.with the present specimens, and it is’ not easy to find out the 
distinguishing characteristics from the descriptions only. 
Thomas’s miodon from Shensi is perhaps to be excluded, 
because it has a smaller, especially shorter, skull. When 
describing it, the author quoted compared it chiefly with 
E. dealbatus, and as this belongs to another group (nowadays 
even another genus) the characteristics of miodon used to 
distinguish it from dealbatus, as, for instance, the small size 
of p*, are shared also by the Mongolian Hedgehog, because it 
belongs to the same natural group. 
The name przewalskii was given by Satunin to a hedgehog 
collected in ‘‘ Nord-China?”’? The description of the same 
agrees very nearly with the present specimens as well with 
regard to the exterior features generally as also with regard 
to cranial dimensions (cf. below). 
The general appearance has a certain resemblance with 
that of a European hedgehog, although a little paler, but on 
a closer examination it is widely different by reason of its 
very large ears, comparatively long tail, and absence of any 
bare median space between the spines of the crown. The 
spines are directed towards different sides, which partly may 
be due to the fact that they are curved, the curvature being 
most pronounced in their basal parts. The spines on the 
crown, which are decidedly more slender than those on the 
back, are also less curved, They are brown at their base in 
varying degree, then follows a white ring and again a dark 
brown or blackish ring, which occupies the greater part 
of the distal half. Outside this is a subapical white ring, 
and finally a short brownish tip. The length of the spines 
is about 21-23 mm. The hairs are not quite so coarse as 
in a Common Hedgehog, and not at all so bristly as in 
E. koreanus. The snout and the surroundings of the eyes 
are brownish grey, the forehead paler, almost brownish 
white. The long hairs on the sides of the neck above the 
shoulders and along the flanks are white, the shorter hairs 
somewhat greyish. The whole underside is dirty white, 
more woolly in the young one. The fore feet have a colour 
somewhat resembling “ otter-brown ” (Rép. de Coul. 354°4), 
the hind feet a little darker and more brownish. The ears 
are fringed with hairs similar in colour to those on the fore 
feet, but almost naked on the outside, inside with white hairs. 
The vibrissze on the sides of the snout are rather well 
developed and black. The total length of the larger dry 
specimen is about 21 cm. The hind foot of the same (s. u.) 
is 41 mm. and the dry ear about 24 mm. It is, however, of 
course, very much shrunk, which is proved by the fact that 
the ear of the somewhat smaller alcoholic specimen is from
