Obs.—It is, perhaps, probable that in Yucatan this race grades into the M. stolidus (var. stolidus), since there is a specimen in the collection from Merida (39,213, April 9, 1865, A. Schott) which seems to be very nearly intermediate in every way between the two. It has the very black hill, restricted rufous on inner webs of rectrices, and pale yellow of lower parts of M. stolidus, and the brown pileum and more robust proportions of irritabilis. The specimen, however, is in poor condition, being of worn and faded plumage, and much distorted, so that its true characters cannot be ascertained satisfactorily.

Obs.—The most typical specimens are from Mazatlan and northward, across the northern portion of Mexico. On the eastern coast, specimens from Mirador and Orizaba already strongly incline toward var. nigricapillus.
