cruentatum, D. concolor, D. chrysochlorum, &c. ; 3, Myzanthe, Hodg., 

 ante, as M. hirundinacea of Australia, and M. ignipeclus of the 

 Himalaya ; 4, Pachyglossa, Hodg., ante, P. melanozantha ,• 5, Piprisoma 

 (XIII, 314), P. agilis ; and 6, Prionochilus, ante. The three first 

 differ chiefly in the degree of elongation of the bill,* and the two last 

 are also allied together ; and they combine to form a natural and satis- 

 factory group. 



Of the remarkable form noticed as Myzornis pyrrhoura in XII, 

 984, I find also the following description by Mr. Hodgson : 



Myzornis, H. " General structure of Yuhina (As. Res. XIX, 

 165), but slighter. Bill moderately slender, more or less cylindric, 

 and arcuate with both tips down ; the upper conspicuously longer, 

 and furnished with one sharp tooth : nares lineo- lunate, typically large 

 and soft % wings, tail, and feet as in Yuhina ; but the feet stronger, 

 and the wings and tail more feeble. Tongue brushed. Hab. North- 

 ern and central hills [oi Nepal.] 



" M. pyrrhoura, mini. Bright parrot-green, more or less merged 

 in rusty on the throat and vent. Outer margins of caudals, and of 

 mid-alars, fiery-red, or carmine : wings tipt with white. Lores black, 

 and black streaks on the crown. Legs fleshy : bill black. Length five 

 inches and a half ; bill eleven-sixteenths; tail one and five-eighths; 

 wing two and seven-sixteenths ; tarse fifteen-sixteenths ; central toe and 

 nail five-eighths ; hind nine-sixteenths. Remark. — These birds have the 

 manners and general structure of Yuhina : but they want the Bul- 

 boul-like crest common to all the species of that type : their more 

 slender bill is unidentate only, and their tarse is longer, being a third 

 plus the middle toe and nail ; it is also stout, and quite smooth. We 

 may here add, that our Sibia is another truly meliphagous form, pro- 

 per to these hills." 



Yuhina, Hodgson, since termed by him Polyodon, is re-defined as 

 follows, and a third species described ; the fiavicollis, passim, being 

 removed, and regarded as a distinct type, Ixulus. 



" Bill moderate, much depressed as far as the large nares, com- 

 pressed beyond. Tip of the upper mandible inclined, with three 

 [minute] teeth on each side: gape bristled, reaching to the eyes: 

 brows soft. Nares large, fossed, membranous ; the aperture lunated 



* This elongation of the bill is, I suspect, merely further carried out in Drepanis, 

 Tem., v. Melithreptus (in part), Vieillot.
