M. Simon says of this form that it is absolutely the same as S. 

 ftammula with the single exception of the color of the throat, and 

 should be considered only a subspecies of that form. " S. torridus 

 Salv. ne differe absolument de S. ftammula que par la teinte de la 

 gorge et il serait mieux de le considerer comme subspecies." 



I have never seen any males from the Volcan de Chiriqui, only 

 females in Mr. Bangs' collection, but it seems quite probable that all 

 of the birds there might be of this form. The fact that specimens of 

 the variety S. f. torridus have been taken on Irazu in company with 

 true S. ftammula is rather hard to explain, providing one recognizes 

 S. torridus as a subspecies of 6". ftammula. It is possible that the 

 birds from Irazu are faded or stained specimens of ftammula , while 

 those occurring farther south are true torridus. The young male from 

 the Dota mountains is undoubtably true torridus, for the lilac feathers 

 are just coming out and are the proper color for torridus. A good 

 series of males from the Volcan de Chiriqui would clear up this ques- 

 tion quite thoroughly. 



The bird is found only at high altitudes, usually at or above timber- 

 line.
