which abounds in Arakan and the Tenasserim provinces, merely differs 

 from the common T. ferruginea, Raffles, of the Malayan peninsula, 

 in being less deeply tinged (and often not at all so) with maronne on 

 the upper-parts ; the colouring being much as in T. javanica, but 

 still having a decided rufous cast as compared with this little species 

 which likewise is common about Malacca and Singapore, though 

 unnoticed in Dr. Cantor's list of the mammalia of the Malayan penin- 

 sula. We cannot regard T. Belangeri as distinct from T. ferru- 

 ginea ; and we have not previously seen it from so northern a 

 locality as Cherra Punji, though it probably also inhabits Asam. The 

 species of Central and Southern India, T. Elliott, Waterhouse, is a 

 much larger animal, equal in size to T. tana (v. cladobates speci- 

 osus, Wagner), of the Archipelago ; and the only remaining species of 

 this genus hitherto discovered is the strongly marked T. murina, 

 (Diard), from. the Western Coast of Borneo, figured by Dr. S. Muller 

 and M. Temminck. 



Rhizomys pruinosus, nobis, n. s. So far as can be judged from 

 external characters, this quite resembles Rh. radius, Hodgson, of the 

 vicinity of Darjiling, and Rh. castaneus, nobis, J. A. S. XIT, 1007, 

 of Arakan, except in being very differently coloured : the fur being 

 uniformly dusky-slate above and below, with hoary tips, which latter 

 are of somewhat coarser texture ; on the belly there is a slight silvery 

 shade. All three differ from Rh. sumatrensis (v. cinereus, McClel- 

 land,) of the Tenasserim provinces and Malayan peninsula, in being 

 much less robust, having a much shorter tail, and a dense coat of fine 

 soft fur instead of a thin coat of bristly fur; but their structural 

 characters are essentially the same. An example of the present race 

 was long ago forwarded to the Society from Cherra Punji by F. Skip- 

 with, Esq., C. S. ; but we deferred describing it until seeing additional 

 specimens. Mr. Skipwith's specimen having old and faded fur is 

 much browner and less slaty than those obtained by Mr. Frith in 

 newly renovated pelage ; but the hoary tips are conspicuous in all. 

 It is extremely common at Cherra Punji. 



Atherura macroura ? (L. ; nee Hystrix fasciculata, Shaw) : 

 Hystrix spicifera, Buch. Ham., MS. The different Asiatic species 

 of this genus remain to be fully discriminated. Mr. Waterhouse 

 refers the Siamese race, with a terminal tail tuft of "long flattened
