Descriptions of East Asiatic Mammals 37 
H. siamensis as head and body 6% inches, tail 1 inch, and hind 
foot 11 /i2 inch- 
Lesser Gymnures were first discovered on the island of Java. 
Continental races have been distinguished as follows: H. s. 
pegnensis from Tenasserim and southern Burma, north to 
Yunnan, China; H. s. siamensis from northern and eastern 
Siam, the isthmus of Kra and Annam, a close relative of pe- 
guensis; and H. s. microtinus (meaning "like a meadow 
mouse") from Tonkin, Laos, and Annam. H. s. siamensis has 
been trapped under logs in wild banana groves in northern Siam 
at 4300 feet. 
The Chinese Gymnure, genus Neotetrachus, is closely re- 
lated to Hylomys. The length of its tail amounts to half of the 
length of its head and body, instead of being only as long as 
the hind foot. The snout is not quite so long in proportion, and 
there are fewer teeth. The only known species, N. sinensis, is 
colored dull olive-brown above, buffy gray beneath, with the 
sides of the head slightly tinged with russet. The length of the 
head and body is 4 or 5 inches, the tail 2 to 2% inches, the hind 
foot about 1 inch. This animal is best known from Hsikiang, 
Szechwan, and Yunnan, all provinces of China. It is present 
in the basin of the Salween River between 7000 and 8000 feet. 
A race, N. s. cuttingi, which occurs in northeastern Burma be- 
tween 7000 and 9000 feet, occurs in cool damp forest where it 
uses the same runways as many other small mammals of the 
region. Another race, N. s. julvescens, found in Tonkin, has 
the underparts conspicuously more reddish than the animals 
from Yunnan. 
THE HEDGEHOGS (SUBFAMILY ERINACEIN^E) 
The Hedgehogs of China include two genera, Hemiechinus 
and Erinaceus. Hemiechinus, meaning "half spiny," has the ears 
long (l!/2 inches), and the spines on the crown of the head
