DENDEOCOLAPTES. 



Dendrocolaptes, Hermann, Obs. Zool. p. 135 (1804) ; Scl. Cat. Birds Brit. Mus. xv. p. 169. 



Bendrocolaptes belongs strictly to the same subfamily, Dendrocolaptinae, as Ben- 

 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- 

 thomce, is found from British Honduras to the State of Panama and passes beyond into 

 Colombia. Another, B. puncticollis, occurs on higher ground in Guatemala and Costa 

 Eica. The third is the South-American B. validus, which penetrates our country as 

 far as Costa Eica, 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.
