3. Notes on some Japanese Mammalia. By Dr. A. 

 GuNTHER, F.R.S., Keepar of the Zoological Department,

[Received May 22, 1880.] 

 (Plate XLII.) 



I have recently had the opportunity of examining two collections 

 of Mammalia made by Messrs. H. Pryer and C. Maries in various 

 parts of the Japanese islands. Several desiderata and the more in- 

 teresting specimens were acquired for the British Museum, and on 

 some of them I beg to offer the following remarks. 



Urotrichus talpoides, Temm. (Plate XLII.) 



During the examination of the series of specimens in the British 

 Museum I have met with some points which do not seem to have 

 been hitherto noticed in the descriptions of this species. 



1. Tlie colour of dried specimens is a dark sooty brown ; and the 

 same coloration I notice in an adult female, preserved in spirits, 

 obtained by Mr. Maries near the river Nikko, in Nippon. This spe- 

 cimen is adult, as shown by the fully developed condition of its 

 generative organs. A second female (Plate XLII. fig. B), found by 

 Mr. Pryer near Yokohama, likewise fully adult, possesses a fur of a 

 highly iridescent colour, a bright sapphire-green being visible in 

 whatever direction the animal is viewed. I cannot observe any other 

 difference between this and the former specimen, except that it has 

 the tail beset with longer and denser hairs. It would be interesting 

 to know whether the iridescence of the hairs is apparent at certain 

 seasons of the year only. 



2. In the milk-dentition of an immature example, the skull of 

 which, however, is 26 millims. long, I notice that each of the anterior 

 incisors is strongly lobate on its outer margin near the base ; also the 

 second incisor shows an indication of a similar lobe, and is much less 

 conical than its successor ; the premolars and molars of the milk- 

 as well as permanent dentition show a remarkable agreement both as 

 regards number and form.. 



I have compared on this occasion with the Japanese species the 

 North-American Urotrichus gibbsii, Bd., of which an adult male
