located. But the whole vast series of Insessores stands exceedingly 

 in need of thorough revision by a naturalist of sufficient penetration 

 to distinguish between mere superficial modifications bearing reference 

 to habit, and the more immediate subtypes of form upon which such 

 varied modifications are especially based. 



23. Heterornis (olim Cutia) Nipalensis, Hodgson, Journ. As. Soc. 

 1836, 771- A singular form, not without some distant affinity to the 

 last, but nearly related to nought with which I am acquainted. 



24. Pteruthius erythropterus, Swainson ; Lanius erythropterus, Vigors, 

 Proc. Zool. Soc. 1831, 22, and figured in Gould's Century, PI. XI. 

 Female, differing from the figure in Gould's work by having the back 

 and scapularies more tinged with cinereous, and the purer ash-grey 

 of the head continued to beyond the occiput, and including the 

 ear-coverts. A young male differs in the looser texture of its clothing 

 feathers, in having the head and ear-coverts concolorous with the 

 back, and the same defined white streak commencing above the eye as 

 in the mature male ; this being wanting, or only the merest trace exist- 

 ing of it, in the female. 



25. Pt. rufiventer, Nobis, n. s. ? Female allied to the preceding 

 species, but differing in the disposition of its colours, in having a longer 

 and more graduated tail, and in its beak being somewhat longer and 

 more compressed, with the terminal hook of the upper mandible rather 

 less developed. Length 7f inches, of wing from bend barely 3^ inches, 

 and middle tail feathers 3f inches, the outermost 1^ inch shorter ; bill 

 f inch to forehead, and 1 inch to gape; tarse 1^ inch. Back and 

 scapularies vivid olive-green, a little mingled with black, which may be 

 the predominant colour of these parts in the male : forehead, lores, 

 super-orbitary region, sides of the head, ear-coverts, throat, and breast, 

 ash-grey, passing into deep black on the crown, which colour is con- 

 tinued over the occiput and nape : rest of the under-parts dull ferrugi- 

 nous, with an ill-defined broad zone of saffron across the lower part of 

 the breast, bordering the grey : upper tail-coverts, and tips of the secon- 

 daries and of the longest tertiary, together with those of all the tail- 

 feathers, deep ferruginous : wings principally green externally, the 

 winglet and primary-coverts black, and all but the two outermost 

 primaries more or less edged with whitish-grey, towards the tip only in 

 the more inward, the rest of the edging being green : internally all the
