the notcli to the tip '.Vl mm. The tail measures 25 mm. 

 from vent. 



The claws are lotij^ and strong. Those of the fore fiict of 

 the old specimen are truncate at the tip, evidently worn by 

 clijrcrinur. Thcy 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 E. dealbafnif. 



The plantar pads are distinct, not continent. 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 very much. 



'IMie 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 racasurements 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 c^i^a przewalskii 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. The 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 i\\Q for. hicry- 

 uiale.
