gray above, dirty white beneath. These animals can be distin- 
guished from Rattus by their broad molar teeth, the transverse 
ridges on which are continuous from side to side instead of being 
divided into three tubercles on each ridge. An accompanying 
character (which is not completely diagnostic) is the presence 
in females of 6 pairs of nipples, 3 pairs on the chest and 3 on 
the belly. In a special subdivision of the genus, sometimes sepa- 
rated under the name Gunomys, the number of nipples may vary 
from 16 to 18. The animals are ground-dwellers and good 
diggers. 
The distribution of the Bandicoot Rats is tropical ; they are 
found in India, Burma, Malaysia, and as far north as Yunnan 
and Formosa. The typical species of Bandicota is B. indica from 
Pondicherri, the east coast of the Indian Peninsula. These are 
large Rats, the hind foot about 2 inches long. The color, like 
most, is iron-gray above, grayish white beneath. Close relatives 
of B. indica are B. nemorivaga from Nepal, northern Siam, 
Yunnan, and Formosa; savilei from Mt. Popa, Burma, and 
western Siam, and siamensis from central Siam. In animals of 
this group the head and body measure about 9 inches, the tail 9 
inches. B. savilei is smaller, the hind foot 1% inches; B. siam- 
ensis is larger. 
In Formosa a Bandicoot Rat, kragii, is recorded by Kuroda 
with the length of head and body 6% to 7 inches, tail 5% to 7 
inches, hind foot 1% to 1% inches. This may belong to the sec- 
tion Gunomys. 
The Giant Bandicoot Rats, B. gigantea, of the Malabar 
coast, are represented in Annam by the race B. g. jabouillei, 
which seems to be the largest form known. The foot measures 
2% inches, the length of the skull 2% inches. 
The Bengal Bandicoot Rats, B. bengalensis, or Gunomys 
bengalensis, are smaller and their females have more numerous 
mammae. The eastern races are B. b. varius and varillus of Pen- 
ang, Malay Peninsula, which are described as larger and smaller 
races occurring on the same island. In Kashmir, a mountain
