206 List of a Collection of Birds 



but I do nol decide that they are distinct: yet if the different 

 colors are due to age, why should not some with orange colors 

 be among Buch a number of specimens from Yucatan ? 



Another marked difference, is the uniformly black middle 

 rec trices of the birds from Yucatan. 



( '. radiolatus from Jamaica is very distinct, a fine adult male, 

 has the front to the bill, the sides "t' the head and throat nearly 

 pure white; the upper plumage blacker, with the narrowtrans- 

 je white lines further apart than in ( '. aUnfrOM : the rump is 

 black, conspicuously barred with broad white lines ; the cen- 

 tral tail feathers are black, crossed with widely separated fine 

 white lines on the inner webs : the under plumage is dark 

 brownish-olive, middle of abdomen orange-red.

A single male specimen agrees closely with Swainson's de- 

 scription ; its validity, as a Bpecies, has been doubted by 

 many writers, and generally referred to ('. tricolor^ though 

 admitted to l»e distinct by Malherhe, and accurately figured 

 and described in his splendid Mon. of the PicidoB. It seems to 

 be very rare, as Malherbe states thai besides Swainson's ex- 

 ample, he only know.- of the male in his own collection. With 

 specimens before uie of ( '. tricolor from Bogota, St. Martha and 

 Panama, the distinctness of the two species does nol admit of 

 a Question. A- Btated by Malherhe, the bands on the upper 

 plumage of tricolor are t wice the width of those of rubrn en- 

 tris; in the 1 : i - 1 species the transverse white lines mi the back 

 arc similar t'» those of C. albifronSf while in tricolor they 

 are much as in ('. aurifrons y another marked difference is in 

 the central tail feathers; those of tricolor are deeply and 

 broadly indented with white on both webs, whereas in the ex 

 ample <>f rubriventris, these feathers are black, except for a 

 small space at the base on the outer web, where it is white, 

 color extending higher up nexl the shaft. In size and 

 . coloring the two Bpecies are much alike.
