As ordinarily constituted, it represents, in round num- bers 500 current species and 100 genera, of nearly all parts of the world, ex- cept Australia, but more particularly of the northern hemisphere and through- out America, where the group attains its maximum development.

(After Dixon.) birds has a bird-fauna of over 200 species ; and if it be away from the sea-coast, and conse- quently uninhabited by marine birds, about one-fourth of its species are Sylvicolidce and FringillidcB together â the latter somewhat in excess of the former. It is not easy, therefore, to give undue prominence to these two families. The FringillidcB are more particularly what used to be called " conirostral" birds, in dis- tinction from " fissirostres," as the swallows, swifts, and goatsuckers, " tenuirostres,'' as hum- ming-birds and creepers, and " dentii'ostres," as warblers, vireos, and most of the preceding families. The bill approaches nearest the ideal cone, combining strength to crush seeds, with delicacy of touch to secure minute objects. The cone is sometimes nearly expressed, but is more frequently turgid or conoidal, convex
