ing towards the tip, which is strongly ernarginated, and forms a dis- 

 tinct hook, overhanging the extremity of the lower mandible ; nostrils 

 oval, pierced in the fore-part of the nasal membrane ; wings and tail 

 graduated, the first primary two-fifths the length of the fifth, which 

 is equal to the sixth and seventh and longest: feet formed for perch- 

 ing, the tarse rather longer than the middle toe with its claw, and the 

 claws but moderately curved: tail elongated. 



G. rufuhis, Nobis. Length about nine inches, of which the tail is 

 four and three-quarters, and bill to gape above seven-eighths of an 

 inch ; wing three inches and a half; and tarse an inch and one six- 

 teenth. Colour of the upper-parts uniform olive-brown : and the head 

 and entire under-parts probably wholly ferruginous; but the only 

 specimen examined is a partial albino, having the head and under- 

 parts white, with a few ferruginous feathers intermixed: bill horn- 

 coloured, the upper mandible dusky above, and the lower pale; and 

 feet light brown : under-surface of the wings pale fulvescent, which 

 also margins the basal portion of the inner webs of the large alars : tail 

 much graduated, its feathers more or less tipped with albescent ; ricto- 

 rial bristles black. Received from Darjeeling. 



Orthorhinus, Nobis, n. g. General structure of Pomatorhinus, but 

 the plumage still more lax and open, the wings more bowed or hol- 

 lowed, and the feet more decidedly adapted for progression on the 

 ground, having the claws larger and straighter : the bill is less elongat- 

 ed than in the more typical Pomatorhini, and is much less compressed, 

 its upper mandible shewing scarcely more than an indication of a 

 curve, and the gonys of the lower mandible ascending posteriorly to the 

 junction of its rami, by which a distinct angle is there produced. 



O. hypoleucos, Nobis. Length about ten inches, of which the tail mea- 

 sures four ; wing four inches and a quarter ; bill to gape one and a half; 

 tarse rather more ; hind toe and claw an inch and a quarter. General 

 colour fulvescent olive-brown above, the lower parts white, with traces 

 of dusky terminal spots on the breast; streak backward from behind 

 the eye, and the sides of the neck posterior to the ear- coverts, bright 

 fulvous ; sides of the breast ashy, with white centres to feathers : the 

 bill dusky, a little whitish at tip, and beneath the lower mandible: 

 legs pale : the feathers of the crown a little squamose. Inhabits Arracan. 



Another Indian genus referrible to the same great series, is Pellor- 

 nium of Swainson, v. Cinclidia, Gould ; and the only species — P. rufi.
