nuatum : culmine basi carinato, versus apicem leviter arcuato. 

 Mandibula tomiis rectissimis. Nares basales, magna?, superne 

 membrana clausae, inferne rima longitudinali apertae. A Ice : re- 

 miges, 1 spuria, 2 et 3 abrupte longiores, 4 — 8 longiores sub- 

 a?quales externe emarginatae, ceterae gradatim breviores cu- 

 neatae. Fedes subelongati. Digitus exterior a medio ad basin 

 connexus : hallux validus. Ungues compressi arcuati acuti,

The straightness and slenderness of the bill distinguish Ortho- 

 tomus from the two former genera ; these characters, with the 

 depression and triangular form of the base of the bill, prevent 

 its union with the other genera of this family. I have not been 

 able to determine satisfactorily the affinity of this genus. The 

 slenderness of the bill and its other habits associate it with the 

 Certhiadce ; in the acumen of the bill and the size of the hallux 

 it resembles in some degree the genus Sitta.

The general description of the Certhia olivacea, Linn. Syst. i. 

 p. 185. 5, a native of Madagascar, applies to this bird ; but our 

 species exceeds the former three inches in length, and it wants the 

 white orbits.
