Hob. Costa Rica, Tucurriqui [Arce ^"■*). 



A single specimen sent us by our collector Enrique Arce from Costa Eica 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. chloHon, whilst P. griseiceps belongs to the mountains of Costa Eica. 



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 Pipridse. 



PIPEA. 



Pipra, Linn^us, 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 Piprites, 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.
