520 NOVELTIES. 



secondaries pale pure pearl grey ; primary greater coverts 

 orey, tinged more or less with dusky ; primaries dark brown, 

 margined albescent and the later ones especially much suffused, 

 towards their bases with grey ; the lateral tail feathers next the 

 central pair a delicate French grey on their upper surfaces, 

 paling to white towards the tips, and faintly tinged brown on 

 part of the outer webs ; on the lower surface the terminal 3 

 inches greyish white, below this blackish dusky, paling again 

 towards their bases ; the external tail feathers of all with the 

 terminal 2*4 inches, and the whole outer web, except a slatey 

 grey (on the upper surface) or dusky patch towards the middle 

 of this latter, white : basal portion of the inner webs brownish, 

 slatey on upper, and black on lower surface, paling, slightly 

 only, towards the extreme bases. The intermediate feathers are, 

 intermediate in character between these two pairs. 



Cettia Stoliczkae, Sp. Nov. 



Precisely like C- sericea, but altogether paler and much less rufescent; 

 the bill slightly slenderer ; the legs and feet fleshy white. Sexes differ 

 conspicuously in size. 



Although in almost every respect so very similar to Cetti's 

 Warbler as to need no separate detailed description, Stoliczka's 

 Warbler yet differs so markedly in the particulars above indi- 

 cated that I do not hesitate to characterize it as distinct. 



The upper surface is colored more like //. olivetorum than 

 C. sericea. A dull grey brown tinged on the back with rufous, 

 which is only conspicuous on the rump and upper tail-coverts. 

 The following are the particulars recorded in regard to a male 

 by Dr. Stoliczka : — 



" Length, 6'3; wing, 2-75 ; tail, 2*8; tarsus 0*9; expanse, 

 8*15; bill, at front, 0'44 ; bill, from gape, - 68. The irides 

 brown, and upper mandible horny brown, lower fleshy brown; 

 legs and feet whitish fleshy." 



The female is much smaller; length, 5'6 ; wing,»2'35; tail 

 2*4 ; tarsus, 0*8. 



Only a pair were preserved, — these I have compared with a 

 large series of sericea, none of which at all approach these 

 Yarkand birds in tint, none have quite such slender bills, and 

 in none is there such a marked difference in the size of the 

 sexes observable.
