418 DR. J. ANDERSON ON A NEW [May 21, 



a large Ungulate pad on the middle of the plantar surface, which 

 is sparsely covered with hair from the heel to the pad. Claws 

 moderately long. Tail short, about half the length of the hind 

 feet. Spines finely striated, the longest about 18 millim. in 

 length and 1 millim. in diameter. The inter-aural spines are not 

 quite so long as the longest body-spines. 



The apices of the spines are generally yellowish white, passing 

 into a narrow orange-yellow band, which merges into a brown band 

 followed by a broad yellowish or white band, the basal ends of the 

 spines being dusky. 



The face anterior to the eyes, and the chin, are nearly nude, the 

 skin of these parts having a livid hue and sparsely covered with 

 minute dusky hairs, those along the margin of lips being whitish. 

 The ears also are nearly nude, of a livid hue, and are only sparsely 

 clad with short hairs. The fore and hind limbs are thinly clothed 

 with brownish and yellowish hairs. The lower part of the belly 

 and the area behind it are covered u'ith brownish fur. The head 

 behind the livid snout and chin, the sides of the body below the 

 spines, the throat, chest, and upper part of the abdomen are all 

 yellowish white.

The skuU of E. sclateri is much smaller than that of E. frontalis. 

 Smith, the only species, next to E. algirns, with which it can be 

 compared, but it is more closely allied to the former than to the 

 latter. The difference in size between the skull of the British 

 Museum specimen of E. frontalis. Smith {E. diadematus, Dobson, 

 but not of Fitzinger), which is a male, and that of E. sclateri, 

 which is a female, is greater than mere sexual dissimilarity would 

 account for. It should be viewed in connection with the differ- 

 ences that exist between the two animals when their external 

 characters are studied, and which are such that I have had no 

 course left me but to regard them as specifically distinct. 



In E. frontalis the spines between the ears instead of being 

 rather shorter than the body-spines, as in E. sclateri, are decidedly 

 longer and form an eminence between the ears. It has only a 

 single large pad below the wrist, whilst in E. sclateri there are 

 two placed side by side. The hind foot of E. frontalis has an 

 acutely pointed, well-developed, nipple-like tubercle, opposite to 

 the hallux, whereas in E. sclateri there is a broadish flat Ungulate 

 pad in a similar position. The ears also of E. frontcdis are
