370 Canon Tristram on an apparently 



to a distinct species. But the Professor sent to me a specimen 

 which he has had several years in spirit^ and which Mr. Cul- 

 lingford, of Durham, has now very carefully prepared. This 

 bird is very near mine, but the grey on the back seems 

 slightly tinged with green, and the yellow wash on the throat 

 is more decided, while the tarsus is slightly shorter. Of 

 course, however, it is dangerous to draw any positive con- 

 clusion as to coloration from a specimen which has been 

 eight years in spirit. My bird has every appearance of 

 being fully adult, and has not been in spirit. I therefore 

 venture to describe it as new, and to call it

I take this opportunity, with the kind assent of the Editors 

 of 'The Ibis,^ of adding a figure (Plate XI. fig. 2) of my 

 Zosterops hnvarum, recently described in this Journal (Ibis, 

 1887, p. 234) . 



The following is a short synopsis of the species oi Zosterops, 

 so far as at present known, from Madagascar and the 

 Mascarene Islands :— 



Green-backed Species. 



Z. semiflava, E. Newton. Uniform greenish yellow above, 

 brighter on the rump; lower parts rich yellow, with 

 chestnut flanks. — Hab. Seychelles. 



Z. mayottensis, Schlegel. Not seen by me ; it seems from 

 the description and from Pollen and Van Dam^s figure 

 to be very close to Z. semiflava, but with a bright citron- 

 yellow forehead. — Hab. Ins. Mayotte. 



Z. kirki, Shelley. Uniform greenish yellow above ; uni- 

 form lemon-yellow below. This species has recently been 

 described by M. Oustalet. — Hab. Grand Comoro Island. 



Z. anjuanensis, E. Newton. Greenish yellow above, with 

 narrow orange forehead and black lores; chin, throat,
