256 Rev. H. Clark on Dejean's Genus Coelomera. 3. Paludina affinis. P. testa couico-ovata, suboblate perforata, solidula, Hneis spiralibus impressis, subtilissimis vel obsoletis, fusco-cornea, fasciis rufo-fuscis 3-6 picta ; spira convexo-conoidea ; anfr. 5, convexi, sutura mediocriter profunda divisi ; apertura paulum obliqua, subcircu-laris, angulo supero rotundato ; peristoma subcontinuum, iterate nigro limbatum. Alt. 27, diam. major 23, mln. IS^, apert. alt. IC^, latit. IS^-mill. Operculum normale. Australia; collected at Fitzroy river and near Port Essington by Capt. Wickham^ R.N. ; other specimens by J. R. Elsey, Esq. (B.M.) This species stands nearly in the same relation to the pre-ceding as P.fasciata, Miill. (P. achatina, Drap., Lam.), to P.vivi-para, Miill., the chief difference being in the outlines of tlic vi^horls; besides, the spiral sculpture is much less developed in P. affinis. The bands are almost the same as in P. australis; but there is a third, secondary band between the second and third principal ones. This species varies somewhat in the elevation of the spire, several smaller specimens found at the same localities having it more produced, and therefore being of a more oblong form, and having a relatively smaller aperture. The dimensions of one of these are us follows: — altit. 19^, diam. maj. 15, min. 12, apert. alt. 11^, lat. 9 mill. 3, Paludina polit a. P. testa globoso-couica, perforata, nitida, lineis spiralibus impressis subtilissimis baud valde confertis sculpta, corneo-lutea vel pallide carnea, fasciis nullis; spira conoidea, subgradata; anfractus 5, inflati, valde convexi, sutura mediocri ; apertura paulum obliqua, ovata, angulo supero modice acuto ; peristoma plerumque con-tinuum, iterate fusco limbatum. Alt. 22A, diam. maj. 19, min. 17, apert. alt. 13, lat. 11 mill. Operculum normale, rufum. South Australia, on the Balonne river. New South Wales ; found by John Macgillivray. Other regularly decollated speci-mens, of a brighter red colour, in Lake Alexandria, found by Mr. Strange. (B.M.)
