The length of the specimen from which the drawing was taken, is two feet; and it is about five inches and an half over at the broadest part, from thence tapering to the tail: the skin is rough, and the colour, in general, brown, palest on the under parts: over the eyes on each side is a prominence, or long ridge, of about three inches; under the middle of which the eyes are placed: the teeth are very numerous, there being at least ten or eleven rows; the forward teeth are small and sharp, but as they are placed more backward, they become more blunt and larger, and several rows are quite flat at top, forming a kind of bony palate, somewhat like that of the Wolf-fish; differing, however, in shape, being more inclined to square than round, which they are in that fish: the under jaw is furnished much in the same manner as the upper: the breathing holes are five in number, as is usual in the genus: on the back are two fins, and before each stands a strong spine, much as in the Prickly Hound, or Dog, fish: it has also two pectoral, and two ventral fins; but besides these, there is likewise an anal fin, placed at a middle distance between the last and the tail: the tail itself, is as it were divided, the upper part much longer than the under. 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.
