There is also one Medi- terranean species. Cilaiidiiia Vaiiuxoniensis, Lea. Shell elongated, ovate-fusiform, thin and fragile, considerably trans- parent, pale fawn-color, in scnne specimens in- clined to greenish, and generally flecked with distant, pale spots; the surface is, in a measure^ coarsely granulated by the decussation of longi- tudinal and revolving lines, the latter of which are more distant from each other than the former, and become less and less distinct towards the anterior portion of the whorl: whorls 7 or 8, the apical ones smooth and forming a mam- millary tip; suture crenulated; aperture about one-half the length of the shell, nearly three times as long as broad; columella strongly arched, and scarcely glazed by enamel. Length of axis, 68'""'; breadth, 25'"'". Glandina Vanuicemensis, Lea, Trans. Am. PLilos. Soc, V, 84, pi. xix, fig. 78; Obs., i, 196 (1837).—Pfeif- FER, Symbolte, iii, 91.—Binxey, Terr.
