180 ORNITHOLOGY OF NEPAL. 



bowed wings and tail — the former short and rounded — the latter more or 

 less elongated and gradated on the sides. 



Tmialia and Prinia seem to be obviously sub-genera of Pomatorhinus, 

 ^ both distinguished from the generic type by a shorter and less arched bill, 

 and by the rigid spinous character of the shafts of the plumage, more espe- 



■ cially on the head and neck. In both sub-genera the legs and tail are 

 . rather longer, and the tarsi more heavily scaled than in the generic type. 



The last member or tail consists, in Timalia, of twelve rectrices, as in 

 Cinclosoma. But in Timalia they are broader and more gradated to the 

 ' . sides; in Prinia narrower, 10 only in number, and strongly gradated 



■ throughout, with yet greater accession of length. 



The most typical species of Pomatorhinus I consider to be Erythro- 

 genys Gouidii (1831), 'Ferrtigilatus, nobis. (MS. 1826.) 

 The following is a detail of its form and colours :

Species 1st. Erythrogenys Gouldii.— Ferrugilatus, or Rusty-sided, 

 nobis. 



Form. Bill a third longer than the head, perfectly entire, conspicuously 

 arched throughout, strong, hard, slender, much compressed with broad 

 convex ridges and plane vertical sides ; upper mandible nearly solid, espe- 

 cially towards the point, lower somewhat scooped ; tomiae before the nares 

 trenchant erect, scarpt and sub-locked, free and level with the palate towards 

 the tips, which last are obtuse and rather unequal in length ; carination of 

 the culmen restricted but distinct. Plumes of the forehead and head soft ; 

 those of the lares and chin subsetaceous. Tongue somewhat elongated, 

 simple, narrow, cartilaginous ; its tip bifid or jagged. Wings not exceeding 

 the base of the tail, perfectly rounded, bowed ; 5 first quills regularly gra- 

 dated in a diminishing ratio ; 6th usually longest, the rest insensibly 

 decreasing ; the vanes of all, broad and entire. Tail sub-elongated, not equal 

 to the body and neck, consisting of twelve sub-bowed, moderately broad 

 plumes, of which the 6 centrals are even, and the 6 laterals gradated, but
