A double cirrus in front of each eye: dorsal and anal fins connected by a membrane with the caudal.

(Form). Head and anterior part/of the body broad and depressed; towards the caudal compressed and tapering: snout very much produced, spatula-shaped, narrower and more flattened than the head; gape wide; jaws nearly equal, the lower one a little the shortest; both furnished with minute sharp teeth; lips a little reflected: length of the head rather more than one-third of the entire length: eyes lateral; the space between them equalling about twice their diameter; immediately in advance of the anterior angle of each a membranous cirrus with a second minute filament branching out from its base; behind the cirrus a small fleshy tubercle: gill-opening small: skin smooth and naked: pectorals large, placed immediately behind the gill-opening, and extending downwards to the lower surface of the body, where the rays become suddenly stronger, and the membrane, doubling forwards, passes on to unite with that of the opposite fin under the throat; the membranes of the pectorals thus united enclose a disk, and form an hemispherical cavity; behind this cavity is a second, larger, circular, concave disk, formed by the united ventrals: dorsal commencing beyond the middle of the entire length, and reaching very nearly to the caudal, with which its membrane is connected: anal shorter, commencing further back, united in like manner to the caudal: rays of both fins articulated but simple: caudal rounded: number of fin ray s,

(Colours). Dusky, or purplish brown, (according to Mr. Couch, sometimes crimson,) with minute inconspicuous spots; flesh-coloured beneath: on the nape, behind the eyes, two ocellated spots; " each consisting of a large obovate spot of deep purple, enclosed within a broad pale brownish ring, and embellished in the centre with a brilliant blue dot, or pupil *: " dorsal, anal, and caudal fins, bright purplish red.
First observed by Borlase on the coast of Cornwall, where it has been since noticed by Mr. Couch. Found by Pennant in the Sound of Jura; by Montagu† , in some plenty, at Milton, on the coast of Devonshire, adhering to the rocks at low water. Obs. All our English authors represent this species as having only eleven rays in the dorsal fin; and this is made by Fleming a ground of distinction between it and the L. Gouani of Risso, which is said to have a larger number. In the only two British specimens, however, which I have had an opportunity of examining, they amounted to no less than nineteen. Possibly we may have two species in our seas, which have been hitherto confounded ‡. I may add, that in the above specimens, although there were two filaments before each eye, the second was extremely minute compared with the first, and much smaller than represented and described by Donovan.
