given by Scott and Osborii for Metanii/noJon*, but in the 

 present specimen the teeth are less compressed antero- 

 posterior!)' 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 Meta- 

 vit/twdoti is tentative. Another Oriental species — AJ. I'lrnian- 

 enxis, — smaller than the ])re80iit one, has been a.>eribed to 

 this geiuis by Pilgrim t. It is, however, represented by very 

 fragmenting remains, and seems to be as near to Cadurco- 

 therium as to Metatnynodov. 



LXXV. — Some Remarks about Eastern Hedgehogs. 

 By ElXAH LONNBEKG, F.^l.Z.S. &c. 



AVhex 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 au early, but \*i\\ valuable j)aper by Sundevall 

 ("Ofversigt af sliigtet Krinaceus,'' K. Vct.-Akad. Haudl. 

 Stockholm, 18-Al). 



In this the author quoted spe;iks about thirteen diflerent 

 species of hedgehogs, some of which lie describes for ihe 

 first time. These are arranged in two groups, and about 

 them Sundevall expresses his opinion iu the following terms : 

 ''The known species show such a great agreement in 

 structure that they may be regarded to constitute a single 

 iDdivisible geuus ; 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 

 j;roup the name Ericivs. It will, however, in such a case 

 be necessary to separate geneiically in a similar way 

 E. (elhiopicus and E. heterodactylus, which difler as much 

 IVom each other as from E. uuritus and eurojjaus.'' 



From this it is aj)parent that Sundevall recognised that the 

 hedgehogs, in spite of their general agreement, could be 

 divided into certain groups. Only for one of these grouj-s 

 he proposed, although with a certain liunKnir, Ericitis a!« a 

 name of subgencric value, but at the same time he admitted
