. The atoll of Funafuti, Ellice group: its zoology, botany, ethnology, and general structure based on collections made by Mrs. Charles Hedley, of the Australian museum, Sydney, N. S. W. . THE MOLLUSCA—HKDLEY. 435 spire, the penultimate whorl has ten and those above a proportionate decrease; they are weak at the suture, which they barely sinuate, and gain in breadth and height as they cross the whorl, projecting over the suture beneath them. They do not cross continuously from whorl to whorl, nor do they regularly alternate; they grow evanescent on the last whorl and cease with a stout and heavy varix one-third of the whorl behind the aperture. In this latter space, reminiscences of them occur as tubercles on the angle and at the suture. On the last whorl about twenty fine spiral threads are evenly distributed between the suture and the anterior point of the shell; the uppermost of these ascend the spire and are alike prominent on ribs and interspaces. Aperture perpendicular, subtriangular ; columella sharply sinuate, anterior notch not produced into a canal; callus on body whorl slight; outer lip thickened slightly and reflected, angled sharply at the posterior insertion. Length 4|, breadth 2 mm. Seven examples from the lagoon beach. Perhaps this is a member of the subgenus Colina. Cerithium piperitum, Sowerby. Tryon, loc. cit., p. 144, pi. xxvii., figs. 31, 32. Mr. G. Sweet procured a few dead shells of this species at Funa- futi. It had previously been recorded from the Ellice by Schmeltz, and also from Upolu and Rarotonga. There are examples from Tahiti in this Museum. Cerithium obeliscus, Bruguiere. Tryon, loc. cit., p. 146, pi. xxvii., fig. 39. One specimen from the lagoon beach. Melvill and Standen report this from the Loyalties; Schmeltz from Fiji and Cook's Islands; and Smith from Tonga.* In this Museum it is represented from Cooktown and Port Curtis, Queensland, also New Caledonia, Lord Howe Island and Hawaii. Cerithium obeliscus, var. cedo-nulli, Sowerby
