black, in certain lights showing- faint brownish ti])s, which become 
noticeable on the mane and crest only. The caudal tuft is also tinged 
with brown. As there is essentially no hair in the region it would 
occupy, the light malar streak of 6\ crlstatus is absent. 
Aside from its strikingl}^ smaller size the skull of Sus andainatieiisis 
shows no distinct character to separate it from that of S. cristatiis. 
The teeth of the one specimen secured by Dr. Abbott are so worn that 
the enamel pattern is largely obliterated, but that which remains shows 
no indication of less complexity than in Siis o'istatus. The length of 
the hinder molar, both above and below, is equal to that of the two 
preceding teeth together. The cranial measurements of this specimen, 
together with those of a young adult skull of Sus crlstatus from Tan- 
jong Badak, Tenasserim, the latter in parenthesis, are as follows: 
Occipito-nasal length (median), 256 (370) mm.; basal length, 220 
(320); basilar length, 215 (310); length of nasals, 123 (185); width of 
both nasals together posteriori}^, 25 (40); median length of Ijoii}' palate, 
153 (220); width of bony palate at middle of second molar, 27 (38); 
distance between tips of postorbital processes, 81 (111); least interor- 
bital breadth, 55 (85); zygomatic breadth, 114(148); occipital breadth, 
52 (76); occipital depth, 95 (130); least depth of rostrum between 
canine and incisor, 29 (46); mandible, 190 (270); depth of mandible 
through coronoid process, 90 (120); depth of ramus at front of first 
molar, 36 (47); maxillary toothrow to front of canine (alveoli), 107 
(154); mandibular toothrow to front of canine (alveoli), 117 (166); 
crown of first upper molar, 10 by 14 (17 by 15); crown of second upper 
molar, 17 by 14 (23 b}^ 19); crown of third upper molar, 25 by 16 (37 
by 21); crown of first lower molar, 13 by 10 (16.4 by 11); crown of 
second lower molar, 16 bj^ 14 (21.6 by 15); crown of third lower molar, 
27 by 13.6 (40 by 17). 
SUS NICOBARICUS, new species. 
7?/y>'.— Young adult male (skin and .skull). No. 111794, U.S.N.M. 
Collected on Great Nicobar Island, Nicobars, March 13, 1901, by 
Dr. W. L. Abbott. Original number, 930. 
Characters. — Like Sus andamanensis^ but slightly larger, and with 
much larger teeth. Color entirely black. Tail covered with a sparse, 
nearly uniform growth of long black hairs. 
Fur. — The fur throughout consists of bristles with no admixture of 
softer hairs. In texture it resembles that of Sus andamaneoisis., and 
is much le.ss harsh than that of Sus crlstatus. The diameter of the 
individual bristles of both back and mane is scarcel}^ more than half 
that of hairs from corresponding regions in the mainland animal, and 
is apparently a little less than in the Andaman pig. Mane and dorsal 
crest well developed, though less so than in Sus crlstatus. At. middle 
of back the bristles of the crest are about 70 mm. in length, while
