This fine series of specimens fully bears out Mr. Thomas's remarks 

 (P. Z. S. 1898, p. 245) that, so far as our present knowledge is 

 concerned, the variations met with in this species apparently follow 

 none of the ordinary laws which are usually supposed to govern 

 such cases.

All the specimens in this collection belong to that form of 

 Mus rnttes which is found throughout Southern India and Ceylon. 

 The general colour is 1 ight fawn, and the long black hairs are numerous 

 and distinct. There are practically no spines, and the tail is longer 

 than the head and body. They do not agree with the types of 

 MM. fbrvescens, rufegcens, brunneuscidus, or nitidus, but in shape 

 and colour most nearly approach the true Mus rattus, under which 

 name 1 have therefore placed them.
