DENDROCOLAPTES. 
Dendrocolaptes, Hermann, Obs. Zool. p. 185 (1804) ; Scl. Cat. Birds Brit. Mus. xv. p. 169. 
Dendrocolaptes belongs strictly to the same subfamily, Dendrocolaptine, as Den- 
drornis and its allies, as it has the same structure of wings, tail, and feet, as well as the 
open oval nostrils of those birds. Its difference lies in the form of the bill, which is 
much wider at the base and not compressed; the culmen curves slightly towards the 
tip, where it bends rather abruptly to form a distinct hook to the maxilla, and there is 
a slight notch near the end of the tomia. 
Some difference of opinion prevails as to the number of species contained in Dendro- 
colaptes, Mr. Sclater admitting nine, D. intermedius of Count Berlepsch being unknown 
to him. Of these, three occur within our borders, the commonest of which, D. sancti- 
thome, is found from British Honduras to the State of Panama and passes beyond into 
Colombia. Another, D. puncticollis, occurs on higher ground in Guatemala and Costa 
Rica. The third is the South-American D. validus, which penetrates our country as 
far as Costa Rica, and has an extensive range in the northern portion of the Southern 
continent.

more rufous wings, narrower shaft-stripes on the head, neck, and under surface, and by 
its larger paler bill.
