Miller — MainmaU from Lankawi and Biitauf/ Islands 191 



(lull Inilf-yellow heavily sprinkled with dark brown. Ventral svirface 

 dull, ijale, bufT, stroii<;ly suffused with drab-gray, particularly along 

 median line. Chin and throat usually dull huffy white scarcely tinged 

 with gray. 



Skii/L — The skull is similar to that of j¥?/.'* tamhelanicus except that 

 the audilal bulhe are very noticeably larger and less depressed on the 

 outer side. Teeth as in Mtn- fambclnniciiM, that is. like those of 3fnx 

 Uile.vandrini!.s', only larger. 



3/(vy,vw/v///6'« /.v. —External measurements of type: total length, 406; 

 head and body, 203; tail vertebrae, 203: hind foot, 41; hind foot without 

 claws, 38. Average of seven specimens from the type locality: total 

 length, 380 (373-406); head and body, 196 (184-203); tail vertebra?, 190 

 (184-203); hind foot, 40 (38-41.5): hind foot without claws, 38 (35-39). 

 An adult male from Pulo Kawi measures: total length, 409; head and 

 bod}', 203; tail vertebne, 196; hind foot, 39; hind foot without claws, 36. 



Specimenfi examined. — Ten (three in alcohol) from Pulo Adang, and 

 three from Pulo Rawi, Butang Islands. 



Remarks. — The close resemblance of this species to ilf!/.s tamhdairinix, 

 and its unlikeness to the small Mus 'ale.vafidrinus' of the adjacent main- 

 land suggest that the two large animals are less closely related to the 

 latter than I at first supposed Mu.-i fiDiibekmicus to be. While of the 

 same general form as the roof rat they are heavier animals with coarser 

 more shaggy fur. 



Mus cremoriventer subsp. '.' 



Two specimens (one in alcohol) from Pulo Lankawi and a third from 

 Pulo Adang differ from true Miin rrcmoripenter in a strong yellowish 

 suffusion of the entire pelage. As they were taken at practically the 

 same season as the original specimens of 3f. crcmorwenter there is little 

 probabilily that the differences are due to individual variation. With- 

 out further material, and particularly in the absence of series of the 

 yellowish Mux flanventer from the Anambas, it seems unwise to attempt 

 1(1 tlefine the present race. 



Ratufa melanopepla Miller, 

 (ine specimen. Pulo Lankawi, December 9, 1899. 



Sciurus concolor Blyth. 



Two specimens from Pulo T^ankawi and three from Pulo Adang. They 

 ayree in all essential characters with skins from Trong, Lower Siam, but 

 whether the same as the trvie concolor of Malacca it is at present impos- 

 sible to determine.
