DESCRIPTIONS OF NEW SPECIES OF MAMMALS 

 FROM THE ANDAMAN AND NICOBAR ISLANDS. 



The following descriptions of new species of Mammals are extracted from 

 a paper by Mr. Gerrit S. Miller, Jnr., published in the Proceedings of the 

 United States National Museum (Vol. XXIV, pp. 7.51 — 795), on the collection 

 made by Dr. W. L. Abbott and Mr. 0, B. Kloss, who visited the islands 

 during the months of January, February and March 1901. 

 StJS NicoBARicus, new species. 

 Type.—Yoxmg 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. Colour entirely black. Tail covered with a sparse, nearly uni- 

 form 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 andamanensis, and is much less 

 harsh than that of Sus cristatus. The diameter of the individual bristles of 

 both back and mane is scarcely more than half that of hairs from corre- 

 sponding 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 cristatus. At middle of back the bristles of the crest are about 

 70 mm. in length, while those bordering it barely reach a length of 50 mm. 

 The crest, however, owes its distinctness to the greater crowding of the 

 bristles of which it is composed, as compared with those of the surrounding 

 parts. As in Sus andamanensis, the skin is plainly visible through its scant 

 covering of hair everywhere except in the region occupied by the mane and 

 crest. The cheeks are more hairy than in Sus andamanensis. The tail is 

 hairy throughout except at tip. At base the hairs, which are much softer 

 than the bristles of the back, are rather inconspicuous, but near middle they 

 increase in number and in length, and form a straggling brush, the longest 

 hairs of which are 150 mm. long. 



Colour. — The colour is black throughout, with a faint brownish wash on 

 dorsal crest. Hoofs rather dark horn colour. In the type the hind feet are 

 albinistic between hoof and hock, the light colour involving the hoofs as well 

 as the hair. 



Skull. — The skull of Sus nicobaricus, though distinctly larger than that of 

 S. andamanensis, shows no approach to the dimensions of that of S. cristatus. 

 In form it differs from the skull of Sus andamanensis chiefly in the greater 

 angle formed by the surface of the forehead with that of the rostrum, and 

 in the larger, more inflated audital bulte. The zygomatic arch as a whole is 

 more heavily built than in Sus andamanensis, and its horizontal surface is 

 broader posteriorly. 



As compared with the skull of Sus cristatus from Tenasserim, that of 

 S, nicobaricus shows numerous differences in form. Most conspicuous among
