3rd subgenus, Horeites, mihi. 



Bill shorter than the head, quite straight, cylindric, feeble, di- 

 stinctly notched ; nares basai, ovoid, covered with a membranous 

 scale ; legs and feet stronger than in either of the above, and more 

 suited to ground action ; tarse high, strong, and heavily scaled, as in 

 Orthotomus ; toes longer, more ambulant, with the laterals equal and 

 centrai elongated ; rietus ąuite smooth ; M'ings and tail as in Prinia, 

 or as in Orthotomus. Inhabits the northern region near the snows, 

 dweUing in brushwood and being much on the ground. 



Ist species, H. pollicaris, mihi. — Remarkable for its small wing3 

 and tail and large hind digit, the tail being equal in length to the 

 closed wing, which is perfectly rounded and short, as in Prinia. 

 Above olive-brovvn ; below and the eyebrovv pale yellow ; bill sordid 

 comeous grey ; legs fleshy grey. Length, 3^ inches ; bill, -^ ; 

 tail, \^ ; u-ing the šame ; tarse, J-| ; centrai toe and nail, \^ ; hind, ^. 



2nd species, H. schistilatus, mihi. — Has an ampler wing and tail 

 than the lašt and a smaller thumb ; its wing is as large as in Ortho- 

 tomus, and its tail broad and faa-shaped, hke Prinia. In colours very 

 ' likę brunnifrons, but distinguished by its broader ampler tail, larger 

 wing, and shorter Regulus-like bill. Above uniform olive-brovvn ; 

 laterally pale slaty and below pure white ; cap clear brown-red or 

 chestnut. Dwells near the snows, likę the last-named. Length, 

 4^ inches ; bill, ^ ; tail, 2^ ; wing, 1^ ; tarse, | ; centrai toe and 

 nail, ^ ; hind, ^. 



Allied to the lašt two species are some more Cachar birds of very 

 similar manners and plumage, distinguished by a compressed bill, 

 which is raised betvveen the keeled nares, as in our Stachyris, and 

 by the inner toe and nail of their strong ambulant feet being longer 

 than the outer toe and nail. Some have the tarse smooth and the 

 tail more or less scansorial, that is, cuneate in form and rather rigid 

 or worn ; these I call Tribura. The others have the tarse scutellate 

 and rather longer, and the tail broad and fan-shaped, and not at all 

 rigid or worn ; these I stj'le Heromis, though they hardly deserve 

 subgeneric separation. 



Genus Tribura, mihi. 



Bill to gape equal to head or less, straight, cylindric, compressed ; 

 at base higher than broad, and having the ridge raised and keeled 

 between the oval apert nares ; tip of upper mandible scarcely inclined, 

 but distinctly notched ; rietus smooth ; -svings short and feeble, but 

 not much or eąually gradated ; first two quills conspicuously gra- 

 dated, three next subequal and longest ; tail more or less elongated, 

 and gradated throughout, rather cuneate than fan-shaped, and some- 

 what rigid or worn ; tarse stout, smooth, longer than the mid toe and 

 nail; toes and nails simple, compressed, inner fore with its nail ex- 

 ceeding the outer fore, centrai elongate, hind least; nails acute. 



Type, T. luteoventris , mihi. 



Tribura luteoventris, mihi. — Above olive-brovvn, vvith a luteous 

 lustre ; belovv lutescent laterally and albescent centrally ; a jpale line
