INTRODUCTION. Genus CatiipHiox, Bore. ps the very commonest of the frill-necked Humming-Birds is the C. amethystina. It is more widely since it inhabits all the countries from Braz I have some doubt as to the propriety of so doing. The Perha spread than many other species, il to Venezuela. In this genus I have also placed the C. Mitchelli ; but throats of the two birds, although beautifully coloured, are not luminous. Vol. III. Pl. 159, 178.

It will not, however, be necessary to give a separate figure of it. Specimens from Minas Geraes are certainly more diminutive than from elsewhere. 180. CaLnutipHiox?
