Eab. Costa Eica, San Jose [Hoffmann), San Jose (Carmiol^, v.Frantzius^); Pakama, 

 Volean de Chiriqui, Bugaba {Arc6 ^). 



Little has been recorded of this species. It was described by Dr. Cabanis from 

 specimens obtained near San Jose, Costa Eica, by Dr. Hoffmann ; but the adult male 

 was not represented in this collection. It has since been secured by Arce in the 

 Volean de Chiriqui, and one of his specimens is now figured. 



In general colbratidn E. gracilis is like E. affinis : but it may be at once distinguished 

 by its wholly black tail, and by the steel-blue black throat-mark being more extensive 

 and reaching quite to the breast. E. luteicapilla has also a black tail, but the 

 yellow of the crown is more extensive, reaching to the nape. E. minuta, again, is 

 characterized by its white crissum. 



5. Euphonia luteicapilla. (Tab. XVI. fig. 1.)

Mtens cseruleo-nigra ; alis et cauda viride seneo nitentibus hao immaoulata, fronte angustissime et loris nigris,

 chondriis olivacea indutis. (Descr. feminse ex Chepo, Panama. Mus. nostr.) 



Hab. Costa Eica {v. Frantzius ^), San Jose (v. Frantzius ^), Turrialba (Carmiol) ; 

 Panama, Volean de Chiriqui, Bugaba \ Boquete de Chitra *, Cordillera del Chucu 

 (Arce), Paraiso Station, Panama Eailway (Hughes ^), Chepo (Arce). 



We possess a good series of specimens of a Euphonia from the State of Panama, 

 which we believe to be this species, but from Costa Eica we have only a single female 

 or young male example. None of the adult males from Panama have a white spot on 

 the inner web of the outer rectrix, and in this respect differ from Dr. Cabanis's descrip- 

 tion ; but as he says that this spot is small and sometimes absent, its importance is not 

 great. 



The yellow crown at once distinguishes this species from all its allies ; this not only 

 occupies the anterior portion of the crown, but spreads backwards to the nape. 



We have figured one of the Panama specimens from Bugaba ; and here as well as 

 in the rest of the State as far south as Chepo E. luteicapilla appears to be spread.
