Phoenicothraupis salvini peninsularis. Yucatan Tanager.

 tan, 1880; Geo. F, Gaumer.

Similar to Phcenicothraupis salvini salvini, but adult male much 

 darker and less brightly colored, the back, etc., dull reddish brown, the 

 under parts of body strongly tinged with grayish. (Nearly intermedi- 

 ate in coloration between P. salvini salvini and P. fuscicauda, but

Type, no. 126942, U. S. National Museum, $ ad., Rio Escondido, 

 eastern Nicaragua, May 12, 1892; Chas. W. Richmond. 



Chlorospingus sumichrasti. Sumichrast's Chlorospingus.

Mountains of Vera Cruz, southeastern Mexico.

Genus Iridophanes. (Type, Dacnis pulcherrima Sclater.) 

 Similar to Tatiagrella, Swainson, but nasal fossae mostly unfeath- 

 ered, bill more slender (though relatively broader basally), and four 

 outermost primaries (sixth to ninth) more nearly equal in length. 



Although this form has usually been considered a member of a 

 Coerebine genus {Dacnis) I am inclined to believe that its relationships 

 are in reality Tanagrine, as has already been suggested by DuBus, ac- 

 cording to Dr. Sclater.^
