In comparing the present species with the descriptions of hedgehogs known from 

 Asia and adjoining territories, and which belong to the section Hemiechinus, — charac- 

 terized by having the ridges on the spines tnberculated and five toes on all feet, — I find 

 that E. atliiopicus, Ehrenberg, = E. br achy clad ylus, Wagner, is most closely allied to it. 

 It slightly differs in coloration, in having the forehead white, the chest brownish ; each 

 of the tubex-cles on the spines is seated on a separate eminence, and the tail is 

 longer. Other similarly coloured species are E. algirus, cegypticus, pallidus and Ubicus, 

 all from North Africa, but they more or less differ in structure. Besides that there 

 are two other African species E. platyotis and pedoralis,* both of which are quite 

 different in coloration, and E. auritus, Pallas and hypomelas, Brandt, are from Nor- 

 thern Asia. 



From India Jerdon describes out of the section Hemiecliinus, E . collaris and mi- 

 cropus, the former being found in Northern, the latter in Southern India. 



In collaris the ears are externally somewhat indented, but not to any particularly 

 large extent. The spines are rather long and cylindrical, usually with a broad black 

 tip, each is surroundrd by 22 to 24 longitudinal grooves separated by equally broad 

 ridges, which are rather sharp and somewhat distantly finely tuberculated. 



Very closely allied to collaris are no doubt Bennett's E. Grayi and spatcmgus, both 

 from the Himalayas ; but until authentic specimens had been examined, it does not 

 appear advisable to identify all three. 



In E. Grayi each spine is stated to be yellowish white for more than half its 

 basal length, followed by a narrow blackish ring, and again white at the tip. The 

 coloration of the head and underside does not appear to differ from that of collaris. The 

 ears are said to be long, obtusely pointed, but scarcely thickened towards the tip, 

 and laterally not emarginate. 



E. spatangus is said chiefly to differ by the regular position of the spines, but 

 this is a character which very much depends upon the position of the body. It seems 

 probable that the type specimen is only a young one of E. Grayi, should this really 

 prove to be distinct from collaris. 



E. mentalis, Gray, also from the Himalayas, is recorded as distinguished from 

 others by a black chin; nothing further is known of it. 



In micropus, which is undoubtedly the same as nutliventris, the spines are thin, 

 rather short, with a long point and of a similar colour as in E. pictus, but each is sur- 

 rounded by 17 or 18 longitudinal grooves, separated by only very little broader ridges 

 which are provided with moderately distant blunt, and nearly rounded tubercles. 



From Afghanistan, Blyth described E. megalotisfi which in colouring more resem- 

 bles hypomelas than auritus, each spine being dusky at base and near the middle, and 

 blackish brown towards the tip, which again is paler. Each spine is further surrounded 

 by about 28 to 30 longitudinal fine furrows, separated by about equally broad and fine 

 ribs, which are minutely tuberculated ; some of the ribs are occasionally thinner than 

 others. This character alone separates megalotis from the two other allied species 

 with large ears. 



In looking over the specimens of hedgehogs in the Indian Museum I noticed an 

 apparently new species which was lately collected by Dr. Henderson when accompany- 

 ing the Yarkand expedition, and I shall give a short description of it under the 

 name of
