present specimen the teeth are less compressed antero- 
posteriorly and are more square in plan. 
As nothing is as yet known of the form of the canines and 
incisors, the “attribution of this species to the genus Jeta- 
mynodon i is tentative. Another Oriental species—J/. birman- 
ensis,—smalier than the present one, has been ascribed to 
this genus by Pilgrim Tf. It ts, Wee ccen , represented by very 
fragmentary remains, and seems to bet as near to Cadurco-

LXAXV.—Some Remarks about Eastern Hedgehogs. 
By Einar Lonnsere, F'.M.Z.S. &e. 
Wuen recently classifying some hedgehogs from Eastern 
Asia, the present author had the occasion to study more 
closely the literature of this group. Among other papers he 
also studied an early, but very valuable paper by Sundevall 
(‘“ Ofversigt af slietet Erinaceus,” K. Vet.-Akad. Handl. 
Stockholm, 1841). 
In this the author quoted spesks about thirteen different 
species of hedgehogs, some of which. he describes for the 
first time. These are arranged in two groups, and about 
them Sundevall expresses his opinion in the following terms : 
“The known species show such a great agreement in 
structure that they may be regarded to constitute a single 
indivisible genus ; but, as, nevertheless, some of them, viz. 
those which in the following constitute the second section, 
evidently form a small, extremely natural, subordinate group, 
many naturalists, who love to make new genera, may 
consider that they ought to separate them as an independent 
genus, and I wish to their service propose to use for this 
group the name Er7ciuws. It will, however, in such a case 
he. necessar y to separate generically in a similar way 
E. ethiopicus and E. heterodactylus, which differ as much 
from each other as from #. auritus and europeus.”’ 
From this itis apparent that. Sundevall recognised that the 
hedgehogs, in spite of their general agreement, could he 
divided into certain groups. Only for one of these groups 
he proposed, although with a certain humour, Hricius as a 
name of subgeneric value, but at the same time he admitted
