labelling, but, until we have proof that this is so, I do not feel 

 justified in ranking the new form as other than a subspecies of 

 lokriali. The western series corresponds in all particulars with 

 Hodgson's co-tj'pes of that species and with a series of about a 

 score of other specimens collected by Hodgson in Nepal, and hj 

 Blanford and others in Sikkim. It may therefore be confidentl)^ 

 accepted as true lokrioJi. The eastern series I propose to call 



Bremomys lolriah bJiofia, sp. n. 



A Bremomys resembling lolriah in all structural characters, but 

 lacking entirelj^ the suffusion of ochraceous which marks that 

 species. 



Size and fur quite as in lolriah. General colour above darker 

 than in true lokriah, the grizzle much finer. The individual hairs 

 black, with a subterminal ring (about 1mm.) of "ochraceous buff"," 

 in lohriah the hairs have two rings, each of them double the width 

 of the single ring in the present form. The face in front of the 

 eyes and feet show an excessively fine grej^ grizzle, without any 

 sign of yellow. Below bright " ochi'aceous" as in lohriah lohriah. 



Dimensions (recorded b}' the collector):- — -Head and bodj'^, 171; 

 tail, 134; hindfoot, 44; ear, 21. Skull:— Greatest length, 50-5; 

 •condylo-basal length, 45 ; nasals, 15 ; diastema, 13 ; cheek teeth, 8'5. 



Habitat. — Eastern Sikkim, the type from Sedonchen. 



Type. — An adult male. B. M. No. 15.9.1.125. Original num- 

 ber,'5775. Collected by Mr. C. A. Crump, on the 14th November, 

 1914, and presented to the National Collection by the Bombay 

 Natural Histor}" Society. 



With the Chindwin Collection we received two specimens (un- 

 foi'tunately both immature) from the Chin Hills which seem to 

 belong to the present race, but on the other hand there are two 

 specimens from Manipur, collected by Hume, which correspond the 

 one with lohriah lohriah and the other with lohriah hhotia. How- 

 ever until we have more material from Assam, there is little use in 

 speculating on the distribution of the two i-aces. 



3. — The Rats of the fdlvesceks group in Sikkim. 



Eijimys fulvescens was described by Gra}', from Nepal, in 1846. 

 Hodgson gave it the names caudatior and octomammis, but both 

 these names were later in date and moreover were nomina oiuda. 

 In 1863, Blyth described ^erf^o^w" on a specimen collected in Sikkim 

 by Dr. Jerdoii, his description is verj'- brief, and though his type 

 is not available to me for examination, his description so closely 

 parallels that of Gray that I have no doubt in considering it as 

 identical with fidvesoens, of which jerdjoni is therefore a synonym.
