From eighteen inches to two feet.
De script. (Form). Body deep, and at the same time remarkably thick and fleshy: back sharp and elevated, with a salient ridge of osseous tubercles, occupying the place of, and representing, a first dorsal fin; the tubercles ten in number, of a somewhat conical form, striated, and sharp-pointed: three longitudinal rows of similar tubercles on each side of the body; the first commencing a little above the eye, and extending nearly to the caudal; the second commencing behind the gills, and reaching to the same distance; the third, a short row of five tubercles, placed at the side of the abdomen, and terminating near the commencement of the anal fin: there are also two very short rows of tubercles, placed one on each side of the space intervening between the dorsal ridge and the dorsal fin: belly, included between the two rows of abdominal tubercles, flat: head short; forehead broad, rising very obliquely: mouth wide; lips thick and fleshy; jaws furnished with numerous small sharp teeth, besides which are some small rough tubercles on the pharyngean bones, and near the root of the tongue: nostrils single, tubular, about half-way between the mouth and the eyes: skin without scales, but every-where rough with small sharp points: second or true dorsal placed far behind; its length a little exceeding its height; extending to near the caudal, out leaving a small intervening space: anal answering to the dorsal: ventrals united, forming together a circular disk, with a funnel-shaped cavity in the middle: pectorals very large, passing downwards and forwards beneath the throat, and surrounding the disk of the ventrals:
B. 6; D. 11; A. 10; C. 12; P. 21. (Colours). Back and sides dusky olive, here and there tinged with reddish; belly crimson: caudal and anal fins purplish red, spotted with dusky: pectorals bright orange.
Var. ß. C. pavoninus, Shaw, Nat. Misc. vol. ix. pl. 310. "Back of a fine azure, deepening towards the ridge: the sides tinged with crimson: mouth, sides of the head, and all the under parts to the tail, of a delicate sea-green, with a silvery tinge on the cheeks, the pectoral fins, and the part of the body next the tail: irides likewise silvery; pupil black: fins and tail terminating in a fine pale yellow." Davies.
Not an uncommon species on many parts of the British coast, but taken in most abundance northwards. Spawns, according to Bloch, in March.
Power of adhesion, by means of the ventral disk, very great. Var. ß was taken near Bangor in Caernarvonshire, in 1797, and sent to Shaw by Mr. Hugh Davies of that place. It measured only six inches in length. Obs. The Lumpus gibbosus of Willughby* (Cyclopt. pyramidatus, Shaw†), characterized by a pyramidal hump on the back, and said to be found in the Scotch seas, owes its origin, in the opinion of Cuvier, to a badly-stuflfed specimen of the present species.
