Dorsals remote; the second with the fourth and succeeding rays gradually decreasing: eyes closely approximating.

From two to three inches.
(Form). More elongated and tapering than the G. niger, and not so much compressed: greatest depth, in the region of the pectorals, contained six times and a half in the entire length: thickness the same as the depth: head depressed; snout short; lower jaw projecting heyond the upper: eyes full and prominent, closely approximating on the upper part of the head, the space between reduced to a shallow groove, less than one-fourth of their diameter: opercle large, of an irregular square form, with the lower angle rounded off; the ascending margin nearly vertical; reaching nearly to the base of the rays of the pectorals: scales small: first dorsal with the first four rays nearly equal; fifth and sixth decreasing; all inclining backwards: space between the dorsals equalling half the depth of the body: second dorsal with the first ray a little shorter than the second; second, third, and fourth, equal and longest; the succeeding rays gradually decreasing to the last, which is scarcely more than half the length of the third and fourth: anal answering to the second dorsal, commencing and terminating nearly in the same line; the rays, however, with the exception of the first, which is much shorter than the others, more nearly of a height: caudal nearly even.
B. 5; D. 6 - 11; A. 12; C. 13, and 2 short; P. 20; V. 12.
(Colours). Yellowish white, and somewhat pellucid; the back and sides obscurely spotted and mottled with ferruginous; three or four of these spots, larger than the others, are placed at intervals on the lateral line; that which is most distinct being just at the base of the caudal: rays of the caudal and dorsal fins spotted with the same colour, giving the appearance of transverse bars when the fins are close; anal and ventrals plain: opercle with silvery reflections.
Common on many parts of the coast where it is sandy, and often taken in the shrimp-nets. Is probably, however, frequently confounded with the next species. Pennant considers it as the Aphua Cobites of Wil-lughby, but as this last is represented as having seventeen rays in the second dorsal, this opinion is probably incorrect.
