2. PTEKOPTJS. 67 



Hair covering the sides of the face peculiar, long, and directed 

 backwards towards the ears ; on the back and arms closely appressed ; 

 fur of the back occupying a space more than two inches wide across 

 the loins ; wings one inch apart at their origin from the sides of the 

 back ; legs nearly naked ; beneath, the antebrachial membrane and 

 the wings between the humems and femur and along the forearm 

 are covered with woolly hair. 



Upper incisors of peculiar shape, long, narrow and acutely pointed, 

 separated by slight intervals from each other ; lower outer incisors 

 about twice the diameter of the inner ones and much longer ; inner 

 incisors close together in front ; all the lower incisors in young indi- 

 viduals bifid ; no trace of first upper premolar : third upper premolar 

 with an antero-internal basal process as in Pt. juhatus, last molar with 

 an antero-external cusp, and larger than the first lower premolar, 

 which stands in the centre of the space between the canine and second 

 premolar ; last lower molar about the size of the first premolar. 



Length (of the type specimen), head and body about 9", ear l"-25, 

 eye from tip of nostril l"-05, forearm 5"-2, thumb 2"-4, third 

 finger— metacarp. 3"-7, 1st ph. 2"-7, 2nd ph. 4"-l ; fifth finger— 

 metacarp. 3"-7, 1st ph. l"-65, 2nd ph. l"-6 ; tibia 2"-3, foot l"-8.

Type in the collection of the Leyden Museum. 



This species is easily distinguished by the long ears (which, in 

 proportion to the size of the animal, are probably longer than in any 

 other species of the genus) and peculiarly long fur on the sides of 

 the face. The dentition is also very characteristic, and the presence 

 of a smaU antero-internal basal cusp in the third upper premolar 

 connects it with Pt. juhatus.

Smaller than Pt. mackhtii, but generally similar to it in the 

 colour and distribution of the fur, and in the long ears, which are, 

 however, comparatively broader, and the antero-internal basal pro- 

 cess of the third upper premolar is not so much developed ; the 

 incisors are similar in both species. 



Fur of face and head rather long, yellowish buff; neck similar, 

 but brighter yeUow ; shoulders bright buff; chin and throat brown, 

 with some shining hairs ; neck, chest, and abdomen bright yellowish 

 buff; back dark yellowish brown; fur of humerus very short, 

 appressed, none or very little on the forearms ; legs naked ; distri- 

 bution of the fur on the membranes beneath similar to that of Pt. 

 macMotii, but the hairs are shorter. 



Length (of the type specimen), head and body about 8", ear 1"-1,
