Nos. 1510 to 1512. Arboricola, Hodgson. There are three 

 distinct races or species of this genus which require discrimination. 



No. 1510. A. torq,ueola ; Perdix torqueola, Valenciennes : P. me- 

 gapodia, Temminck ; P. olivacea, Gray. The common Himalayan spe- 

 cies, from Simla to Darjiling ; with the crown and ear-coverts of the male 

 ferrugineous, passing down the sides of the neck ; lores, supercilia, and 

 throat black, the lateral and lower feathers of the last white-margined ; 

 a broad and defined white torque or gorget above the breast, and some- 

 times (but not always) a small white streak from the base of the lower 

 mandible. Females have the torque ferruginous, and the throat less 

 deep ferruginous spotted with black more or less ; the crown and ear- 

 coverts dusky olive-brown, and a pale rufescent supercilium speckled 

 with black : the black bars and spots are also more developed on the 

 upper-parts generally ; and the ferruginous torque has never a black 

 border. This is the only race we have seen from the N. W. Himalaya ; 

 and at Darjiling we are informed that it inhabits a loftier range of 

 elevation than the next. 



No. 1511. A. rufogularis, nobis. Rather smaller, on the aver- 

 age ; throat and front and sides of neck of the male deep ferruginous, 

 with small black specks on the throat and a black margin to the ferru- 

 ginous more or less developed, separating it from the pure ash-colour 

 of the breast ; an ill-defined white streak with black specks on each 

 side of the throat, and similar but more rufescent supercilia. The bars 

 on the upper-parts are generally quite obsolete. In the females these 

 are well developed ; and unless the throat may be of a deeper ferrugin- 

 ous, there seems to be no difference between this sex and the female of 

 A. torqueola. The present race would appear to be common in the 

 vicinity of Darjiling. 



No. 1512. A. atrogularis, nobis. Breast and .flanks of the male 

 pure ashy without any rufous, but a few small white spots on the 

 flanks ; abdominal region pure white ; crown of the same olive-green 

 as the back, passing to ashy on the forehead ; supercilia black margined 

 above with white, and lores black bordered below with a broad white 

 streak from the base of the lower mandible ; chin also white in some, 

 but in general the chin and throat are deep black, bordered below by 

 an undefined white gorget, and the upper-part of the breast has large 

 black drops below the white gorget. The upper-parts are more dis-
