The Continental Long-nosed Tree Squirrels, Dremomys, 
are less specialized than the Sunda Islands Long-nosed Squir- 
rels; the head is less narrowed and the rostrum less elongated. 
There are 3 pairs of nipples. These Squirrels have an extensive 
continental range, including Burma, China, Malay Peninsula, 
Hainan, and Formosa. The type species is D. pernyi of Szech-

There are three main species groups in Dremomys: the type 
group D. pernyi of China, ranging from Fukien up the Yangtse 
to Szechwan and thence southwest into Burma, has the muzzle 
moderately lengthened, the underparts white, and the tail rusty 
beneath at the base only; the D. lokriah group has the muzzle 
short, the underparts yellow, and is found from Burma and 
Assam to Sikkim and Nepal; the D. riifigenis group, found 
from Burma, Yunnan, and Szechwan to the Malay Peninsula, 
Annam, and Hainan, has the muzzle extremely long, the cheeks 
red, and the whole of the underside of the tail red.
