108 PIPRIDZ. 
Supra olivaceo-viridis, alis et cauda nigricantibus, dorsi colore limbatis, illarum secundariis intimis in pogonio 
interno lactescenti-albidis; capite toto griseo, oculorum ambitu albo: subtus viridi-flavus, pectore et 
hypochondriis olivaceis, subalaribus flavido-albidis, tectricibus elongatis, margine alarum juxta nigris 
remigibus interne ochraceo-albidis: rostro et pedibus plumbeis. Long. tota 4°5, ale 2-5, caude 1°8, rostri 
a rictu 0:5, tarsi 0°5. (Deser. exemp. typ. ex Tucurriqui, Costa Rica. Mus. nostr.) 
Hab. Costa Rica, Tucurriqui (Arcé !*), 
A single specimen sent us by our collector Enrique Arcé from Costa Rica in 1864 is 
the only one that has as yet come under our notice. It belongs to a little group of four 
species which are distributed over the chief mountain masses of South America; thus 
Eastern Brazil has P. chloris, the Andes of Colombia, Ecuador, and Peru P. tschudii, 
and Guiana P. chlorion, whilst P. griseiceps belongs to the mountains of Costa Rica. 
P. griseiceps is perhaps most nearly allied to P. tschudii, but differs in having the 
whole of the top of the head grey, and in the absence of the yellowish-white tips to the 
greater wing-coverts, innermost secondaries, and the rectrices. 
Our figure is taken from the type, which also served for that in Von Pelzeln’s and 
Von Madarasz’s Monograph on the Pipride. 
PIPRA. 
Pipra, Linneus, Syst. Nat. i. p. 338 (1766); Scl. Cat. Birds Brit. Mus. xiv. p. 292. 
Five of the eighteen known species of Pipra occur within the limits of Central 
America, only one of which, however, P. mentalis, is found as far north as Guatemala, 
British Honduras, and the southern portion of the Mexican State of Vera Cruz. The 
rest occur in Nicaragua and the countries lying to the south-eastward. 
Mr. Sclater divides the genus into three chief sections, based upon the coloration of 
the sexes. The first of these alone is represented in our region. 
Pipra mentalis has a much more elongated nostril than Péprites, which occupies the 
anterior lower portion of the nasal fossa and is slightly overhung by the membrane ; 
the subterminal notch of the tomia is not so distinct, but the rictal bristles are well 
developed; the wings, tail, and tarsi are much shorter. The sexes, too, are very 
differently coloured. 
a. Gula plerumque nigra (mento interdum flavo). 
a’. Vertex aut coccineus aut flavus.
