From two to three inches.


{Form). General form similar to that of the C. Liparis: body very much rounded as far as the vent, beyond which it becomes suddenly compressed: head more depressed than in that species, and much inflated at the gills: snout, jaws, and teeth, similar: eyes small, placed high: front of the head, above the upper lip, scalloped with about six indentations: rest of the head, and body, very smooth: dorsal fin commencing a little behind the nape, and extending to the base of the caudal, with which, however, it is not in any way connected; rays at first very short and inconspicuous, but gradually increasing in length to just before the caudal, where the fin is broadest, and presents a rounded appearance: anal similar, and likewise separate from the caudal: pectorals and ventral disk much as in the C. Liparis: vent about half-way between the posterior margin of the disk and the commencement of the anal fin:

D. about 26; A. about 24; C. 12; P. about 29*.

{Colours). "Purplish brown in appearance to the naked eye; but by the assistance of a lens, the ground-colour is dull orange, covered with minute confluent spots of the former: the under parts are paler, and about the throat and sucker white: irides golden; pupil dark blue." Mont.

Discovered by Montagu, at Milton, on the south coast of Devon, where a few specimens were obtained at extraordinary low tides, among the rocks. Has been since found on the coast of Ireland by Mr. W. Thompson of Belfast: also on the coast of Berwickshire by Dr. Johnston. Apparently a rarer species than the foregoing.
