miller] seventy new Malayan mammals 3 



Skull and teeth. — The skull is very large and the nasals are 

 unusually long, but otherwise I do not detect any tangible cranial 

 characters. Teeth large, particularly the upper premolars. 



Measurements. — External measurements of type: total length, 

 680; head and body, 595; tail vertebrse, 85; hind foot, 145 (130) ; 

 ear from meatus, 36.6; ear from crown, 30; width of ear, 24. 



Cranial measurements of type: greatest length, 120 (116) ;^ basal 

 length, 112 (108) ; basilar length, 105 (102) ; occipito-nasal length, 

 no (105) ; length of nasals, 40 (36) ; greatest breadth of both nasals 

 together, 13 (13) ; diastema, 15 (12.4) ; zygomatic breadth, 54 (48) ; 

 least interorbital breadth, 32 (30.4) ; mandible, 95 (91) ; maxillary 

 toothrow (alveoli), 41 (39) ; maxillary premolars (crowns), 22 

 (20.4); mandibular toothrow (alveoli), 47 (45); mandibular pre- 

 molars (crowns), 23.4 (20). 



Specimens examined. — Four, all from the Batu Islands, one from 

 Tana Masa, the rest from Tana Bala. 



Remarks. — Unfortunately the type is the only adult in the collec- 

 tion. The immature individuals differ from it in the presence of a 

 grayish buff wash on middle of belly, a character which is probably 

 individual rather than due to the difference in age. The species is 

 easily recognizable by the forward extension of the black neck area, 

 combined with the normal throat pattern. 



TRAGULUS RUSSULUS sp. nov. 



Type. — Adult male (skin and skull), No. 121,701, United States 

 National Museum. Collected on Tana Bala, Batu Islands, Sumatra, 

 February 8, 1903, by Dr. W. L. Abbott. Original number, 2249. 



Characters. — A member of the kanchil group similar to Tragulus 

 russeiis of the Banjak Islands, but upper parts not as dark, belly 

 with less extensive yellowish suffusion, and throat pattern always 

 normal. Skull and teeth not so large as in Tragulus russeus. 



Color. — Type : general color above orange-ochraceous darker 

 than that of Ridgway, the neck and outer surface of limbs brighter 

 than body. The hairs of the back are tipped with black, forming 

 a slight, uniform, dark clouding, much less pronounced than in 

 Tragulus russeus. On shoulders this shading deepens abruptly into 

 the black, slightly grizzled neck stripe. Crown a grizzle of dusky 

 brown and buff. Cheeks dull buff. A faintly indicated buffy stripe 

 borders upper margin of very ill-defined dark loral stripe. Ears 

 blackish. * Throat pattern normal, the dark stripes and collar orange- 



* Measurements in parenthesis are those of an adult female paratype (No. 

 113,120) of Tragulus nigricollis.
