Bare area on the head well developed, beginning between the eyes and prolonged 
backwards to the nape, expanded between the ears and narrowing to a point. Spines 
longitudinally grooved, nodose. Head long and pointed; ears very large and broad, 
rounded at their tips, the middle of their external borders nearly straight. Tail 
rather long, well haired. Fur soft and silky. There are from 17 to 22 longitudinal 
ridges on the spines; those on the back 21 to 28 mm. in length, those between

tract does not extend on to the forehead anterior to the inner borders of the ears. 
Limbs decidedly long. Fore foot short and broad; pollex well developed; claws 
strong, short; a large broad pad below the wrist, extending from the proximal pad of 
the pollex almost to the external border of the foot, and sometimes divided into two 
sections, the larger being external. Hind foot small; hallux very small. The rather 
small plantar pad longitudinally divided, the inner portion slightly the larger, with 
numerous small granular eminences between it and the digital pads. The mesial 
line of the tarsus towards the heel nude, the sides of the plantar surface and before
