of the Genus Pomatorhinus. 143 



others dark smoky grey ; these latter I take to be be very old 

 birds : spec, descr. mus. Tweeddale, Himalayas. In some ex- 

 amples the rusty sides of the breast almost meet, and in one 

 (from Darjecling) form a pectoral band a quarter of an inch 

 broad; and, further, some specimens have a brown streak 

 along the rami of the mandible ; but in others this is absent. 



Iris pale yellowish white ; bill horny green, darker along 

 ridge of upper mandible ; legs and claws fleshy {Beavan) . 



Wing 3"9 inches, bill from gape 1*4 to 1*6, tarsus l'4to 1*5, 

 tail 4*5. 



Hab. Himalayas [Jerdon), Tenasserim {Hume). 



This species belongs, as the last, to a group which 

 ought perhaps to be generically separated, as has been sug- 

 gested by other authors. All the species of it (six in number, 

 viz. P. hypoleucus, Bl., P. erijthrogenys, Vig., P. m' dell audi , 

 Jerd., P. erythrocnemis, Gould, and P. swinhoei, Dav. et 

 Oust.), have the bill dark-coloured, rather more curved than 

 in typical Pomatorhinus, and very large.

Pomatorhinus gravivox, David, Ann. Sc. Nat. (5) xviii. p. 2 

 (1873) ; D. & O. Ois. de la Chine, p. 183, pi. 49. 



Allied to P. erythrogenys, Vigors ; but differing in its much 

 smaller size, and the forehead, ear-coverts, and under tail- 

 coverts only being rusty brown, the flanks olive-brown, throat, 

 middle of the belly, and breast being white, the latter with a 

 distinct large triangular brown spot on each feather, and a 

 brown moustachial streak along the rami of the mandible. 

 Spec, descr. ex Assam : mus. Godwin- Austen. 



In some specimens a few of the white feathers of the 

 breast are very faintly tinged with rusty, forming a rudimen- 

 tary band, which is very highly developed in one specimen 

 only of P. erythrogenys above referred to. 



Irides ochre; legs and feet fleshy grey [Godwin- Austen) . 



Wing 3*3 inches, bill from gape 1'2, tarsus 1"35, tail 38 

 (Khasia).
