A series of specimens from Jamaica differs from Cubaij in being 

 rather smaller in size, and in having the chestnut brown of the under 

 parts considerably deeper and more marked, extending along the

 bird from Jamaica d-iffers from the adult in lacking the frontal band 

 almost entirely, and in having a whitish chin. I have not had an 

 opportunity of examining the St. Pomingau species, but would not 

 be surprised if it proved different from those of Cuba and Jamaica. 



A closely allied species is the P. i^uficollaris, of Peale.*
