Rostrum forte, breve, latum, altitudine ad basin longitudinem æquans; mandibulis integris, superiori in frontem angulariter extendente cumque eo circuli arcum formante.  Alæ mediocres, subacuminatæ; remigibus, 1ma brevissima subspuria, 2da 3tia 4taque fere æqualibus longissimis.  Cauda gradata, lanceolata; rectricibus mediis cæteras paullo longitudine superantibus.  Pedes mediocres, subgraciles.   The peculiar spear-head form of the tail, and the ridge of the upper mandible and the forehead, forming a segment of the same circle, together with the habits of the following species, afford sufficient characteristics to justify their separation from the genus Fringilla of M. Temminck. The Gros-bec longicone of the Pl. Col. 96. (Emb. quadricolor, Lath.) belongs to the same group.   109. Lonchura nisoria. Fringilla nisoria, Temm. Gros-bec épervin. Pl. Col. 500.
