iug species were trapped iu the jungle by natives and brought in 

 considerable numbei's for sale. 



The series from the two islands show very little individual varia- 

 tion. The constancy of coloring iu this species as compai'ed with 

 the extreme plasticity of the napu is very striking, particularly 

 when it is remembered that the ranges of the two coincide, and 

 that the animals are everywhere exposed to like conditions of envi- 

 ronment. 

 Tragulus pretiosus sp. nov. 



1900. Tragulus napu Miller, Proc. "Washington Acad. Sci., II, p. 

 227, August 20, 1900. Not of F. Cuvier. 



Type.— AcMt male (skin and skull), No. 113,031 United States 

 National Museum. Collected on Liuga Island, South China Sea, 

 August 27, 1901, by Dr. W. L. Abbott. Original number 1,238. 



Characters. — A richly colored yellowish member of the napu 

 group. Throat markings normal, the anterior white stripes not 

 elongated or margined with black, the dark stripes brown. Neck 

 yellowish-brown with narrow median black stripe. Belly heavily 

 shaded with yellowish-brown. 



Color. — Upper parts orange-ochraceous, darkening toward ochra- 

 ceous-rufous on sides of neck and outer surface of legs, and light- 

 ening to orange-buff on sides of body, the hairs everywhere ecru- 

 drab at base and black at tip. The black tips are most conspicuous 

 over middle of back, where they produce a heavy dark shading 

 slightly in excess of the orange-ochi-aceous. On sides of body they 

 are much less noticeable, and on sides of neck and head and outer 

 surface of legs would readily pass unnoticed. Crown and median 

 line of neck black, the latter noticeably sprinkled with ochraceous- 

 rufous. Throat markings normal, the hairs of the dark bands 

 blackish at base and heavily annulated with dull ochraceous-rufous. 

 Collar narrow but distinct, its color like that of sides of body. 

 Under parts behind throat markings mostly orange-buff mixed with 

 drab. There is always, however, a pure white patch on chest 

 between front legs, and another iu hypogastric region between hind 

 legs, the former generally continuous with narrow white line on 

 inner side of leg, the latter always so. The two white patches 

 occasionally spread toward each other so that they meet along 

 median line. Tail rather dull ochraceous-rufous above, pure white 

 below and at tip.
