 of quills nearly white. Bill slender, Phylloscopine, dark brown, with 

 the under mandible paler at the base. Legs, feet, and claws brown. 

 Fourth primary slightly the longest ; second primary generally in- 

 termediate in length between the eighth and ninth, in very rare 

 instances between the seventh and eighth, or between the ninth 

 and tenth ; the exposed part of the bastard primary measures 0-5 

 to 0-6 inch. Length of wing 2-35 to 2-U4 inches, tail 1-9 to 1-65, 

 culmen 0"4 to 0'45. 



Winter plumage. Similar to the autumn plumage, but with the 

 mesial line on the crown, the bar across the wings, and the pale 

 tips to the quills more or less abraded. 



Brooks's Barred AMllow-Warbler breeds in the highlands of North- 

 western Cashmere in abundance, and winters in the plains of the 

 North-west Provinces of India, as far east as Cawnpore.

The genus HypoJais is a small group of birds chiefly remarkable 

 for laying eggs luiving a french-grey or salmon-coloured ground. 

 They form the connecting link between Phylloscopus and Acroce- 

 phalus, havitjg the nearly even tail of the former and the large bill 

 of the latter. From the large-billed subgencric group of the ibrmcr 

 (Acant/iopneustts), besides the diflerence of the coloration of the eggs, 

 already alluded to, tliey can only be distinguished by the absence of 

 the pale tips to the wing-coverts, which in AcantJwpneustes form one, 

 and often two pale bars across the wings. 



All the species of this genus appear to be more or less migratory. 



* This writer, a swell as others, spells the word erroneously Hippolais, under 

 a mistakeu idea of its derivation.
