From one to two feet. Shaw.


{Form). Head very much compressed: mouth small: each jaw armed with eight large, broad, strong teeth, forming a continuous series: eyes round, placed high: first dorsal nearly in the middle of the back, consisting of three strong spines connected by a membrane, the first three times as large as either of the other two; when at rest, concealed in an osseous furrow on the ridge of the back; these spines are so articulated as only to admit of being elevated or depressed all together: second dorsal long, reaching nearly to the caudal: anterior portion of the abdomen armed with a sharp strong recurved bone, the extremity of which projects out of the skin in a backward direction; between this and the vent are several other much smaller, but moderately strong, serrated spines: anal similar to the dorsal, commencing behind the vent: tail becoming suddenly narrow, and terminating in a broad fin: pectorals small and round: ventrals wanting. Will. {Colours). "General colour violaceous gray, sometimes variegated both on the body and fins with blue or red spots: irides yellow; pupils blue." Shaw.

A single individual of this species, which is a native of the Mediterranean, as well as of the American seas, is recorded by Mr. Children to have been captured on the Sussex coast in August, 1827*. Not previously known as a British fish. Most of the species belonging to this genus inhabit the Tropics.
