In comparing tho 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 tuberculated and five toes on all feet, — I find 
that E. cethiopicuB, Ehronberg, = E. brachydactylus, Wagner, is most closely allied to it. 
It slightly differs in coloration, in having the forehead white, the ohoBt brownish ; each 
•of the tubercles on the spines is seated on a separate eminence, and the tail is 
longer. Other similarly coloured species are E. algirus, (Egyptians, palUdus 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 pectoralis * both of which are quite 
different in coloration, and E . auritus , Balias and hypomelas, Brandt, aro from Nor- 
thern Asia. 
From India Jordon describes out of the section Hemiechinus, E. collaris and mi- 
cropus, the former being found in Northern, the latter in Southern India. 
In collaris the ears are externally somewhat indonted, 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 21 longitudinal grooves separated by equally broad 
ridges, which are rathor sharp and somewhat distantly finely tuborculated. 
Very closely alliod to collaris are no doubt Bennett's E. Qrayi and spafauq/ws, both 
from the Himalayas ; but until authentic specimens had been examined, it does not 
appear advisable to identify all throe. 
In E. Qrayi eaoh 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 collm-is. The 
ears are said to bo long, obtusely pointed, but scarcely thickened towards the tip, 
and laterally not emargmate. 
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. Qrayi, should this really 
prove to bo 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 nudiventris, the spines aro 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. megalotis,f winch in colouring more resem- 
bles hypomelas than auritus, each spine boing dusky at base and near the middle, and 
blackish brown towards the tip, which again is paler. Eaoh 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 tho 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
