Dendrocincla homochroa was one of M. Boucard’s discoveries}, the first specimen 
having been obtained by that traveller at Teotalcingo, a village on the eastern slope of 
the mountains of the Mexican State of Oaxaca. As its name is not included by 
Sumichrast in his list of the birds of Vera Cruz, and as none of our collectors who 
have worked in that State have sent us specimens, we conclude that the bird is not 
found to the northward of Teotalcingo. Southward of this place and over the whole 
of the forest-region of Yucatan and Guatemala, on both sides of the Cordillera, it is to 
met with pretty frequently. It occurs also in various parts of Nicaragua, on both 
sides of the great lakes, and in Costa Rica and the adjoining district of Chiriqui. 
Whether the bird found at Panama is really distinct must remain for the present in 
some doubt. No specimen of the large series of the more northern bird quite corre- 
sponds with the type of D. ruficeps; some equal it in size, and some have the head of 
the same rufous tint, but none have so large a bill, and all are rather more rufescent 
both above and below. 
D. homochroa is not unfrequently found in company with D. anabatina in some 
numbers together picking ants from the trunks of the forest-trees. ‘They are less 
active than the other members of the climbing Dendrocolaptide. |

Mr. Ridgway includes all the birds found between Nicaragua and the line of the 
Panama railway under the name Dendrocincla homochroa ruficeps; but our series hardly 
confirms this view, for amongst the specimens from Chinandega and its neighbourhood 
are some not to be distinguished from the Mexican type, whilst others are darker. 
Moreover, there is a considerable difference in size, the males being apparently a little
