Show 887.] MOLLUSKS OF THE VITI ISLANDS. 297 millim. long. It is of different shades of chestnut-brown, white, corneous, fulvous, frequently with from one to four pale transverse bands on the body-whorl, and more rarely with a sutural livid band. Aperture pale fulvous, brownish or white, and the lip light fulvous or white. I am inclined to believe this species is diffused throughout the New Hebrides, Solomon Islands, and, perhaps, extends its range into the East Indies. I am sure Samoa is the eastern limit of the genus Cassidula ; Martyn's C. nucleus, which is erroneously quoted as a Tahitian species, does not inhabit that group. I am also strongly inclined to believe Mousson's O. crassiuscula is identical with his G. sulculosa, an East-Indian species. 3. CASSIDULA FALUDOSA, Garrett. Ophicardulus paludosus, Garrett, Amer.

(Auric.) iv. p. 327. Common in the mud in mangrove-swamps, and probably generally distributed in the group. I took a few examples at Upolu, one of the Samoa Islands. A small, solid, ovate, whitish, yellow-corneous, or chestnut-brown species, with fine, spiral, incised, punctured lines and a carinated base. Spire convexly-conical, and more produced than in the preceding species. Aperture white, tawny, or fulvous, with the dentation of O. crassiuscula, with the addition, in old specimens, of a small denticle in the labial sinus. Length 8 to 10 millim.
