564 Notices and Descriptions of various new [No. 164. 



brightish olive-green : under-parts ashy, more or less pure, and pass- 

 ing to rufescent- whitish on the belly ; the lower tail-coverts bright 

 yellow ; and the throat whitish, slightly tinged with yellow in one of 

 two specimens : bill dusky, the basal two-thirds of the lower mandible 

 yellowish ; and the legs pale. 



The true Z. madagascariensis also inhabits the Mauritius : but this, 

 as Mr. Strickland informs me, is a short-beaked species, and therefore 

 cannot be the same as the foregoing; besides that the description 

 of it does not sufficiently apply to Z. curvirostris. 



Z. (?) borbonicus, (Brisson). This is nearly allied to Zoster ops, 

 but is without the white orbital feathers so characteristic of that 

 genus ; it has also much the look of the British Curruca sylviella (upon 

 a superficial view), but has no particular affinity for the latter.* It is 

 probable that some more immediate congeners of this bird inhabit 

 Australia, where not only the genus Zosterops attains its chief deve- 

 lopment of species, but also more especially the great austral group 

 Meliphagidce, to which Zosterops strictly belongs. The present spe- 

 cies is also from the Isle of France. 



Genus Phyllornis, Boie, v. (subsequently) Chloropsis, Jardine and 

 Selby. The gradual enrichment of the Society's museum enables me 

 now to offer a more satisfactory synopsis of this genus than that at- 

 tempted in XII, 955 et seq. 



A. With thicker bills, the upper mandible abruptly bent over (more 

 or less so, indifferent specimens,) and sometimes quite hooked at tip. 

 The shoulder of the wing uniformly green with the rest. Peculiar to 

 the Malay countries. 



1. Ph. Sonneratii, (Jardine and Selby): Ph Mullerii, Tem. ; female, 

 Turdus viridis et Chloropsis zosterops of Horsfield : young male, Chi. 



gampsorhynchus, Jardine and Selby. 



2. Ph. cyanopogon, Tem. : female, (or perhaps young male,) Chlo- 



* By the way, I may here notice that the Curruca sylviella (v. garrula), so 

 called, of S. India, is conspicuously a larger bird than its European relative, having 

 the wing fully two inches and three-quarters long, and the rest in proportion : the 

 general tone of colour is also somewhat darker, and the bill and legs are proportionally 

 larger and stronger, the tarse measuring from thirteen-sixteenths to seven-eighths of 

 an inch. As for the roseate tinge on the under-parts mentioned by Sykes, this is 

 common to fine specimens from either country. I certainly consider the Indian bird 

 to be distinct, and shall therefore name it C. affinis. 



Prof. Behn also informs me, that the species assigned to C. orphea by Mr. Jerdon, 

 is not the true C. orphea of continental Europe.
