VII. — Notes on the Asiatic Bamboo-Rats (Rhizomys, etc.). 

 By Oldfield Thomas. 



(Published by permission of the Trustees of the British Museum.) 



In connection with the determination of a bamboo-rat ob- 

 tained in Burma during the Bombay Natural History 

 Society's Mammal Survey, I have examined all the speci- 

 mens of this interesting group in the Museum, and now 

 make some preliminary notes about them, with descriptions 

 of new species. 



The genus Rhizomys, as hitherto used, is evidently a 

 composite one, and three groups are distinguishable from each 

 other, typified respectively by the species sinensis, sumatrensis, 

 and badius, the first being the type of Rhizomys *, the second 



* Although both sinensis and sumatrensis were included in the genus 

 Rhizomys, when first formed by Gray, the former is fixed as the genotype 

 by the paragraph next before " Rhizomys" in the description: "The 

 third genus described was founded on a glirine quadruped nearly allied 

 to the Bamboo-Bat \Mus sumatrensis] "
