130 DR. P. L. SCLATER ON NEW AMERICAN BIRDS. [Mar. 26, 



bus pallide f avis ; crisso fulvescenti Jlavo : rostro nigra, man- 

 dibulo inferiore phimlescente ; pedibus carneis. 



Long, tota 675, alse 3-2, caudse 2-9. 



Hab. In Venezuela et ins. S. Trinitatis. 



This Tanager is a climatic form of Tanagra cyanocephala of Trans- 

 andean Peru and Ecuador, and T. auricrissa of New Granada. It 

 most closely resembles the former bird, but may be distinguished by 

 the paler ashy colour of the lower surface, the duller yellowish-green 

 of the crissum, and the less extent of the yellow on the under parts 

 of the wings. The wings are also comparatively shorter, and there 

 is less olivaceous colouring on the flanks of the Venezuelan bird. In 

 the New Granadian T. auricrissa the under surface is tinged with 

 blue, and the crissum is golden yellow. 



9. RaMPHOCELUS EPHIPPIALIS. 



cJ . Coccineus : alis et cauda cum tibiis et subalaribus nigris : 

 interscapulii totius plumis nigris obscuriore coccineo tertninatis: 

 rostro et pedibus nigris, illius mandibula inferiore ad basin 

 alba. 



5 . Similis R. brasilii et R. dorsalis /cewiwiw. 



Long, tota 7'5, alee 3-1, caudse 3-1. 



Hab. Inripis fl. Amazonum sup. 



This Jtamphocelus, of which I have specimens of both sexes, re- 

 ceived by M. Verreaux from the Upper Amazon, is only distinguished 

 from B. brasilius by its back between the wings being black, with the 

 margins of the feathers only scarlet. In this respect it is further 

 removed from R. brasilius than R. dorsalis, which is exactly inter- 

 mediate between the two. M. Jules Verreaux informs me that all 

 the specimens received from this locaUty were similarly marked ; so 

 that the variation, though small, seems to be constant. 



10. Saltator isthmicus. 



Olivaceus, uropygio grisescente ; alis fusco-nigris, extus olivaceo 

 limbatis : cauda fusco-grisescente, rectricum apidbus albican- 

 tibus : subtus sordide albus olivaceo Jlammulatus, gula imma- 

 culata et cum ventro hno et crisso albicantibus : tectricibus sub- 

 alaribus fulvescenti-alUs, campterio flavido : rostro nigro, 

 pedibus corylinis. 

 Long, tota 7"0, alse 3'5, caudse 3*6. 

 Hab. In Isthmo Panama. 



I have two specimens of this Saltator in my collection. I obtained 

 them from Mr. John Bell, of New York, in 18.56, who informed me 

 that he shot them on his passage across the Isthmus of Panama on his 

 return from California. The species is very closely allied to two 

 others in my collection — one from Trinidad, which I take to be the 

 Saltator maculipecius ; and the other from Bogota, which I consider 

 to be probably S'. striatipectus of Lafresnaye. The three species, 

 however, are so closely allied, that it is possible that one of M. de 

 Lafresnaye's descriptions may be intended for the present bird.
