"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." {158} The type of "_Pterodroma caribbaea_" is preserved in the Dublin Museum, and three specimens are in the British Museum. This bird is one of the rarest in collections, and all modern collectors have failed to obtain specimens. Quite recently (1906) Mr. B. Hyatt Verrill published a pamphlet entitled "Additions to the Avifauna of Dominica." In this unpaginated essay he said under the heading "_Aestrelata jamaicensis_": "Not uncommon (on Dominica), but seldom seen during the day. Breeds at La Bime, Pointe Guignarde, and Lance Bateaux, as well as at Morne Rouge and Scott's Head. In many of the above localities the musky odour of these birds is very pronounced when passing the cliffs, wherein they breed, on a calm evening. At dusk they may often be seen flying about the cliffs in company with myriads of bats that spend the day in the fissures and crevices. They are very difficult to procure, and although shot at repeatedly only two specimens have been obtained." From all former evidence we might have well considered this species to be extinct, but if Mr. Verrill's statement is correct it would be far from exterminated. I do not, however, know if the Dominica specimens have been compared with Jamaica examples, and if Mr. Verrill's determination (apparently made on Dominica) is therefore correct.
