gradually fading as well upwards as downwards. Above the 
same is a narrower ring of white or brownish white, and, 
finally, a short brownish tip. In some cases the broad 
brownish ring is so evanescent that the result is a white spine 
with a short brownish tip. In the smaller (younger) speci- 
mens the pure white spines are few, and among the others 
the brown rings are often darker and may reach down to the 
root of the spine. By this the general colour becomes 
darker. The length of the spinesis about 18-21 mm. The 
hairs of the big specimens are white, a little greyish or 
brownish in the face. Ears short, rather broadly rounded, 
concealed in the fur, almost naked on the posterior side, 
sparingly beset with short brownish hairs on the inside. 
Length from lower outer angle to tip about 20mm. The 
smaller specimens are brownish grey along the flanks below 
the spines, and also somewhat brownish in the face around 
the eyes and between them. The hairs on the feet are also 
somewhat brownish. The tail is very short, about 12mm. 
The claws are pale horn-brown with whitish tips on the fore 
feet, a little darker on the hind feet. The length of the 
latter without claws is in the big specimens 35mm. Length 
of head and body about 205 mm. (All measurements from 
alcoholic specimens.) 
The claws of the fingers are much smaller than those of 
Erinaceus europeus, especially is this the case with those of 
the first, fourth, and fifth fingers. On the second and third 
hind toe the claws are not much smaller than in the Swedish 
hedgehog, but that of the fourth is plainly smaller, and this 
is still more the case with those of the fifth and first hind 
toes, the last of these latter sometimes almost looking 
rudimentary. The anterior plantar pads large and confluent, 
the two posterior also large and confluent only with a 
median groove, indicating their duplicity. The soles are 
somewhat rugose and there are also granular eminences, but 
few and only little defined. None of that kind is seen 
behind the posterior plantar pads.
