upper incisors in cross section ; the antepenultimate molar above ia 

 smaller than the preceding tooth : the last molar has two blunt an- 

 terior cusps as in the other molar teeth, and equals or slightly exceeds 

 one of the outer incisors in cross section ; the lower molars are deeply 

 grooved, and the sides of the groove forming the outer and inner 

 cusps are notched above ; all the teeth remarkably broad and strong 

 (Plate IV. figs. 1, 1 a, 1 h). 



This very peculiar dentition has not been previously noticed. It, 

 no doubt, indicates some important difference in the food of this 

 species from that of most of the other species of the genus.

Ears as in Pt. Iceraiulrenii, shorter than the muzzle, narrowly 

 rounded off above. 



Interfemoral membrane very narrow in the centre, concealed by 

 the fur. 



Muzzle grey ; face about the eyes and forehead brown with nu- 

 merous silvery grey hairs ; head reddish brown, extremities of several 

 hairs greyish or shining; nape of the neck and shoulders bright ferru- 

 ginous brown,duller beneath; fur of the back short, appressed, extend- 

 ing for about half an inch on the membranes on each side beyond their 

 line of origin from the back, dark reddish brown, extending also in a 

 thin line upon the humerus and upon the fleshy part of the forearm ; 

 rump and legs almost as far as the ankles covered with long, woolly, 

 yellow hairs, which completely conceal the narrow interfemoral 

 membrane in the middle ; breast and upper part of abdomen of the 

 same colour as the back ; abdomen and thighs as on the upper 

 surface. 



Incisors and molars large, well developed, the latter without basal 

 cusps or ridges ; lower outer incisors three times as large as the 

 inner ones ; first upper premolar nearly as large as one of the inner 

 lower incisors ; second premolar not widely separated from the 

 canine ; first lower premolar nearly filling up the space between the 

 canine and second premolar, larger than the last upper molar ; last 

 lower molars small, circular, about half the size of the outer lower 

 incisors ; postorbital processes of the frontal scarcely more than 

 half circumscribing the orbit, no corresponding zygomatic process ; 

 facial bones rather short, as in Pt. aneiteanus, which, on the whole,
