Diameter not much above one-quarter of the height, which is but three-eighths of an inch.'--(Mr. Sowerby.) The figure is taken from Mr. Sowerby's plate, no specimen so proper for" figuring having come under my notice. Locality.--In South Devon: Plymouth. 185. Loxonema Lincta, pi. 38, fig. 185 a, b. Character.--Ovoideo-conical, volutions convex, or rather tumid, covered with many equal sharp very slightly arched longitudinal striae. The last whorl is quite as long as all the rest of the spire. The disproportion of the whorls (owing to the last including and concealing so much of the penultimate), gives this shell its most obvious character, and suggests the probability that Buccinum imbricatum of Sowerby, from Devon, and Buccinum arculatum, of Goldfuss, from the Eifel, should be referred to this same genus. Locality.--In South Devon: Barton. 186. Loxonema Tumida, pi. 38, fig. 186. Ref.--Melania tumida. Phillips, Geol. of Yorkshire, vol. ii., pi. 16, fig-2. Character.--Turrited, volutions remarkably convex, with arched longitudinal striae. Var. a.--The striae very fine. This is the character of the specimens found in the mountain limestone of the North of England. /8.--The striae having the character of small furrows. This is the appearance of the Cornish specimens. Locality.--In Cornwall: South Petherwin. 187. Loxonema (?) Prterita, pi. 38, fig. 187 a, b, c. The distinctness of this form from all the other Gasteropoda of Devonshire, is evident; but there are no means to characterize it properly. The specimen marked 187 c, was found at Hope, near Torquay, and it shews the mouth pretty well, nearly agreeing with the aperture of Loxonema, as far as that is known. Locality.--In South Devon: Newton Bushel; Plymouth;...
