of markedly elongated paler hairs which are usually matted 
together by an oily liquid, perhaps of glandular origin. 
The Himalayan Water Shrew, Chimarrogale, is one of the 
aquatic representatives of the White-toothed Shrews just as 
Neomys is of the ''Red-toothed" or True Shrews. Like Croci- 
dura, it has 28 teeth. The typical race, C. himalaica, of Nepal 
and Burma, is represented by a distinct race, leander, in north- 
ern Chekiang and Fukien. Three other forms are known, C. 
styani from 11,000 feet in Szechwan and Burma, C. varennce 
from Annam, and C. platycephala from Japan. The ear, though 
very small, is present. The color of C. himalaica is slate-gray, 
with the tips of the hairs brown, the lower parts gray. The tail 
is gray-brown above, white beneath. In C. styani the line of de- 
marcation between the upper- and underparts is more strongly 
emphasized than in himalaica and leander. The three are prob- 
ably only subspecies of himalaica, though in varennce the tail is 
wholly black. The length of head and body amounts to 4% 
inches, of the tail 3 inches, of the hind foot % inch. 
The Japanese Water Shrew, C. platycephala "of the size of 
Sorex indicus" appears to be slightly larger than any of the 
Himalayas and to have the skull flatter than C. himalaica. 
Chimarrogale lives in the neighborhood of mountain streams, 
in which it swims freely. Its food is said to consist of small fish 
and crustaceans. It can be trapped at the sides of small water- 
falls in mountain streams, where it is compelled to leave the 
water in order to go from the lower level to the higher. 
This interesting genus is a very close relative of the Bornean 
Water Shrew, Crossogale. In fact, the latter is better considered 
as a subgenus of Chimarrogale. Together with the Japanese 
species, it represents an outstanding example of the discon- 
tinuous distribution of a specialized genus. 
The Web-footed or Tibetan Water Shrew, Nectogale, 
which also has 28 teeth, contains a single species, N. elegans 
from Szechwan, Shensi, Yunnan, Sikkim, and northeastern
