longitudinally minutely striated, a feature observable only under a 

 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 paUidioribus vel alhidis. 

 Anfractus circiter 12, convexiusculi, sutura profunda undulata 

 sejuncti, costis vel plicis 8 latis, rotundatis, paulo obliquis, supra 

 spirnm subreguJariter continuis instructi, liris transversis supra 

 costas prominuUs {in anfr. superioribus 3, in ultimo circiter 12) 

 et lineis elevatis filiformibus interjacentibus cincti. Anfr, ultimus 

 superne rotundatus, infra medium contractus, ad basin anguste 

 perfora.tus, costis inferne attenuatis subobsoletis. Apertura 

 fusco-albida, cum canali longitudinis totius y acfcequans, intus 

 tenuiter lirata. Columella callo fusco-albido induta, superne 

 parum arcuata, ad basin obliqua, in medio plicis tenuibus tribus 

 levissime elevatis instructa, Catialis obliquus, vix refiexus. 

 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 

 piile. L. varicosus is somewhat similarly coloured, but is less 

 robust, the plicee being narrower and the spiral lirse more numerous. 

 L. craticulatus is more cylindrical, has less pronounced costse, 

 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^ea decipiens. (Plate XLVIII. figs. 8, 8a.) 



Testa ovata, antice angustata, alta, in dorso gibbosa, inferne fere 

 plana, superne pallide olivaceo-fusca, maculis irregularibus valde 

 saturatiorihus guttata et variegata, versus basin colore auran- 

 tiaco-rubro siiffusa, infra eodeni colore picta. Apertura angusta, 

 intus alba. Anfractus ultimus intra aperturam omnino niveus. 

 Denies labri circiter 20, mediocriter validi, columellares minus 

 distincti, anteriores quinque vel sex cateris magis producti. 

 Sulcus columellaris antice latus, haud profundus. 

 Long. 52 mill., diam. 30, alt. 32.

At a first glance this shell, unfortunately in a worn state, might 

 very natxirally 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. thersites! 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
