The description below I have quoted (somewhat abridged) from Robinson’s MSS., who has given an elaborately coloured figure of the species in his drawings. I have never met with it, but I think Mr. Hill has; for he has assured me of the existence of two true Nyctibii in Jamaica, besides the common Potoo; and two Caprimulgi, besides the Piramidig. I knew not exactly which species are alluded to in the following extract from a letter of Andrew Gregory Johnston, Esq., of Portland parish, a mountain region, to Mr. Hill. “We have two birds called Patoo; one white, the other brown. The first resembles the Scritch-Owl of Europe; the last is smaller; it is dark brown, and makes a noise by night, (and occasionally by day) half guttural, half pectoral or ventral, sounding the monosyllable _wow_, at short intervals. I have seen a brown Patoo taken by a negro boy in mid-day from a branch of a mango tree, with a noose fastened to a short stick. It was young, but a flier. Its mother came to look for it, and we caught her, and kept her some days. When liberated she would not move off many yards from the house, but was seen daily for a few weeks. When a prisoner it would eat cockroaches thrown down to it, and if handled was cruel and spiteful, otherwise quiet and apparently very gentle. There are plenty of them here. I listen to their sulky _wow_, often in the watches of the night.” Perhaps the present species may be “the small wood Owle” of Sloane, ii. 296. +Fam.+—HIRUNDINIDÆ.—(_The Swallows._) RINGED GOWRIE.[12] _Acanthylis collaris?_ ? _Cypselus collaris_, +Pr. Max.+—Temm. Pl. col. 195. [12] “Length 8¹⁄₂ inches, expanse 20, wings reaching 2¹⁄₄ beyond the tail, tail 3, rictus ⁶⁄₈, beak from feathered part to tip ³⁄₈, tarsus ⁶⁄₈, middle toe ¹⁄₂, claw ³⁄₈, inner toe equal to the middle one. “Irides deep hazel [“blacker than the pupil,” Mr. Johnston;] beak black, polished, a little hooked; nostrils large, oval: eyes large, deep sunk in the head, with remarkably large eyebrows; toes three before and one behind, covered as well as the tarsi with blackish purple scales; claws black, polished, hooked, and compressed; tibia feathered to the tarsus. Head, throat, wings, tail, and belly brown; the back and tail more inclining towards black, as also the long quill-feathers. The breast partly white, which was continued round the neck, like a ring: the head large, like that of Edwards’s Whip-poor-will. Fore part of the eyebrows tipt with white.” “As this bird seldom alights, it is furnished with two supernumerary bones, which are placed on the superior and exterior part of the leg; the skin that covers them is of an obscure flesh-colour; they are of an oblong ovated form, one fourth of an inch long; and as the bird hangs upon a wall, rock, &c., by his claws, these bones are pressed close to it, and the leg thereby secured from harm.
