Head rather short; muzzle moderately long and pointed, more so in some specimens 
than in others; ears very large, erect, high above the spines, somewhat pointed, but 
rounded at their tips, external margins straight or slightly emarginate, height 35 to 
38 mm.; tail short, nearly nude in some specimens, haired in others. 
Fur soft and silky. The spines not extending on to the forehead in front of the inner 
border of the ears. Spines on the back 15 to 19 mm., those between the ears 13 to 
17 mm. in length; diameter of spines 1 to 1*2 mm.; with 20 to 26 longitudinal 
nodose ridges. 
Limbs moderately long; fore foot large, fingers long; claws strong, long and curved ; 
pollex well developed, its claw rather long, as long as the claw of the 3rd finger; the 
claw of the 5th finger nearly as long as that of the 1st; on the fore foot there are two 
prominent tubercles close together side by side, immediately below the wrist, the inner 
the smaller. Hind foot with hallux well developed; toes long, claws long ; third and 
fourth toes subequal, the fourth sometimes the longer ; two minute nearly obsolete 
tubercles rather close together external to the hallux and placed obliquely, the external 
being the more distal. 
The front of the face below the eyes, the fore feet, and the hind limbs from the 
middle of the tibia downwards are pale brown ; the rest of the fur whitish. The 
skin of the back of the ear, the anterior surface of the ear along its internal and 
external border dusky brown; the middle area of the front of the ear yellowish 
white. Tail dusky brown. Spines with yellowish-white tips; a brown band below, 
twice as broad as the yellow tip, succeeded by a broadish yellow band, the base of 
the spines generally dusky. The head-spines have the same markings. 
The extent to which the apex of the spine is tipped with white is very variable; also 
the intensity of the dark brown band below the tip varies greatly, in some cases it is 
nearly black.
