T is surprising that the name jamaicensis has generally been adopted for this species, as Bancroft gave no description whatever. The first description is that of Carte, in 1866, which is as follows:—"Head, neck, back, and wings of a uniform dark sooty brown; vertex and external webs of the primaries a shade or so darker; abdominal feathers and under tail-coverts a shade or two lighter than those of the back; upper tail-coverts and basal portion of tail-feathers of a light grey or dirty white. The light-coloured patch on the rump is conspicuous when the wings are expanded, but completely concealed when they are closed. Irides dark hazel. Tarsi, toes, webs, and nails jet-black.

"Length about 12¾ inches; expanse of wings 34 inches; length from carpal joint to tip of first primary 10¾ inches; length of bill, measured from gape, 1⅝ inches; length of nasal tubes 5&frasl;16 inch; length of interval between nostrils and commencement of apical curve of upper mandible ¼ inch; length of tarsi 15&frasl;10 inches; length of toes, outer and middle, sub-equal 2 inches; length of inner toe 1⅝ inches. First and second primaries sub-equal, and about ½ inch longer than the third. Tail about 4½ inches long and round at extremity. The closed wings extend about 1½ inches beyond the tail. Hallux small, and in shape triangular."

"With respect to the habits of the bird, Mr. March has most kindly furnished me with the following interesting details:—

"It is a night-bird, living in burrows in the marly clefts of the mountains at the east and north-east end of the island. The burrows form a gallery 6 to 10 feet long, terminating in a chamber sufficiently commodious to accommodate the pair; from this they sally forth at night, flying over the sea in search of food (fishes), returning before dawn. It is often seen on moonlight nights and at sunrise running about the neighbourhood of its domicile, and sometimes crossing the road, regardless of the labourers going to their work. I know nothing of its nidification."
