By Dr. A. GUNTHER, F.E.S., Keeper of the Zoological Department, British Museum. [Received M a y 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 interesting 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. The 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 specimen 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 |
