SCIENTIIIC RESULTS OF THE MAMMAL SURVEY. 29 



MiLLARDIA KATHLEENS, Sp. 11, 



Byley's Soft-furred Eat. 



A light coloured Millardia, with white tail tip and only — 2=4 

 mammae. Size abont equal to that of the largest of the known 

 species. 



General colour above, pale sandy fawn, not unlike that of M. 

 meltada ixdlidior, Rj^ley. Flanks and regions round eyes brighter 

 fawn. Undersiirface pale greyish white, the bases of the hairs 

 generally pale slaty, but those on chin and in the inguinal region 

 white to their bases. Ears fairlj^ large, greyish, differing little in 

 colour from the general tone. Hands and feet white ; soles with 

 only four pads, the normal murine fifth and sixth completely absent. 

 Tail varying from rather shorter to rather longer than the head and 

 body, thinly haired, not pencilled, greyish brown for the greater 

 part, sometimes the whole of its length, white below and terminally ; 

 about 12 rings to the centimeter. Mammse 0-2=4. 



Skull on the whole very similar to that of M. meltada. Nasals 

 narrow. Superorbital ridges well marked. Interparietal more 

 triangular, with a greater antero-posterior diameter. Anterior 

 palatine foramina not elongated. Bullae very large, larger than in 

 any of the known species either of Millardia or the other allied 

 genera. 



Dimensions of the type (measured in the flesh). — Head and body 

 145 (range 131-166); tail 148 (130-159); hindfoot 27 (26-30); 

 ear 21 (20-23). 



Shdl. — Greatest length 35-4; condylo-incisive length 33-2; 

 zygomatic breadth 17-7; nasals 14-5; interorbital breadth 5; 

 interparietal 5*3 x 9*5 ; palatilar length 16*5 ; palatal foramine 8-6 ; 

 upper molar series 5*7. 



Hah. — Dry zone of Burma. Most of the specimens, including 

 type, from Pagan : a few from Mt. Popa. 



Ty^ye. — Adult female. B. M. No. 14.4.3.5. Original number 

 4095. Collected at Pagan, 16th October 1913. 



This Burmese rat forms a very distinct new species, as all the pre- 

 viously known members of Millardia have 2-2=8 mammae, normal 

 sized buUge, and generally some trace of a fifth hindfoot pad. They 

 are also all inhabitants of the Peninsula of India, not extending 

 east of the Bay of Bengal. 



I have named the species in honour of Miss Kathleen Ryley, to 

 whom the Survey is much indebted for the work she has done on its 

 collections during the temporary absence of Mr. Wronghton. I 

 venture to hope that on her return to England she will again 

 take up the subject of Indian mammalogy, with the help of the 

 increased material which the Bombay Society's Survey is bringing 

 tog'ether.
