Ornithion imberbe ? 



I brought a specimen with me that probably pei tained to this species; 

 but imfortunateiy while at the American Museum in New York it was 

 carried away by a rat before 1 had opportunity to identify it. 



Tyranniscus parvus. 



Costa Kican specimens are intermediate in size between true jturcus 

 and rillissiinus; rliey are also more yellowish below than j^arvus from 

 Panama. However, the relationship throughout seems the closer to 

 parvus. 



Empidouax albigularis. 



1 have a specimen that certainly does not agree very closely with 

 Mr. Sclater's description (Cat. Birds Brit. Mus., xiv, p. 223) ; however, 

 compared with examples in the Smithsonian collection that dift'er in 

 the same way, but which have been ideutilied as E. albif/tilaris by Mr. 

 Sclater, it is fonnd that they agree. 



Coutopus lugubris. 



A female in freshly assumes plumage, is much richer colored than 

 any of the three examples, including the type, in the Smithsonian col- 

 lection. Above and below it is much more of an olive. In size it is 

 also a tririe smaller. The specimens in the Smithsonian collection are 

 all in much worn plumage. 



Platypsaris aglaiae (Lafr. ).' 



A single female, taken at Jimenez, in tierra caliente, on the Atlantic 

 side of Costa Rica. 



Pachyrhamphus versicolor. 



A hue male, taken at La Palma de San Jose, Costa Rica. 



Pipra velutina Berl. 



Male Costa Rican specimen from Pozo Azul agree closely with 

 Panama exami)les, but have a greenish shading on the rump and upper 

 tail-coverts, and also below on the center of the belly, and decidedly 

 developed on the under tail-coverts. This may, however, be a character 

 of the young. 



A female is parrot-green above, slightly brighter on the head and 

 duller on the rumj). There are three or four blue feathers in the crown. 

 Below the breast is duller green, the throat greenish gray ; the sides 

 are paler, while the center of the belly and the crissum are greenish 

 yellow.
