This is the commonest and most widely spread species of Dendrornis found in our 
country, its range extending from the Mexican State of Tamaulipas in the north-east 
and that of Sinaloa in the north-west, southwards to Guatemala, Honduras, and Nicar- 
agua. Mr. Elliot, in his recent monograph of the genus, also includes Costa Rica in 
its range, but omits to give his authority for so doing )° | 
Its range in altitude reaches from the sea-level to a height of about 4000 feet in the 
mountains. It lives in the forests, climbing trees like a Woodpecker, and feeding on 
insects. 
The bird of Western Mexico was separated under the name D. mentalis by Mr. Law- 
rence, and has long been considered distinguishable from the eastern and southern 
D. eburneirostris ; but Mr, Elliot, after examining a large number of specimens, came 
to the conclusion that the distinctness of the two could not be upheld. - We are now 
entirely of the same opinion, and, with an extensive series before us from all parts of 
the range of the species, no separation appears to us possible. 
_ Birds from Western Mexico are, as a rule, paler than the average in the general 
tone of their plumage, but they can be exactly matched by examples from Tamaulipas 
and Yucatan, and these are connected with the darker birds of Vera Cruz and other 
places by gradual steps, the extreme forms often occurring, as on the Isthmus of Tehu- 
antepec, in the same district at the same time of year. Great variation also occurs in 
size and in the dimensions of the bill, but also without reference to locality. 
Swainson’s name for this species was based upon a bird sent by Bullock from
