. 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. APPENDIX— 559 OiECUM AMALTHRANUM, Sp. HOV, (Fig. 75.) Shell small, a twisted cone, performing about a third of a revolution, rapidly enlarging. White very glossy, with about twenty, faint rib rings. Aperture circular, slightly contracted behind the everted lip. Septum gradate, with three steps, arising deep within the collar, peaked on the outer side. Length '76; breadth at aperture •34 mm. Two examples dredged at 36 fathoms, north of Pava Islet. The contour of this species isolates it from any co-generic type. Caecum legumen, sp. nov. (Fig. 7G.) Shell pod-shaped, arched on one side, nearly straight on the other ; rounded in transverse section on the arched side and flattened on the straight. Colour white. Sculptured by fine growth rings, surface glossy and shining. At the aperture slightly contracted, mouth oval, flattened on one side. Septum much exserted, peaked on the curved side. As foreshortened to show the aperture in my drawing, the shell has a quaint resemblence to a tobacco pipe. Length 1-5; breadth 64 mm. Dredged at 36 fathoms N. 30° W. of Pava Islet and again at 150 fathoms oft' Beacon Islet (Funamanu). The only species at all resembling this, figured in Tryon's Manual, is C. nitidum, Stimpson, than which it is less inflated. Triforis asperrimus, Hinds. (Fig. 77.) Hinds, Ann. Mag. Nat. Hist., xi., 1843, p. 18 ; Try on, Man. Conch., ix., 1887, p. 181, pi. xxxviii., fig. 6. A single, probably immature, specimen of twelve whorls, in length 2-92 and in breadth -56 mm., which was dredged in 36 fathoms, north of Pava Islet is thus doubtfully determined. The species appears not to have been seen since Sir Edward Belcher dredged his unique specimen in eight fathoms on the Papuan Fig. Please note that these images are extracted from scanned page images t
