The type of C. breve came from Tongatabu. The shell does not seem to have been again observed. Cerithium spiculum, sp. nov. (Fig. 21). Shell narrow, subulate, with a sharply-pointed spire and a rounded base. Colour dull white, dis- tantly, faintly, irregularly, and minutely spotted with chestnut. Whorls eleven, slowly increasing, somewhat turreted, flattened. Sculpture—on the uppermost whorls the spiral ridges are tuber- culated by longitudinal plications which rapidly diminish as the growth proceeds. On the last whorl their influence is barely perceptible in faint, shallow, longitudinal undulations. A stout varix occurs a third of a whorl behind the aperture ; from four to ten, raised, spiral cords encircle each whorl, in the interstices of which are fine spiral threads. Aperture perpendicular, oval; outer lip straight and sharp; canal very short, turned abruptly outwards. Length 11, breadth 4 mm. Two specimens were obtained in the outer beach of Nukulailai. This form appears allied to C. lacteum, Kiener,* from which it differs by smaller size, narrower outline, and absence of granula- tions. Cerithium strictum, sp. nov. (Fig. 22). Shell narrow, elongate, tapering in a slender spire and blunt anteriorly. Colour white, irregularly longitudinally splashed with chestnut. Whorls seven, the upper angled, the last straight. Sculpture— round the angle of the upper whorls runs a line of tubercles, of which eleven occur on the penultimate. Very slight longitudinal undulations, hardly to be called ribs, extend from these tubercles across the whorl ; both vanish before attaining the las
