, P. rubricollis being all from the same 

 localities, viz., Madagascar, the following statements respecting them 

 may be useful : 



In all the crown is distinct from the neck ; the cheek hairy ; the 

 whisker is present ; a disposition exists for the circumpalpebral hair 

 to be distinct ; the labial hairs are abundant and of black color ; the 

 color of the side of the neck not markedly dominating that of the 

 back or the front; the side of the trunk di^stinctly differentiated. 



P. rubricollis is different from the other species, inasmuch as the 

 hairs are not dark at the base and (with the exception of the tips) 

 are of the same color their entire length. 



Pteropus edulis. 



Seven specimens examined. 



(1) An adult skin (No. 2745). 



Crown black with dark red tips. The patch extends well between 

 the eyes. 



Base of auricle naked. 



" Whisker " narrow, — confined to a rather small tract, which meets 

 the backward directed black hair of the face to form a " cowlick." 



Cheek patch is absent. 



Labial hairs inconspicuous, scarcely differentiated from those of 

 the face. 



Circumpalpebral patch absent. 



Side of neck with long, stiff, unicolored, reddish hair distinctly 

 dominating the back of the neck to form a mantle, but yielding to 

 the ventral colors on front of the neck. 



Post-mental tuft of black hair conspicuous. Black hair extends 

 on the face and the neck as far back as the line of the ears.
