The size of the fish figured in the plate is uncertain, as we have only obtained a drawing of it without any description.—­It agrees in many things with others of the genus, and does not greatly differ from one figured in Willughby’s Icthyologia, Tab. 1. 22. but has the body longer in proportion.  The erect horn or spine is placed over, and a little behind the eyes, as in Willughby’s figure, attended with two shorter ones directly behind the first:  the long spine is quite straight, sharp at the point, and deeply sawed on the back part.  Another singularity presents itself in this species, which is, a deep pouch-like appendage beneath the throat, in shape not unlike what is called Hippocrates’s sleeve, or rather a jelly bag.

This fish is found pretty commonly on the coast of New South Wales, and was called by the sailors the Old Wife, having much resemblance in many things to the species so named.  When skinned, it was thought pretty good eating.

A fish of new south Wales.

Of this fish it can only be said, that the ground colour is much the same as that of our mackarel, marked with several round, blue and white spots; and that, in the plate, it is represented faithfully from a drawing by Daniel Butler sent from New South Wales, where it is in great plenty, and is thought to taste much like a dolphin.  As to the genus, it is difficult to say with certainty to which it belongs, as it is deficient in the characteristics of those generally known; it is therefore left to the reader to settle this matter according to his own opinion.

Genus CXXXI.  Squalus.—­Lin.  Syst.  Nat.

Port Jackson shark.

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.
