The middle of the stomach is covered with a fleshy ring, armed with horny laminae as sharp as a knife. The common species is found on Fuciis natans, or gulf-weed, wherever this appears. The Glaucus, Forster, Have the elongate body and the vents as in the preceding ; four minute conical tentacula ; and on each side [two or] three branchiae, each formed of long fringes ar- ranged like a fan, and by whose means they swim. They are little charming Molluscs of the Mediterranean and Indian Ocean, agreeably painted with azure-blue and silver, and swim with great quickness on their backs. Their anatomy closely resembles that of Tritonia. The species have not, as yet, been satisfactorily distinguished. The Laniogerus, Blainv., has, on each side, two series of little plates, finely divided in a pectinate manner, which a
