56 PTEROFODID^. 



The fur is altogether much longer aud more woolly on the head, 

 neck, and shoulders, and inferior surface of the body than in Pt. 

 edwardsii. and across the back occupies a space nearly three inches 

 ■wide, leaving the anterior extremities nearly naked ; but the thighs 

 are well covered, and a few hairs extend upon the tibise, while the 

 interfemoral is quite concealed by the long fur in the middle. 



Teeth as in Pt. edwardsii ; lower incisors distinctly grooved. 



The single type specimen, a skin in indifferent condition, affords 

 the following measurements only : — Length of ear l"-2, breadth of 

 ear 0"-8 ; length of third finger — metaearp. 4", 1st ph. 3"-5, 2nd ph. 

 5"-l ; fifth finger— metaearp. 4", 1st ph. 2"-3, 2nd ph. 2"-3. _ 



On the whole this species appears to correspond closely in size 

 with Pt. edwardsii, from which the shape of the ears and the quality, 

 colour, and distribution of the fur at once distinguish it.
