1901.] A NEW HEDGEHOG. 287 



Differs manifestly from E. alhulus, with wliich it has been eon- 

 founded by many authors, in its smaller size, shorter ears, darker 

 colouring, and broader skull, as will be seen in the table of 

 measurements at the end of the present note. The geographical 

 distribution of this species is far more restricted than it was 

 commonly supposed to be. It does not go farther south than the 

 Ust-Urt in the Transcaspian province, whence it has been re- 

 corded by Zaroudnoi, Eadde and Walter, and others. These data are 

 based on the confusion of this species with E. albulus. I have come 

 to this conclusion after having examined the specimens in the 

 Caucasus Museum (collected by Dr. Eadde and Dr. Walter), as well 

 as a great number of Hedgehogs received by me from Transcaspia 

 through my correspondents. I know, from there, only E. auritus 

 and E. macr acanthus. The distribution of E. aiiritushegms in the 

 steppes of the Northern Caucasus, in the plains of the Manytsh ; 

 it then extends to the north between the Don and the Yolga, 

 up to the hillocks of Ergheni, and thence goes eastward through 

 the Volga-Dral and the Kirghiz steppes approximately between 

 45° and 55° IN", lat. How far its distribution extends to the 

 East is not well known. Pallas says that it reaches Lake Baikal, 

 but the long-eared Hedgehogs which live along the Eiver Irtysh 

 are much larger ; and those of the Trans-Baikal attain a size even 

 greater than does E. enropceus, so that they doubtlessly belong 

 to some other species. It seems probable that the long-eared 

 Hedgehog does not extend to the East beyond the Balkhash- 

 depression and the 80th deg. of E. long. (Paris merid.). This sup- 

 position is confirmed by the fact that, though Middendorff ', 

 Schrenck ^, and Eadde ^ mention in their works E. auritus from 

 Eastern Siberia, they do so on the testimony of Pallas, but have 

 not themselves succeeded in finding this species there. 



What E. dauuricus Sundev.'' is, I do not know, but according 

 to what Pallas says of the long-eared Hedgehogs of Daooria, 

 it is very probable that it belongs to some distinct, but now over- 

 looked species.
