Bill gently curved, moderate in length, slender, decidedly compressed 
beyond nostril, and with an obsolete notch in cutting edge near tip; cul- 
men with a distinct ridge; nostril-opening linear, exposed, and overhung 
by an operculum; rictal bristles few and very short; no frontal bristles; 
a number of long retrorse hairs springing from among the feathers of 
forehead; wing moderate in length, flat, and somewhat pointed; first 
primary slender and less than one-third of second, the latter nearly 
equal to third, fourth, and fifth which are subequal and longest; tail 
square, little more than one-half of wing; divisions between tarsal scutes 
obsolete; tarsus, longer than bill from nostril, and equal to, or shorter 
than, middle toe with claw. The characters detailed above are taken from 
Rhabdornis, a genus not typical of the family, but the only Philippine 
representative of the Certhide.
