Cerithopsis eutrapela, Melvill & Standen. Melvill & Standen, Journ. Conch., viii., 1896, p. 301, pi. x, fig. 52. Three specimens, one mauve, the others white, from the lagoon beach of Cerithopsis electrina, sp. nov. (Fig. 26). Shell tall, slender, thin and translucent. Colour uniform pale amber, except a glassy white topmost whorl. Whorls nine in my example, whose tip is broken. Sculpture— on the earlier whorls proportionately fewer, on the last, six spiral alternately larger and smaller rows of crowd- ed gemmules, which also regularly succeed one another in longi- tudinal order, being continued across the suture from whorl to whorl and' ascending the spire obliquely. The individual gemmules, as seen in profile are much elevated, seen in full face are oval; those of the upper four rows of the last whorl are impressed and bisected by a shallow transverse groove, invisible in profile, but apparently doubling the transverse rows of gemmules when seen in full face. Above the first and below the fifth row, the longitudinal axis of each continues as a pillar, giving a fluted aspect to the broad and deep sutural excavation. The lowest row is swallowed by the suture of the subsequent whorl. Beneath the sixth row the shell is much undercut and then tapers to the columella. The aperture is nearly square with sharp outer lip, arched columella, and very short perpendicular canal. Length 4|, breadth 1| mm. One specimen from the lagoon beach of Funafuti. This appears to be distinguished from other Pacific Cerithiopsis by the more numerous rows of closely packed granules. Fig. Please note that the
