ELLIOT ON THE GENUS PTILOPUS. 567 of the upper and under surface bright deep green ; the wing-quills deep golden green, mesially shaded with black ; the inner webs of the primaries black towards the middle and basal portion of the feather. The three inner secondaries and their corresponding coverts of the larger series only have an oblique oblong blotch of bright golden yellow at their tips, which on the secondaries is confined to the outer web only, the smaller wing-coverts at the bend of the wing adjacent to the scapulars having a roundish, crescentic or cordate spot of white (?) near the tips of the feathers; some show a green shaft-line and a margin of green round the tip of the feather ; under wing-coverts green; the outer series ashy; under surface of the wings ashy brown ; under surface of the tail ashy brown, becoming lighter towards the base, and crossed conspicuously near the tip with a band of light ashy grey; upper surface green, the grey band not so conspicuous ; the inner portion of the legs and lower part of the abdomen yellowish (much faded); under tail-coverts yellow, blotched with oblong marks of green on inner webs; the thighs, outer feathered portion of the legs, and the flanks bright green, like the rest of the body; tail of 14 feathers, square, even ; of the wings, the third, fourth, and fifth feathers are nearly equal and longest; bill, legs, and feet bluish lead-colour; tarsi not feathered to the toes, lower portion scaled in front. Total length 9*5 inches, wing 6*3, tail 3; bill from forehead 0*8, from gape 1 ; tarsus *95." 59. PTILOPUS LAYARDI. Chrysomas viridis, Layard, Proc. Zool. Soc. 1875, pp. 151, 4 3 7 ; Finsch, Proc. Zool. Soc. 1877, p. 736. Native name Sokulu (Layard). Hab. Kandavu, Fiji Islands. This apparently very distinct Pigeon was described by Layard (Z. ci) from specimens obtained by himself at Kandavu. He at first identified it, as he tells us, with P. luteovirens, but afterwards, having obtained it in the full breeding-dress, saw that his first impression was an erroneous one, and then conferred upon the species the name of viridis. Several specimens of this pretty Dove are in the collection of the 'Challenger' Expedition, which, through the kindness of m y friend Dr. Sclater, I have had the opportunity of examining. They are all in the adult dress, with greenish-yellow head, and entirely green body relieved only by the yellow of the under tail-coverts. The feathers of the back are slightly inclined to the lanceolate form of those of P. luteovirens; but the two species cannot well be confounded together. As I do not consider that the birds included in the term Chrysoznas possess any characters that should properly separate them generically from Ptilopus, it will be impossible to retain the name of viridis given to this species by Mr. Layard, as there is already, unfortunately, a species of this group so named, described originally by Linnaeus. I have therefore substituted the name layardi, in justice to m y friend, who has, in his researches among the birds of the Fiji Islands, exhibited the same energy and |
