the District of Lampong, S.E. Sumatra. 311 
the former is more nearly allied to C. lugubris, if the Bornean 
specimen marked C. hasselti in the British Museum is cor¬ 
rectly determined. 
Corydalla lugubris , Walden, differs from C. malayensis in 
having white superciliary patches before the eye, in the breast- 
markings consisting of a few sparse narrow brown lines, and 
not broad brown centres to the feathers, and in the ground¬ 
colour of the breast being albescent, and not pale rufous. 
Above, the colouring and markings of the two species are 
very similar.

Prinia familiaris, Horsf. t. c. p. 165, “ Java " (1820); Zool. 
Res. Java, t. 52. 
Motacilla olivacea, Raffles, t. c. p. 313, “ Sumatra” (1821). 
Mr. Buxton's Sumatran examples are identical with typical 
specimens. One of the Sumatran birds possesses white lores. 
The species also occurs in the island of Madura. 
99. Prinia rafflesi, sp. nov. (Plate VI. fig. 1.) 
Mr. Buxton's collection contains two examples of a species 
of Prinia I am unable to identify. It may be the same as M . 
olivacea, Raffles (/. c.); but that bird has been determined 
by Horsfield and Moore (Mus. E.I. C. i. p. 320) to be P. 
familiaris . 
Above olive-green, front of head ashy. Lores, which ex¬ 
tend partly over the eye, white. Chin, throat, cheeks, and 
upper breast white. Lower breast, abdomen, flanks, ventral 
region, and under tail-coverts pure canary-yellow. Thigh- 
coverts yellow, tinged with ferruginous. Carpal edge and 
under carpal coverts yellow-white. Quills brown, with olive- 
green edgings. Rectrices pale brown, washed with green, 
and with an obscure darker brown subterminal spot and pale 
tips. Bill black and slender as compared with that of P. 
familiaris. Bill from forehead 0-72, wing 118, tarsus 0-75, 
tail 2*50. 
Differs from P. familiaris in wanting the conspicuous white 
tips to the minor and major wing-coverts, in being darker 
olive-green above, in the olive-green fringings of the quills
