020 Prof. E. Lunnberg on Eastern Hedgehogs. 



Ptorvgoid fossa narrow, only 3'5 mm. where it is broadest, 

 liardly .'i nun. at posterior end. There is a rather broad 

 slielt behind the transverse posterior ridge of the palate, but 

 there is also a well-developed median spine (unlike in 

 E. orientahs, Allen). 



Geographically spoken, Erinacous orientalis, Allen, 1903, 

 and E. iissuriensis, Satuuin, 1906, are perhaps the next 

 neighbours to this hedgehog from Korea. The latter differs, 

 however, very much with regard to the striking coloratiou 

 of its lower side with its cinnamon and tawny shades, while 

 E. orientahs is said to have the " ventral surface very pale 

 yellowish,' and E. ussuriensis is in the middle of breast and 

 belly '^ greyish white," otherwise greyish brown with a mix- 

 ture of wiiite hairs. The shoulders of the latter appear to 

 have the last-mentioned mixture of brown and white hairs, 

 and in E. orientalis they are '^ pale greyish sandy brown," 

 but in the Korea Hedgehog white. The skull of the latter 

 is smaller than that of both the other species, and especially 

 is the shortness of the nasals striking, and this depends as 

 well on the shortness in front as on less extension backwards. 



Erinaceus chinensis, Satunin, 1906, from Chingan, is, 

 according to its author, covered on the lower side with 

 " dichter weisser WoUe,'' and it is thus rather different from 

 the Korea animal. The skull of the former is larger than 

 that of the latter and, although the single type-specimen 

 is said to be young, it had already longer nasals than the 

 old specimen from Korea. Satuuin expresses a suspicion 

 that possibly his chinensis may prove identical with dealbatus. 

 It is very difficult to form any definite opinion in this matter, 

 but it does not appear very probable. Perhaps it is more 

 related to orientalis. 



The difference between the Korea Herlgehog and E. deal- 

 batus is very great, not only with regard to the colour, but 

 also with regard to the smallness of the claws of the latter. 

 The cranial characteristics are also very dill'erent, e. g., the 

 difference in length of nasals.

Several names have been given to members of this genus 

 ( = Hemiechinus, Fitz.) found in Eastern Asia, e. g., dauuricus, 

 Sundevall, 184-1, albulus alaschanicus, Satunin, przewalskii, 

 Satuuin, 1907, and miodon., Thomas, 1908. Of these albulus 

 alaschanicus is easy to exclude at once from the comparison 

 with the present specimens, in consequence of its small size. 

 Tlie remaining three are much similar as well inter se as also
