Family CERTHIID^. 



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 Certhiidce.
