DEFINITIONS

DUCULA
(Columbidae; Ϯ Mountain Imperial Pigeon D. badia insignis) Nepalese name Dukul for the imperial pigeons (cf. Hindi names Dunkul and Doomkul); "Genus or Sub-genus — DUCULA nobis. — DUKUL OF THE NIPALESE (genericé)    Character of the genus:—bill equal to the head, straight, cylindric, very feeble; both mandibles membranous for three-fourths from the gape; tip of the upper mandible gently inclined—of the lower, strongly compressed; nares broad, linear, obliquely transverse, central; their groove faint; their tect subtumid.  Wings short, not rounded, 3, 4, 5 quills sub-equal and longest; central primaries with their tips wavily truncated.  Tail 14, long, strong and square; tarsi very low, and plumed nearly to the toes laterally, less in front; toes depressed with broad flat soles; lateral fores sub-equal, hind large; nails strong, arched and acuminated; central and hind equal, lateral fores equal, less; orbits nude; plumage simple.  The above is a tedious charcater, but it is a distinct one. Those who love more summary proceedings may perhaps approve the following: "Bill and wings as in Goura; legs and feet as in Vinago."  ...  Lastly, though Ducula, like Vinago, be exclusively arboreal and fruit-eating; the latter is eminently gregarious—the former, almost a solitary.   Species new. DUCULA INSIGNIS. Great Ducula, nobis." (Hodgson 1836); "Ducula Hodgson, As. Res., 19, 1836, p. 160. Type, by monotypy, Ducula insignis Hodgson." (Peters, 1937, III, p. 42).
