COTINGID.E. 



Tityra semifasciata costaricensis Ridgway. Nine adults, both sexes, 

 Boruca, and Barranca Puntarenas, April, May, June and August. 



Tityra albitorques fraserii (Kaup). Five specimens, adult male and 

 female and three young, Paso Real, July 20-22. The young are in nestling 

 plumage and have the back and wings much suffused with yellowish brown, 

 the whole side and top of the head reddish brown, spotted with blackish 

 on the occiput. 



Pachyrhamphus cinereiventris Scl. Six adults, both sexes, Boruca, 

 Barranca Puntarenas, Paso Real and Pozo del Rio Grande, May, July and 

 August. 



Lathria unirufa clara Ridgw. Two adults, male and female, Pozo del 

 Rio Grande, April 5 and 17. 



Attila citreopygia citreopygia (Bonap.). Four adults, both sexes, Boruca 

 and Pozo del Rio Grande, April and May. 



Attila citreopygia luteola Ridgw. One adult male, Pozo del Rio Grande, 

 April 15. 



Mr. Ridgway kindly identified these five skins of Attila and decided 

 that four of them were referable to true citreopygia and one to luteola, 

 from which it seems reasonable to infer that the Rio Grande region of 

 Costa Rica is the meeting ground of these two races. 



Microtriccus semiflavus semifiavus (Scl. & Salv.). 1 One adult male, 

 Boruca, May 4, 1906. 



Chasmorhynchus tricarunculatus ./. & E. Vcrr. One female, Pozo del 

 Rio Grande, April.
