This beautiful Lizard is not uncommon at Port Jackson, where it is reputed a harmless species. Individuals vary much one from another, in respect to the length of the tail, as also in the colour of the markings; some having those parts marked with a pure silvery white, which in the above described are yellow. Genus CXXXV. Balistes.--Lin. Syst. Nat. BAG-THROATED BALISTES. 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.
