Mr. Sclater admits sixteen species of Dendrornis aud gives the names of four others 

 which he was unable to determine. Mr. Elliot, going over the same ground, includes 

 twenty-two species in the genus. These are distributed over nearly the whole of 

 Tropical America, from the Mexican States of Tamaulipas and Sinaloa to Southern 

 Brazil. Five species are found within our limits, of which two occur in Southern 

 Mexico and Guatemala and the other three in the more southemi districts. D. eburnei- 

 rostn's is the only distinct endemic species, but the doubtful D. nana reaches the 

 extreme limits of our region and probably passes beyond them into South America. 

 Compared with that of Picolaptes, the bill of Dendrornis is stout and rather straighter, 

 the culmen curving rather more abruptly at the end. In other respects the two genera, 

 as well as Xiphocolaptes, are very similar, having plumage similarly marked, the wings, 

 tail, and feet are similarly constructed, and the nostrils in all are quite open.
