Two specimens of this apparently new species of Campylorhynchus 

 were procured by M. Boucard at Oaxaca in March 1858. They are 

 of different sexes, but present no outward distinctions. The bird is 

 most nearly allied to C. brunneicapillus of Northern Mexico, but 

 differs in its smaller size, shorter wings, and the shape of the spots 

 below, which are rounded instead of being elongated. The upper 

 surfaces of the two species are not dissimilar.

A specimen of this Thryothorus was obtained by M. Boucard at 

 Juquila in May last. It is something like T. rufalbus (Lafr.), but
