630 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. XXXIV. 
Specimens examined.—Nine from the Little Siak River, four from 
Kompei, two from Sungei Mandau, two from Makapan, and four 
from Pulo Penjalei. 
Remarks.—The Traguli of the kanchil group from the Siak region 
in eastern Sumatra are quite variable. Most of them are like typical 
kanchil except with larger feet, others of them, one from Kompei, one 
from Sungei Mandau, and especially the two from Makapan, are 
almost identical in point of color and size with the 7ragulus from the 
neighboring islands of Rupat, Padang, Bengkalis, Tebing Tinggi, 
and Rangsam. The 7ragulus from Pulo Penjalei, an island at the 
mouth of the Kateman River, is singularly enough clearly referable 
to TZ. kanchil longipes both in point of size and coloration. 
TRAGULUS FULVICOLLIS, new species. 
Type.—Skin and skull of adult female, Cat. No. 143519, U.S.N.M., 
collected on Pulo Bengkalis off east coast of Sumatra, March 27, 1906, 
by Dr. W. L. Abbott. Original number 4765. 
Diagnostic characters—A large member of the Tragulus kanchil 
group, somewhat like 7ragulus ravus Miller,* from the Malay Penin- 
sula, but much larger and more richly colored especially about the 
neck and forelegs; differs from 7. kanchil in its larger size and 
lighter color. 
Color—Type: Upper parts and sides of body a mixture of light 
and dull orange-buff and black, the black slightly in excess along 
the middle line of the back, both colors equally prominent along the 
sides but the black gradually disappearing as the belly is reached 
so that next to the white of the underparts no black is mixed in with — 
the dull orange-buff. Sides and top of neck tawny-ochraceous with 
no admixture of black except for a narrow (15 mm. wide), ill-defined 
nape stripe which gradually blends in with the colors of the middle 
line of the back. The tawny-ochraceous of the neck gradually blends 
in with the dull orange-buff of the body. Top of head a mixture of 
black and tawny-ochraceous, the former color in excess. Sides of 
head similar to sides of neck but duller. Underparts generally 
white. Throat pattern normal, the collar and median line of belly 
(5 mm. wide anteriorly, 30 mm. posteriorly) a hght ochraceous or 
dull orange-buff, the A in front of collar similar in color but faintly 
lined with black. Inner sides of legs white; outer sides tawny-ochra- 
ceous, bright and clear on the forelegs, duller and with a slight ad- 
mixture of black on the hind legs. Tail above dull tawny slightly 
admixed with black, below and at the tip white. 
Variation in the series: The series as a whole does not show much 
variation in respect to color. Some of the specimens run slightly 
lighter than the tvpe. The extent of the black on the top of head
