At first sight, the above might be taken for the Prickly Hound-fish, or Squalus Spinax of Linnoeus, of which a good figure may be seen in Willughby’s Icthyol.  Tab.  B. 5. f. 1, but it differs, first, in having the prominent ridge over the eyes, of a great length; secondly, in the formation of the teeth; thirdly, in having an anal fin, of which the Prickly Hound is destitute; all these circumstances concur to prove it a new species.

This was taken at Port Jackson, but to what size it may usually arrive cannot be determined; perhaps not to a great one, as the teeth appear very complete.  Some sharks, however, of an enormous size have been seen and caught thereabouts, though of what sort cannot here be determined.

Genus CXXXI.  Squalus.—­Lin.  Syst.

Watts’s shark.

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.
