far as external characters go, seems to be the most nearly 

 allied form to Rhabdornis , the tongue has the extremity entire, 

 and the upper surface as well as the sides beset with short 

 bristles, giving it a remarkably brush-like appearance. 



I am not at present prepared to express an opinion as to 

 the importance of the shape of the tongue as a character in 

 classification, though I believe from what I have already 

 seen that some useful hints may be derived from this source, 

 which may lead to a better arrangement of the Passeres. I 

 intend on a future occasion to publish the results of my 

 investigations on this subject.

This new species is most closely allied to Z. jiava (Horsf.), 

 which is found in Sumatra, Java, and Borneo, and to Z. ni- 

 groi'um, Tweed., from Negros. It is easily distinguished 

 from the former by the almost uniform olive-green upper 

 parts, only the forehead, rump, and upper tail-coverts being 

 slightly brighter and washed with yellow; and from the latter 

 it differs in having no black spot in front of the eye, the 

 upper parts brighter olive, and the yellow on the throat 

 and middle of the uuderparts more golden with no greenish 

 tinge.
