Show 1875.] MR. G A R R O D O N T H E T R A C H E A OF CERTAIN DUCKS. 151 This species was also procured by Lieut. Liardet in the mountains of Taviuni. Native name Ai-sou. 5. CHRYSCENA VIRIDIS, sp. nov. Male. General colour darkish green; head soiled golden yellow without gloss; under tail-coverts bright chrome-yellow; thighs, lower part of belly, and vent French grey ; the green of the back and sides of the chest glossed with gold ; these feathers have the V-shaped termination as in Ptilinopus ; and the first primary shows a tendency to narrowing as in that genus. Primaries edged with yellow, secondaries brilliant green; the inner webs of both golden yellow, as is the underside of the flexure and the inside of the wing ; underparts less brilliant than the upper, except on the chest, where there is a beautiful green sheen in certain lights; bill blue-black, tip pale livid; legs very dark crimson ; iris yellowish. Length 7" ; wing 4" 6'" ; tail 2" 3'"; tarsi 10"'; bill 10'". Female. Less brilliantly coloured, especially about the head. I obtained this lovely species at Kandavu on the 8th of August, evidently breeding, the testes of the males being enormously developed. It fed on the berries of a species of banian, and appeared to be not very uncommon. One of the naturalists of the ' Challenger,' Dr. von Suhm, obtained several specimens, but wrongly identified it as C. luteovirens, which he did not procure. I agreed with him at the time, till I obtained specimens for myself, and, finding it in the full breeding-stage, came to the conclusion that m y first impression of it being C. luteovirens not in breeding dress must be erroneous. The acquisition of C. luteovirens in all stages showed me, beyond a doubt, that it is distinct; I therefore describe it as an addition to the genus Chryscena. I have been puzzled by the natives identifying the female of this and of 0. luteovirens with C. victor of Gould; but I think I may now affirm, from both native and European testimony, that the female and young male of that species are green, as are those of C. luteovirens. C. victor is more widely distributed than I at first thought; it has been obtained at Lanthala, Bua, Ngamea, and Taviuni. The natives call it "Bulindamu" at Kandavu they called C. viridis " Sokulu" on Ovalau they designate C. luteovirens by tbe name of " Buniaco." The Carpophagus and Columba vitiensis they call " Bube" (Rubey), and Phlegcenas stairi " Ngilu"*. 7. On the Form of the Lower Larynx in certain Species of Ducks. By A. H. GARROD, F.Z.S. [Eeceived March 2, 1875.] The present communication contains descriptions of the condition of the lower larynx in some rare members of the Anatida, which are not referred to in the works of either Mr. Eyton or Mr. Yarrell. * Italian vowels. |
