torque or collar separating the ferruginous sharply from the purer 

 ashy of the breast ; an ill defined whitish streak with black specks 

 on each side of the throat, and similar but more rufescent supercilia. 



Bill black ; hides red brown ; orbits dull lake red ; legs red. 

 Length 1(H to 11 inches ; extent 19 ; wing 5| ; tail 2 ; tarsus If. 



The female has the dusky bars and undulations well developed, 

 and the throat is more ferruginous than the female of the last, but 

 otherwise there is little difference. 



The rufous-throated Hill-partridge was discriminated by Blyth 

 from specimens sent from Darjeeling, and we are ignorant of 

 its range west of Sikim. It probably, hoAvever, extends into 

 several of the hill ranges of Assam and Sylhet, for I procured it on 

 the Khasia Hills. Its habits, voice, &c, are very similar to those of 

 the previous species, from which it is not generally distinguished, 

 but the natives of Sikim discriminate them, and have different 

 names for them. The present species is found at lower altitudes 

 than the former one, occurring chiefly from 3,000 to 6,000 feet of 

 elevation, or rather more. Neither of these Partridges are readily 

 obtainable by the sportsman at Darjeeling, owing to the density 

 of the forest. Now- and then dogs will put up a covey at which a 

 chance shot may be had ; but in general they can be best pro- 

 cured by imitating their whistle, and thus decoying them within 

 short range of the gunner. 



Arhoricola atrogularis, Blyth, is very closely allied to A. tor- 

 queola, but differs in the male not having a chesnut head. It 

 appears to be P. olivacea of Buch. Hamilton, and is found in the 

 Tipperah Hills and Chittagong. A. intermedia, Blyth, occurs in 

 Arrakan ; and A. brunneo-pectus, Tickell, is f rom Tenasserim. This 

 species has the wings strongly marked with chesnut. One species, 

 A. sphenura is stated to occur in China. To the same group belong 

 Perdix personata, Horsfield, and P. javanica, Gmelin, both from 

 Java. Peloperdix, Blyth, founded on Perdix charltoni of Penang, 

 is a distinct though affined form ; and it appears to me that 

 P.punctulata, Gray, figured in Hardwicke's 111. Ind. Zool., is either 

 the same bird as P. charltoni, or some nearly related species, 

 perhaps P. chlorojyus, Blyth. Caloperdix, Blyth, founded on the 

 Tetrao ocellatus^ Raffles, (Perdix ocirfea, Temminck) is a very beauti-
