is reported also from Burma ; this form is contrasted with the 
shorter-haired T. b. assamensis from Assam. A slightly browner 
form, which was formerly separated as T. b. yunalis, is the same 
as modesta, the former being in winter pelage, the latter in 
summer pelage. The broadly light-colored underparts seen in 
summer are said in winter to become much narrowed, and gray- 
based hairs become more numerous on either side of the nar- 
rowed strip of self-colored hairs. The Concolored Tree-shrew, 
T. concolor, is colored much as the Chinese animal but is larger, 
with the length of the head and body attaining 8 to 9 inches, 
tail 6% inches. This form is found in southern Annam and 
northern Cochin-China. 
The T. glis group is colored deep reddish. The number of 
nipples in females never exceeds 8. In the Red Tree-shrew, 
T. glis ferruginea, the color is composed of a mixture of red 
and blackish hairs and the tail is yellowish black above, blackish 
yellow beneath. The underparts of the body are buff, often with 
the gray bases of the hairs showing through. The length of head 
and body is 7 to 8 inches, of the tail 6 to 7 inches. This com- 
mon Tree-shrew occurs on the lower third of Malay Peninsula. 
Numerous local races are known from adjoining islands. T. glis 
cambodiana from the southeastern parts of the Siamese- Anna- 
mese Peninsula must be carefully distinguished from T. belan- 
geri modesta from the same general region. 
Wilkinson's Tree-shrew, T. lacernata wilkinsoni, which to 
some extent is intermediate between belangeri and glis both in 
its color and geographically, dwells in the middle part of the 
Malay Peninsula, north of glis and south of belangeri. 
THE HEDGEHOGS AND GYMNURES (FAMILY ERINACEID^) 
Although the Hedgehog family includes the largest Asiatic 
members of the Order Insectivora, none of its members is as 
large as a house cat. The Hedgehogs may reach a total length
