 Brit. Mus. VI, p. 195, I find that he describes the Costa Rican 

 form of this species. Tlie dimensions noted by him and taken 

 from an adult male collected at Parita, Costa Rica, 5th April, 

 1807, by J. Carmiol, are just tiie same as those of my Costa

 former has the feathers of the top of the head tipped with a purer 

 ail J clearer ash (not so brownish as in zo?tat/is). The light bands 

 on the quills are narrower and wdiiter. The light and black 

 bands on tlie middle tail-feathers are also more regular on the
