Piprites grisetceps Salvin, Proc. Zool. Soc. Lond. 1864, p. 583 (Tucurrique, Costa Rica).

6. GENUS CERATOPIPRA BONAPARTE 
Ceratopipra Bonaparte, Consp. Volucr. Anisod. p. 6 (Sep. ex : Ateneo italiano n° rr, August 1854) 
(type of the genus : Pipra cornuta Spix). 
Characters. This genus comes very near typical Pifpra, but is distinguishable by 
its larger bill, much longer tail, longer and more robust tarsus, and by the adult male having 
the feathers of the occiput much elongated so as to form a full nuchal crest. The bill is of 
the same shape as in Pifra, but stronger and perhaps more rounded along the culminal ridge, 
Wing as in Pifra, with the third primary longest, and the first about equal to the 
fifth. Tail nearly square, the median rectrix being scarcely shorter than the others, and 
about two-thirds of the length of the wing. Tarsus robust and covered with a single, long 
lamina, the scutellae being fused except on the lower end, near the toes. Feet flesh colour. 
Sexes different. The adult of is glossy black; top and sides of the head as well as the elon- 
gated nuchal crest and the thighs bright scarlet; axillaries and under wing coverts blackish 
brown, the latter with slight, pale yellowish edges. In C. cornufa the whole throat is scarlet, 
the bases of the feathers being whitish, while in the other supposed « species », C. iracunda, 
the throat is black like the rest of the under parts except a very small, red chin spot. As the 
only known specimen of C. iracunda was obtained on the Roraima Mountains where Withely 
also collected a number of specimens which do not differ in any way from ordinary C. cornuta 
of Brazil, it is more than probable that C. ivacunda is merely an individual aberration. 
The female of C. cornuta is of a dull olive green, paler on the under surface than on the 
back, like the 9 9 of some Pifra-species, from which, however, it can easily be distinguished 
by its much longer tail, tarsus, etc., etc. 
Geographical Distribution. British Guiana and Lower Amazonia (Obidos, Barra do
