Phylloscopus vieidipennis, nobis, n. s. A fourth species of the 

 Beguloides subgroup (J". A. S. XXIII, 487), and most nearly resembling 

 Ph. chloeonotus ; but readily distinguished from that species by having 

 the rump uniformly coloured with the back, also by having a longer and 

 differently coloured bill, and legs of much darker hue. From Ph. peore- 

 gultjs (Regulus modestus, Gould), it is distinguished by its inferior size 

 and much brighter colouring ; the mesial coronal streak being as much 

 developed as in Ph. chloronotus, and of a purer yellowish-white con- 

 trasting with a blacker shade of dusky : edge of wing considerably brighter 

 yellow than in the others; the wing-band and also the tibial plumes 

 tolerably bright yellow, the latter constituting another good distinction : 

 but a further and more conspicuous distinction consists in the wing be- 

 yond its coverts being uniformly green, without a trace of the Reg-ulus- 

 like variegation seen in Ph. peoeegulus, and less conspicuously in Ph. 

 chloeonotus : there is no dusky patch posterior to the coverts, nor 

 whitish tip or border to any of the great alars ; but the secondaries are 

 broadly margined with tolerably bright green, and the tertiaries are 

 merely of a duller green throughout, brightening on their outer edge, 

 and are not dusky and contrasting (as in the other species). In brief, 

 Ph. vieidipennis may be described to have the upper-parts vivid olive- 

 green, brightest on the margins of the wing and tail feathers : lower- 

 parts albescent tinged with yellow : crown dusky mixed with green, with 

 bright yellowish- white supercilia and coronal streak continued over the 

 occiput, the supercilia more yellowish anteriorly: a broad pale yellow 

 wing-band formed by the tips of the great coverts of the secondaries 

 and the smaller range of wing-coverts slightly tipped with yellowish 

 tibial plumes bright yellowish: the margin of the wing pure canary 

 yellow : upper mandible wanting in the specimen, but the lower is wholly 

 yellow. Legs infuscated-brownish. Length about 4 in., of which tail 

 If in. : wing 2 in. ; having the short first primary fk in., the second f in. 

 longer than the first, and f in. shorter than the longest primaries. Bill 

 to gape | in. ; and tarse f in. 



Hypsipetes Tickelli, nobis, n. s. Yery like H. Maclellandii, Hors- 

 field ; but devoid of rufous tinge on the breast and lower-parts, which 

 are uniformly coloured with the throat, and the throat-feathers are less 

 elongated and pointed than in the other : axillaries bright yellow ; and 

 much of the under surface of the wing pale sullied yellow : lower tail- 

 coverts dull yellow : upper-parts dull olive-green, slightly washed with 

 rufous on the back ; the wings and tail brightish golden-green, much less 

 rufescent than in H. Maclellandii: crown dingy rufous-brown, the
