formal separation. Should this name he found not pertinent both the 

 Costa Rican and Colombian forms would have to stand as subspecies 

 of T. fraseri (Gould). 



One individual of this species was taken and two others seen in the 

 heavy forest of the coastal plain at Don Diego. They were feeding 

 as usual from the flowers of the wild plantain. They were noted dur- 

 ing the last days of the collecting at this point, and possibly further 

 search would have revealed more. This record involves a consider- 

 able extension of the range of the species.

Twenty-six specimens: Don Amo, Don Diego, Tierra Nueva, Tro- 

 jas de Cataca, Fundacion, and Dibulla. 



In this fine series the difference in the colors of the sexes, referred 

 to by Mr. Ridgway under typical hirsuta, is well illustrated. The 

 present form differs from hirsuta in its generally duller, paler colora- 

 tion, the abdomen and under tail-coverts being mostly grayish white, 

 with little or no rusty color except on the flanks. No. 44,552, Don 

 Diego, January 23, is a partial albino, the abdomen being almost 

 wholly white, as well as many feathers on the head. 



A Tropical Zone species, found throughout the lowlands, but very 

 scarce in the semi-arid portions. It is entirely a bird of the forest, 

 keeping low down. It is very partial to the blossoms of the wild plan- 

 tain, feeding from them exclusively in season. 



Mr. Smith sent in a nest with two eggs, collected at Don Diego on 

 May 19. " The nest, attached to the under surface of a wild banana 

 leaf, is composed of fine vegetable fibers and partly covered externally 

 with large strips of a greenish gray lichen. The eggs measure 15X9 

 mm., being very elongate oval, the two ends similar in form."
