Fine straggling hairs clothe the inferior surface of the ulna and humerus, and 

 stretch out upon the membrane down along the sides of the body and upwards 

 upon the interbrachial membrane. Everywhere the hair is very soft. 



The skull is of medium size, not crested. The postorbital processes are long 

 and incline outward and downward to within two lines of the zygomas. The 

 intermaxillary bone is not thrown forward and downward as in other Pteropi, 

 but is on the same level as the roof of the mouth. The first premolar above 

 is larger than the incisors. The same tooth on the lower jaw is also of good 

 size, but less tubercular than in other species. 

 The dimensions are as follows : 



Length from nose to base of tail 8*0 



" " " commencement of membrane 3*0 



" of head 2-3 



" from nose to eye 1-0 



" " eye to ears 0-6 



Between eyes 0-9 



* " ears 1-3 



Height of ears O10 



Length of tail 0*3 



" superior extremity 6-6 



" thumb 1-71 



" first joint 0'4| 



' second joint 1-3 



" index finger 3 - 



" third " 8-0 



" fourth " 6-5 



" fifth " 5-0 



Envergure 26-0 



It will be observed that the length of the inferior extremity and the expanse 

 of wing membrane are greater than usual, when the other proportions are 

 taken into consideration.

Male. Upper side fulvous ; fringe of primaries alternately black and white, 

 of secondaries white ; on hind margin of primaries a broad black border, in 

 which is a series of fulvous lunules, the middle one largest and projecting, 

 preceded by a sinuous row of round fulvous spots which increase in size 

 towards the inner margin ; next, a fulvous band, the upper half of which 

 intersects the preceding row at the fifth spot, making it appear bifid on the 

 costal margin ; this band is edged anteriorly by a black line which is dilated 

 on costal and on inner margin ; on the discal arc a fulvous streak entirely 

 edged with black ; base of both wings covered by wavy confluent black lines, 

 as in Tharos. 



Secondaries have a narrow black marginal border, on the anterior edge of 

 which is a row of fulvous lunules, the one next the anal angle bisected longi-
