■ ' Miller — Eleven Yen' Malayan Mmtse Deer. 33 



EkuU and teeth. — The skull and teeth, except for their markedly 

 smaller size, do not differ appreciably from those of Tragulus canescens 

 and T. napu. 



Measurements, — External measurements of type: total length, 503; 

 head and body, 4S8; tail vertebrae, 75: hind foot. 131 (117); ear from 

 meatus, 33; ear from crown, 28. Measurements of an adult female from 

 the type locality: total length, COO; head and body, 510; tail vertebrae, 

 90: hind foot, 131 (117); ear from meatus, 34: ear from crown, 30. 



Cranial measurements of type: greatest length, 105(110)*: basal length. 

 96.4 (105): basilar length, 90 (99); occipito-nasal length, 96 (99); length 

 of nasals, 32 (29); greatest breadth of both nasals together, 10 (12); dias- 

 tema. 9(9.6); zygomatic breadth, 44 (49); least interorbital breadth, 26 

 (30); mandible, 82 (89); maxillary toothrow (alveoli), 34.6 (40); maxil- 

 lary premolars (crowns), 17.4 (20); mandibular toothrow (alveoli), 39 (46); 

 mandibular premolars (crowns), IS (22). 



Weight. — Type, 2.5 kg.: adult female from type locality, 3 kg. 



Specimens examined. — Two, both from Pulo Sugi Bawa. 



Remarks. — This napu is so readily distinguished from all previously 

 known species by its small size, normal throat pattern and strongly yel- 

 lowish color that it needs no special comparison with any. The two 

 specimens are closely similar to each other except that the female is, as 

 usual, the larger. Some trifling variations in color have already been 

 noted. 



Tragulus flavicoIHs, sp. nov. 



Type. — Immaturef female (skin and skull) No. 115,505 United States 

 National Museum. Collected on Pulo Sugi, Rhio Archipelago, August 

 24, 1902, by Dr. W. L. Abbott. Original number 1957. 



Characters. — Much like Tragulus luteseens but yellower: nape stripe 

 absent, and dark throat stripes very slightly shaded with black. 



Color. — The general color is essentially as in Tragulus luteseens, but 

 the tawny element is everywhere more distinctly yellow, this most 

 noticeable on cheeks and neck. On nape the sprinkling of blackish 

 hairs is as inconspicuous as at sides of neck, so that there is no trace of 

 a dark median stripe. Throat pattern normal, the dark bands very 

 slightly more sprinkled with black than sides of neck. Collar very 

 narrow. The anterior yellowish bands are only about 15 mm. in length, 

 leaving the entire throat from chin to main throat stripes pure white. 

 Underparts as in the female specimen of Tragulus luteseens, but with 

 less blackish clouding. 



Skull and teeth. — I can detect nothing to distinguish the skull and 

 teeth from those of Tragulus luteseens. 



*Measurements in parenthesis are those of an adult male Tragulus 

 canescens from the Endau River, Johore. (No. 112,583.) 



fUterus contained a small embryo. Milk premolars still in place, 

 though much worn.
