1887.] 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 

 bauds 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 C. crassiuscula 

 is identical with his C. sulculosa, an East-Indian species.

Common in the mud in mangrove-swamps, and probablv 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, S])iral, 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 C. crassiuscula, with the addition, in old specimens, of a 

 small denticle in the labial siuus. Lenoth 8 to 10 millim.
