40 Miller — Eleven New Malayan Mouse Deer. 



ochraceous a little grizzled by blackish hair tips. Upper surface of tail 

 ochraceous-rufous washed with dark brown. Nape band broad and 

 distinct but not sharply defined at sides, black with a few yellowish 

 specks, Crown dark brown, faintly grizzled. Throat markings normal, 

 slightly darker than in Tragulus kanchil. Underparts strongly washed 

 with orange-buff along median line, this wash usually spreading toward 

 sides and often separating white of chest from that of inguinal 

 region. While there is some variation in this character the suffusion is 

 always more extensive than in the Sumatran animal, so that when series 

 are compared the difference is very noticeable. 



Skull and teeth. — The skull and teeth do not differ from those of 

 Tragulus kanchil. 



Measurements. — External measurements of type: total length, 540: 

 head and body, 470; tail vertebra, 70; hind foot, 125 (113); ear from 

 meatus, 32; ear from crown, 28. Measurements of an adult male from 

 the type locality: total length, 528; head and body, 450: tail vertebra 1 , 

 78; hind foot, 120 (108.5). Skull of type: greatest length, 97; basal 

 length, 90; zygomatic breadth, 42. 6; diastema, 10.8. 



Weight. — Type, 2.27 kg. Adult male from type locality, 1.8 kg. 



Specimens examined. — Nineteen: five from Sinkep Island and fourteen 

 (three in alcohol) from Linga Island. 



Remarks. — In a certain degree this species is intermediate between 

 the dull, dark, Tragulus kanchil of Sumatra, and the very bright T. 

 natunce. It is readily distinguishable from both of the related species. 



Tragulus rubeus, sp. now 



Type. — Adtdt female (skin and skull) No. 115,522 United States Na-
