1. ALEUTERES MACULOSUS. _Richards._

Aleuteres maculosus, _Richards._ in Proceed. of Zool. Soc. 1840. p. 28.

FORM.—Oval, somewhat approaching to fusiform behind, very much

compressed. The greatest depth one-third of the entire length. Skin

covered with little granular points, terminating in very minute

bristles, and communicating a slight roughness to the touch, when

the finger is passed from tail to head. Snout rather prominent and

acute: jaws equal. Dorsal spine springing from above the middle of

the orbit of the eye; strong, with four rows of sharp prickles at

the four angles, pointing downwards, and very regularly set: second

dorsal spine very minute. The second dorsal and anal fins have been

lost in this specimen, and their form and number of rays cannot be

determined. The pectorals are small, each with twelve rays. Caudal

rounded, also with twelve rays.

Length 5 inc. 4 lines.

COLOUR.—“Mottled with pale blackish-green, leaving white spots.”—D.—In

its present state, the skin is nearly gone from long maceration in

impure spirit: such portions as are left accord well with Dr.

Richardson’s description, appearing of a mouse-grey, with darker

mottlings. There are three or four rather indistinct dark asciæ

across the caudal.

Habitat, King George’s Sound.

I have scarcely any doubt of this being the _A. maculosus_ described by

Dr. Richardson, in his recently published notes on a collection of

fishes from Van Diemen’s Land. Mr. Darwin’s specimen, which is in bad

condition, was obtained by him in King George’s Sound.
