than the cream -buff of Ridgway. The black clouding of the back i? 

 never in excess of the orauge-ochraceous. As if to compensate 

 for the relative lack of black on the body, the entire neck is of 

 this color, as in Tragulm bujiguranensis, its unifoi-mity scarcely 

 broken by an inconspicuous speckling due to the presence of a 

 narrow yellowish-brown annulation on many of the hairs. These 

 annulations are more numerous at sides of neck, but a few may be 

 found even along median line. Throat markings normal and 

 exactly similar to those of Tragulm pretiosus, excejjt that the dark 

 streaks are black, speckled with yellowish-brown to about the same 

 extent as sides of neck. Collar well defined and coarsely grizzled, it^* 

 light ground color nearly the same as that of sides of body though 

 a trifle more yellow. 



Skull and Teeth. — Except for their slightly greater size the skull 

 and teeth of Tragulus nigricollis do not differ appreciably from 

 those of T. pretiosus, though there appears to be a tendency toward 

 greater narrowness in the general form of the skull. 



3feasurements. — External measurements of type: Total length, 

 620; head and body, 540; tail vertebrae, 80; hind foot, 138; hind 

 foot without hoofs, 123. Weight, 4 kg. Average of five speci- 

 mens from the type locality: Total length, 647 (620-670); head 

 and body, 566 (540-590); tail vertebra, 81.6 (77-85); hind 

 foot, 142 (138-147); hind foot without hoofs, 126 (123-130). 

 Weight, 4.4 kg. (4-4.6). 



Cranial measurements of type: Greatest length, 116 (108);^ 

 basal length, 109 (101); basilar length, 104, (95); occipito-uasal 

 length, 103 (99); lengdi of nasals, 34 (33.6); diastema, 11 

 (10); zygomatic breadth, 50 (49); least interorbital breadth, 31 

 (29); mandible, 92 (88); maxillary toothrow (alveoli), 40 (36); 

 mandibular toothrow (alveoli), 45.4 (42). 



Specimens Examined. — Five, all from Sinkep Island. 



Remarks. — In general appearance Tragulus nigricollis more 

 closely resembles the black-necked T. bunguranensis than it does 

 T. pretiosus. It is readily separable from the Bunguran animal by 

 its somewhat paler general coloration and by its normal throat 

 markings. The series shows no individual variation worthy of 

 note, except that in one specimen (cf, No. 113,124) the white 



* Measurements in parentheses are those of the type of IVagulus 

 pretiosus.
