SMITH ON LAND AND FRESHWATER [NOV. 7, flavida, epidermide tenui induta, liris paucis nigris vel saturate rufis ornata ; anfractus circiter 7, convexiusculi, superiores spiralibus tribus cincti et zona nigra infra suturam picti, idtimus liris quinque cequalibus duobusque basalibus circa instructus, inter litis lineis incrementi conspicuis fortiter zona suturali nigra, cdteraque circa basim ornatus; apertura ovdlis, superne et infra paulo acuminata, longit. totius cequans ; peristoma tenue, marginibus callo tenui junctis, subreflexo. Longit. 15 millim., diam. 8; apertura 65 longa, 4 lata. Hab. Lake Mweru (R..Crawshay). This species is of the same character as Cleopatra emini, Smith (P. Z.S. 1888, p. 54), from the Albert Nyanza. It is somewhat larger, has less angular whorls, more keels or lirae, and a narrower basal rimation. The longitudinal sculpture or lines of growth are considerably more conspicuous. 19. MELANIA TUBERCULATA, Midler. Hah. Angoni-Land (A. Whyte). This species occurs in Tanganyika, Oukerewe, the Albert Nyanza, and has previously been recorded from Nyasa. 20. MELANIA NODICINCTA, Dohrn. Hab. Angoni-Land (A. Whyte). The single specimen which I assign to this species is, in some respects, intermediate between it and M. tuberculata. 21. MELANIA TURRITOSPIRA, Smith. Hah. Angoni-Land (A. Whyte). The specimen from this locality is twice as long as those figured in these ' Proceedings' for 1877, pi. lxxv. figs. 14,15. Those figures represent the surface too nodose. This species belongs to the so-called genus Micronyassia of Bourguignat. 22. MELANIA WOODWARDI. (Plate LIX. fig. 11.) Testa brevis, turrita, nigro-fusca, infra suturam pallidior; anfractus circiter 8, vix convexiusculi, costis obliquis 11-12 sulcisque transversis angustis paucis (in anfr. superioribus 2-3, in ultimo circiter 10) ornati, ultimus costis versus sensim obsoletis; apertura ovata, superne acuminata, totius i paulo superans; columella armata, alba, incrassata, reflexa. Longit. 19 millim., diam. 8; apertura 6g longa. Hab. Lake Nyasa. The single specimen here described was presented to the Museum by Mr. B. B. Woodward, after whom the species has been named. It is quite distinct from any of the other Nyasa forms. It is a short stumpy shell, of a very dark colour, with oblique coarsely nodose ribs, the nodules being produced by the spiral sulci cutting through the costae. |
