Head crested, the feathers rufous, varied with black. Wings, and elongated forked tail raven-black, immaculate. * * * * * For this beautiful and extraordinary bird I am indebted to Miss E. Yeates, of the Dingle near Liverpool, who received it from South America. Its general habit clearly points it out as belonging to the _Baccavorae_ or Berryeaters, apparently connecting the genera _Procnias_ and _Pipra_, where Temminck with much judgement has also placed it, in the new edition of his _Manuel d'Ornithologie_ just received, and before reading which I had considered the genus as unpublished.
