the C. ilensis group (see below). This distinctly northern 
group of forms includes all of the members of Crocidura from 
north and east of China except the large, isolated Yamashina's 
Shrew and the Korean thomasi, which by reason of its larger 
size falls into the southern group, dr acuta (see below). The 
assembly represents a northeastern outpost of an otherwise 
tropical genus, adjusted to northern climatic conditions. The 
colors vary from very dark brown to slate, the undersides little 
if any paler. The dimensions of the north Asiatic group vary 
from: length of head and body 2% to 2% inches, tail 1% to 2 
inches, hind foot approximately % inch. 
The remaining species of Crocidura with which this book 
deals are found mainly in southern Asia. For practical purposes 
they can be distributed among four groups, representing size 
and proportions. The first contains only the short-tailed C, 
pullata of Kashmir. The second, which includes a number of 
forms from a wide range of territories, has the length of head 
and body between 3 and 3% inches and only a little in excess of 
the length of the tail, while the length of the hind foot varies 
from % to % inch. This group is well typified by C. dracula of 
Yunnan. 
The third group comprises slightly smaller Shrews exem- 
plified by C. rubricosa of Assam, in which the length of the 
head and body is less than 3 inches and more than 2% inches ; 
the length of the tail varies from 2 to 2% inches, and of the hind 
foot is about % inch. This group also has a wide geographical 
representation. 
The fourth group consists of C.Jlensis and its subspecies. It 
is characterized by its short tail, l 1 /^ to 1% inches, and small 
foot, % to %' inch. Typically (in central Asia) this is a very 
small species; but the race C. i. shantung ensis includes larger 
individuals in which the length of head and body may reach 
3% inches. The ilensis Shrews are colored dark brown above, 
without as much gray as in other groups ; their underparts are
