(Thraupidae; Ϯ Rufous-crested Tanager C. verticalis) Genus Creurgus Morris, 1837, shrike; ωψ ōps, ωπος ōpos  appearance; “123. CREURGOPS VERTICALIS, sp. et gen. novum. (Pl. CXXXII. fig. 2.)   CREURGOPS *, genus novum, Lanioni et Trichothraupidi affine, sed rostro diverso. Rostrum breve, crassum, culmine versus apicem incurvo, gonyde vix ascendente, commissura modice arcuata, mandibula superiore dente mediali distincto et altero finali instructo; vibrissis rictalibus nonnullis: alæ modicæ, caudæ tertiam partem attingentes, remigibus secunda, quarta et quinta æqualibus et longissimis, prima his paulo breviore: cauda longa, apice quadrata.  ... This peculiar Tanager seems to belong to the neighbourhood of Lanio, Tachyphonus and their allies, and, like the former, has a very sharply defined notch about two-thirds of the distance along the edge of the upper mandible. But the bill is otherwise very different from that of Lanio, being much shorter, broader, thicker, and more swollen, with the culmen much arched towards the tip.  ...  *κρεουργος lanius, et ωψ facies.” (P. Sclater 1858).
Synon. Malacothraupis.
