DEFINITIONS

CONOTHRAUPIS
(Thraupidae; † Black-and-white Tanager C. speculigera) Gr. κωνος kōnos  cone; θραυπις thraupis  unknown small bird, perhaps some sort of finch. In ornithology thraupis signifies tanager; "Conothraupis, a new genus of Tanagers. — I have been kindly permitted to acquire in exchange from the Warsaw Museum a skin of Schistochlamys speculigera, Gould (P. Z. S. 1855, p. 68), one of the few Tanagers wanting in my series.  I am now convinced that the genus Schistochlamys (sive Diucopis) is not the proper position for this curious bird, which is remarkable for its straight gonys and but very slight incurved culmen.  I propose to remove it to near Arremon, where I think it will fit in better, under the new generic term Conothraupis (κωνος, conus, and θραυπις, tanagra); so that it will stand as Conothraupis speculigera." (P. Sclater 1880); "CONOTHRAUPIS, Scl. MS.1  Rostrum subconicum, tomiis medio profunde emarginatis.  Alæ  breves, subrotundatæ, remigum tertio et quarto omnium longissimis, secundo vix breviore.  Cauda apice rotundata.  Pedes debiles.  Habitus generalis Buarremonis.    *16. CONOTHRAUPIS SPECULIGERA.  ...  1Vide Ibis, 1880, p. 252." (Taczanowski 1880);  "Conothraupis P. L. Sclater, 1880, Ibis, p. 252.  Type, by monotypy, Schistochlamys speculigera." (Storer in Peters, 1970, XIII, p. 250).
Synon. Rhynchothraupis.
