LXII. — A Collection of Mammals from Northern and Central 

 Mantchuria. By Oldfield ThoMAS. 



(Published by permission of the Trustees of the British Museum.) 



The Britisli Museum has acquired from Mr. ALin Ovvston a 

 collection of small mammals made in Mantchuria by Orie, a 

 Japanese, who collected at the same time the birds recently 

 enumerated by Mr. Collingwood Ingram in the ' Ibis' *. 



The majority of the specimens were obtained in the 

 Ivhingan Mountains, at about an altitude of 3800 feet, at the 

 point where the Siberian Railway cuts the range. The 

 remainder were obtained in the neighbourhood of Chang 

 Chun, in Kirin Province, on the Harbin-Port Arthur branch 

 of the railway. 



These Mantchurian mammals are of particular value to us 

 as being from an intermediate locality between the Ussuri 

 and Amur region, woriced by Schrenck and others, and the 

 Mongolian plateau, whence the Museum received the valuable 

 series collected by M. P. Anderson and presented by the 

 Duke of Bedford f. 



As might be expected, many of the forms are intermediate 

 in character between the Mongolian and Amur animals, and 

 form intermediate but well definable subspecies. 



The collection consists of about 100 specimens, belonging 

 to 15 species, of which five prove to need description as local 

 subspecies. 



1. Vespertilio murinus, L. 



? . Chu Chia Tai, Kirin Province. 



The size of this specimen is quite as in Scandinavian 

 murinus^ not as in the Chinese superans. 



2. Erinaceus amurensis, Schrenck (?). 



? . Chang Chun, S. Mantchuria. 



The inter-relationships of E. amurensis, Schrenck, cleaJha- 

 ius, Swinh., orientalis^ All., cMnensis and iissuriensi's, Sat., 

 need much more material for their elucidation. All are very 

 closely allied, and owing to the almost complete ignoring by 

 each writer of his predecessor's work, no trustworthy com- 

 parisons have been made between them.
