bristles (somewhat resembling thin and narrow strips of whale bone)," 

 to Hystrix fasciculata, Shaw (v. H. macroura, Gervais), and he states 

 this to inhabit " Siam and the Malayan peninsula." It is doubtless the 

 species figured, eviendtly from life, by Gen. Hardwicke : but, if inhabit- 

 ing the Malayan peninsula, it must co-exist there with Ath. macroura, 

 (L.), apud Waterhouse, which has "the apex of the tail provided with 

 a large tuft of flat bristles, which are spirally twisted, and alternately 

 contracted and expanded." This Mr. Waterhouse gives doubtfully from 

 Sumatra ; and it is certainly the common Brush-tailed Porcupine of 

 the Malayan peninsula. In the Chittagong, Tippera, and Khasya 

 hills, there is a very similar race to the last, but with the spines 

 shorter and less coarse, excepting those of the croup, the ensemble 

 of the colouring greyer, and the enamel of the front-teeth pale 

 yellow instead of deep buff or orange-yellow. On minute comparison 

 of the skulls, the frontals of the Malayan race are seen to be somewhat 

 larger and more convex, while the parietals are proportionally smaller, 

 than in the Northern race : the palatal foramen, also, is narrower and 

 advances more forward in the former ; and the inferior lateral process 

 of the superior maxillary, forming the lower border of the great ant- 

 orbital foramen, is, in the Malayan race, given off anteriorly to the 

 position of the first molar, while in the Northern race it abuts directly 

 on the first molar. If distinct, it should bear the name spicigera 

 given to it by Buchanan Hamilton, who has excellently figured and 

 prepared a good MS. description of it, founded on a living pair 

 received from Chittagong. " They were brought," he was informed, 

 " from the hills ; and, so far as the donor (Mr. Macrae) understands, 

 their habits are pretty much the same as those of the Porcupine of 

 the plains. Both burrow in the earth, live upon roots, and are found 

 either in pairs or families." A specimen brought from Cherra Punji 

 by Mr. Frith corresponds exactly with Buchanan Hamilton's coloured 

 figure. 



Aves. 

 Of birds, the most remarkable are two new species of Garrulax, — 

 one of Suthora, — the Sibia gracilis, (McClelland and Horsfield,) 

 now first verified, — and Spizixos canifrons, nobis, J. A. S. XIV,
