260 TANAGRIDA. 
Nitens ceruleo-nigra fere unicolor ; pileo antico usque ad oculorum medium et abdomine toto luteis ; alis subtus 
albis; cauda omnino nigra; rostro et pedibus obscure plumbeis. Long. tota 4:0, ale 2-3, caudex 1:3, 
rostri a rictu 0°45, tarsi 0-6. (Deser. maris ex Volcan de Chiriqui. Mus. nostr.) 
@ supra olivacea, subtus multo pallidior, ventre medio flavicante. (Descr. femine ex Costa Rica. Mus. P. L. 
Sclater.) 
Hab. Costa Rica, San José (Hoffmann), San José (Carmiol *, v. Frantzius*); Panama, 
Volcan de Chiriqui, Bugaba (Arcé®>). 
Little has been recorded of this species. It was described by Dr. Cabanis from 
specimens obtained near San José, Costa Rica, by Dr. Hoffmann; but the adult male 
was not represented in this collection. It has since been secured by Arcé in the 
Volcan de Chiriqui, and one of his specimens is now figured. 
In general coloration 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. . luteicapilla has also a black tail, but the 
yellow of the crown is more extensive, reaching to the nape. LE. minuta, again, is 
characterized by its white crissum.

Nitens ceruleo-nigra ; alis et cauda viride neo nitentibus hac immaculata, fronte angustissime et loris nigris, 
capitis lateribus et gula dorso concoloribus, subalaribus albis; pileo toto et abdomine luteis ; rostri maxilla 
cornea ad basin et mandibula (preter apicem) pallidis; pedibus obscure corylinis. Long. tota 3°5, alee 
2°15, caude 1:3, rostri a rictu 0°3, tarsi 0-5. (Descr. maris ex Bugaba, Panama. Mus. nostr.) 
Q supra olivacea, alis caudaque fusco-nigris extus olivaceo limbatis; subtus flavida, medialiter clarior, hypo-— 
chondriis olivacea indutis. (Descr. femine ex Chepo, Panama. Mus. nostr.) 
Hab. Costa Rica (v. Lrantzius'), San José (v. Frantzius*), Turrialba (Carmiol) ; 
Panama, Volcan de Chiriqui, Bugaba+, Boquete de Chitra’, Cordillera del Chucu 
(Arcé), Paraiso Station, Panama Railway (Hughes 4), Chepo (Arcé). 
We possess a good series of specimens of a Huphonia from the State of Panama, 
which we believe to be this species, but from Costa Rica 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 . luteicapilla appears to be spread.
