Violaceo-niyra : pilei dimidio antico et abdomine toto saturate castaneo- aureis : subalaribus et remigum marginibus internis albis: rectricibus omnino nigris immaculatis. Long, tota 3*5, alca 2*1, caudce 1*2. flab. Demerara (Wilkens). Mus. P. L. S. Sclater's collection contains a single skin of this Euphonia, which belongs to the group of E. concinna. It is most nearly allied to E. saturata (Cab.)1, having a similar chestnut tinge on the abdomen, which, however, is even more strongly developed. But it differs from E. saturata in that only the front half of the top of the head up to the eyes is yellow, instead of the whole cap. The type specimen of this species having been received in exchange from the Bremen Museum, we propose to call it after its worthy Director Dr. Finsch. The collector's name is stated to be Wilkens. 2. PHEUCTICUS CRISSALIS, sp. nov. Pheucticus aureiventris, Scl. P.Z. S. 1858, p. 551. Supra niger, uropygio flavo nigro variegato: interscapulii quoque plumis intus flavo transfasciatis : speculo atari et maculis tectricum alarum, secundariorum et caudee tectricum supe-riorum albis : subtus aureo-flavus, in pectoris lateribus parce nigro striatus, crisso albo : cauda nigra, hujus rectricibus tribus utrinque externis plaga quadrata alba in pogonio interiore ornatis : subalaribus flavis : long, tota 7'7, ala? 4*5, caudee 3*6. Hab. Ecuador, Riobamba (Fraser) ; Sical (Buckley). Obs. Proximus P. uropygiali, sed gutture aureo et crisso albo distinguendus. In describing Ph. uropygialis (P. Z. S. 1870, p. 840) we observed that two skins obtained by Mr. Fraser at Riobamba, in Ecuador, and originally referred to P. aureiventris by Sclater, might possibly belong to P. uropygialis. It now appears, however, from additional specimens of the same form recently obtained by Mr. Buckley in the same district, that the species of the highlands of Ecuador is quite distinct. This, therefore, will make a sixth species of Pheucticus to be placed between P. tibialis and P. chrysogaster'1. 3. OCHTHCECA LEUCOMETOPA, sp. nov. Ochthceca leucophrys, Scl. & Salv. P. Z. S. 1867, p. 986 ; 1868, p. 569; 1869, p. 154; & 1874, p. 677; Scl. P.Z.S. 1871, p. 750; 1873, p. 780. Supra murino-brunnea, dorso postico rufescenti lavato: super- 1 Phonasca saturata, Cab. J. f.
