264 Mammals of Eastern Asia 
nipples are on the belly. These animals are rather smaller than 
the Pennsylvania Meadow Mice that we know near New York. 
The color is gray-brown, with the tips of the hairs distinctly 
rufous in some forms. They are nocturnal and partly diurnal. 
In Burma they may be trapped in the rank grass of mountain 
meadows, or along the banks of trails and under rocks and 
logs. 
The typical species of Eothenomys, E. melanogaster (mean- 
ing "black-bellied"), occurs from Fukien in southern China to 
northern Burma and Assam. Other related species are E. miletus 
from Yunnan and Hupeh, E. eieusis also from Yunnan, E. libo- 
notus from the Mishmi Hills of Assam. The length of the head 
and body in E. melanogaster is 3% to 3% inches, tail 1% to 
1 % inches, hind foot % to % inch. E. m. columns from Fukien 
is larger, the length of head and body between 5 and 6 inches. 
E. miletus is also large but E. eieusis is smaller again, with a 
longer tail — about 2 inches. 
A subgenus of Eothenomys, named Anteliomys, is restricted 
to Yunnan and adjoining parts of southern China and Tonkin. 
Species included here are E. chinensis from Szechwan, and 
proditor, olitor, and custos, all from Yunnan. They vary in 
size according to species, just as typical Eothenomys do. 
Eothenomys chinensis has the head and body length from 4 1 / 4 
to 5 inches, the tail longer (2% inches), and the hind foot 
from % to almost 1 inch; E. custos, proditor, and olitor, on 
the contrary, have shorter tails. 
Caryomys, another subgenus of Eothenomys, contains only 
two species, E. eva from Shansi and Shensi, and E. ines from 
Kansu, Hopei, Shensi, Szechwan, and Jehol. In E. inez the 
tail is only 1 y 2 inches long, in E. eva 2 inches or more. 
The form of "Microtus" recorded by Blanford from the 
Himalayas, sikkimensis, is perhaps referable to Eothenomys. 
Other "species" in his list are forms of Alticola, a genus of the 
high mountains having a northwestern distribution.
