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. johanna has a short first primary and a moderately stout 
bill; it resembles P. ignicapillus and is probably a typical Prionochilus. 
P. olwvaceous has a short first primary and the bill somewhat stouter than 
P. johanne. Prionochilus quadricolor, P. bicolor, and P. inexpectatus 
resemble one another in having the bill short and very stout and the true 
first primary absent.
