Description

{Form). Wider in proportion to its whole length than the Common Sole, and also somewhat thicker: greatest breadth (in a specimen eight inches long), not including the dorsal and anal fins, three inches, including both fins, four inches: head obtuse, shorter and wider: mouth arched: opercle formed externally of a single piece, circular in shape, and less deep: under surface of the head almost smooth, without any of the papillary eminences so remarkable in the Common Sole; the nostril on that side pierced in a prominent tubular projection, wanting in gg2 the other species: scales differing both in character and general arrangement; the appearance of them more strongly marked upon the under than upon the upper surface: lateral line straight, but not very strongly marked: tail narrower than in the Common Sole, though composed of the same number of rays:

Number of vertebra forty-three. (Colours). Upper surface a mixture of orange and light brown, freckled over with small circular spots of very dark brown, presenting a mottled appearance; tip of the pectoral black: under surface white. Yarr.

First obtained by Mr. Yarrell at Brighton, where it is said to be " occasionally taken with the Common Sole by trawling over a clear bottom of soft sand, about sixteen miles from the shore." Is known there by the name of Lemon Sole. Has since been met with, in a few instances, in the London market. Obs. This species is not the Pleuronectes Pegusa of Risso, as was at first supposed by Mr. Yarrell. It appears to be undescribed by any of the continental authors.
