the notch to the tip 32mm. The tail measures 25 mm.. 
from vent. 
The claws are long and strong. Those of the fore feet of 
the old specimen are truncate at the tip, evidently worn by 
digging. ‘They are horny white, and their degree of develop- 
ment is about the same as in the Common Hedgehog, thus 
no incipient reduction anywhere as in H. dealbatus. 
The plantar pads are distinct, not confluent. Between and 
behind them are numerous granular eminences. 
The only real discrepancy between this and Satunin’s 
description, as far as it goes, is that he says that the length 
of the ear is only 19 mm., but this may be explained by the 
fact that his type-specimen was mounted, and this organ 
may therefore have shrunk yery much. 
The following cranial measurements of the present old 
hedgehog from Mongolia agree on the whole with those of 
Satunin’s specimen, so that they certainly do not prohibit 
an identification, On the other hand, there is not much 
difference between Satunin’s measurements and those by 
Radde, which are referred to dauuricus, Sundevall. It seems 
therefore hardly possible to tell, for the present, whether 
Satunin’s przewalskii really differs from the same, and if 
they are synonymous Sundevall has half a century priority. 
In any ease przewalskit cannot be more than a subspecies of 
dauuricus :—

The sagittal crest is low and not much developed, and it 
does not reach in front of sutura coronalis. he premax- 
illary is rather broad behind, but just at the nasal suture it 
is produced in a narrow tip, which on one side meets the 
nasal process from the frontal, on the other leaves a short 
contact between the nasal and the maxillary. The posterior 
end of the nasals reaches to the level through the for. lacry- 
male.
