There has long been considerable doubt whether the bird described by Lesson from 
Realejo as Picolaptes capistrata 4 is distinct from one from Mexico, called by Lafresnaye 
Campylorhynchus rufinucha—the latter having the. back conspicuously striped and the 
flanks sparsely spotted with black, the former having the back plain chestnut and the 
flanks without marks. Des Murs2, when figuring the type of C. capistratus, considered 
C. rufinucha to have been applied to a younger individual of the former; and this 
view was generally accepted until Prof. Baird wrote his ‘Review of American Birds’ 
and reinstated C. rufinucha as a species 4. We were at one time } disposed to follow 
Prof. Baird in thus recognizing two species ; but now, by the light of additional speci- 
mens, we doubt the existence of more than one; for the extent of the markings of 
the back is found to be variable, and not correlated with the spotting of the flanks. 
Nor can we fix the birds with spotted backs to any special locality. Prof. Baird sup- 
posed C. rufinucha to be the species of Eastern Mexico; but we trace it in some of its 
characters to Costa Rica, specimens of the true C. capistratus being found at immediate 
points. 
C. capistratus has a wide range in Central America, being found from the State of 
Vera Cruz in Mexico to Costa Rica. It nowhere occurs at a higher elevation than
