This, we believe, is a species which has hitherto escaped the researches of our Icthyologists. The length of the specimen is nineteen inches: the head is broad, and angular in shape; but the body rounded, and nearly equal in its dimensions for above half the length, when it suddenly grows very small, and so continues to the end of the tail: the colour of the body is brown in different shades, and there are three rows of large pale spots, of an irregular shape, most of them dark within; one row passes down the middle, the others are on each side; besides which there are others below them less conspicuous. The mouth is placed nearer the end of the head than in most of the genus, and furnished in the front with nine sharp crooked teeth, in three rows, and a great number of small ones on each side. The eyes project considerably above the rest of the head, and are placed on the upper part of it; the space between is hollowed or sunk in: at the most forward part of the head are two cartilaginous appendages, jagged at the end, with four others, nearly similar, on each side between the first and the breathing holes: the pectoral fins are placed beneath these last; the abdominal about the middle of the body; and the anal, more than half way between the last and the tail; besides which, the under part is finned from that place to the end: on the upper part of the body are two fins, both placed uncommonly far back, as in the figure. This fish was met with in Sydney Cove, Port Jackson, by Lieutenant Watts, and is supposed to be full as voracious as any of the genus, in proportion to its size; for after having lain on the deck for two hours, seemingly quiet, on Mr. Watts's dog passing by, the shark sprung upon it with all the ferocity imaginable, and seized it by the leg; nor could the dog have disengaged himself had not the people near at hand come to his assistance. Order II. Pies. Genus XXIII. Kingsfisher. GREAT BROWN KINGSFISHER.--Lath. Syn. ii. p. 603, No. 1. The length of this species is from sixteen to eighteen inches: the bill, three inches and an half, or even more; the upper mandible is brown, and the under white, but brown at the base: the head is pretty full of feathers, sufficiently so to form a crest when erected; the colour whitish, and most of the feathers either tipped or crossed with black: the neck and under parts of the body are much the same in colour, crossed on the sides with dusky lines: over the forehead the colour is dusky brown, almost black, passing backwards in an irregular shaped streak a good way behind the eye: the back, and major part of the wing, is black or dusky, but the middle of the wing is of a glossy blue-green, as is also the lower part of the back and rump: the tail is barred with pale rust-colour and black, inclining to purple, and towards the end whitish: the legs are of a dusky yellow, the claws are black.
