 51; tail, 24; culmen from base, 13; bill from nostril, 9; tarsus, 15. 



This neutral-colored flowerpecker, which appears to be confined to the 

 mountains of Luzon, is difficult to describe, but it may be easily 

 recognized by its dull coloration.

Genus PRIONOCHILUS Strickland, 1841. 



Bill short and stout, very wide at base; gonys decidedly convex; first 

 primary less than one-half the second or wanting. The Philippine 

 species that are usually placed in this genus are not uniform in generic 

 characters. P. johannce has a short first primary and a moderately stout 

 bill; it resembles P. ignicapillus and is probably a typical Prionochilus. 

 P. olivaceous has a short first primary and the bill somewhat stouter than 

 P. Johannes. Prionochilus quadricolor, P. bicolor, and P. inexpectatus 

 resemble one another in having the bill short and very stout and the true 

 first primary absent.
