Show 482 MR. E. A. SMITH ON NEW SHELLS. [Julie 1 5, longitudinally minutely striated, a feature observable only under lens. The specimen described is in the collection of Dr. J. Percy, F.R.S. LATIRUS NAGASAKIENSIS. (Plate XLVIII. fig. 7.) Testa crassa, fusiformis, rotunde plicata et spiraliter lirata, costis nigro-fuscis, interstitiis pallide rufis, liris pallidioribus vel Anfractus circiter 12, convexiusculi, sutura profunda undulata sejuncti, costis vel plicis 8 latis, rotundatis, paulo obliquis, spiram subregular iter continuis instructi, liris transversis supra costas prominulis (in anfr. superioribus 3, in ultimo circiter et lineis elevatis filiformibus interjacentibus cincti. Anfr. ultimus superne rotundatus, infra medium contractus, ad basin anguste perforatus, costis inferne attenualis subobsoletis. Apertura fusco-albida, cum canali longitudinis totius |- adeequans, intus tenuiter lirata. Columella callo fusco-albido induta, superne parum arcuata, ad basin obliqua, in medio plicis tenuibus tribus levissime elevatis instructa. Canalis obliquus, vix reflexus. Long. 60 mill., lat. 22. Hab. Japan (Mr. Maries). This species may readily be distinguished by its striking painting. The swollen plicae, which are about twice as broad as the interstices, are of a rich chocolate-brown, whilst the interlying spaces are quite pale. L. varicosus is somewhat similarly coloured, but is less robust, the plicae being narrower and the spiral lirae more numerous. L. craticulatus is more cylindrical, has less pronounced costae, coarser spiral ridges, and is differently coloured. One specimen has a distinct transverse tubercle at the upper part of the columella, but in the other it is less developed. CYPR^A DECIPIENS. (Plate XLVIII. figs. 8, 8«.) Testa ovata, antice angustata, alta, in dorso gibbosa, inferne fere plana, superne pallide olivaceo-fusca, maculis irregularibus valde saturatioribus guttata et variegata, versus basin colore auran-tiaco- rubro suffusa, infra eodem colore picta. Apertura angusta, intus alba. Anfractus ultimus intra aperturam omnino niveus. Dentes labri circiter 20, mediocriter validi, columellares minus distincti, anteriores quinque vel sex cceteris magis producti. Sulcus columellaris antice latus, haud profundus. Long. 52 mill., diam. 36, alt. 32. Hab. North Australia (Mr. Jamrach). At a first glance this shell, unfortunately in a worn state, might very naturally be considered a dwarfed and peculiarly coloured variety of C. thersites; and it is impossible to affirm with certainty that such may not really be the case. Certain distinctions, however, present themselves, which, if constant, would certainly entitle this form to specific rank. In the first place, it is considerably smaller than any examples of C. thersitesl have seen; nor has Mr. G. B. Sowerby, jun., who is thoroughly acquainted with the variation of the species of this genus, ever had one of such small dimensions come under |
