266 MR. E. A. SMITH ON THE l-^V^' ^j 



16. BuLiMULUS HELENA, Quoj and Gaimard. (Plate XXII. 

 figs. 13, 13 a.) 



With this species I unite B.fossilis, of Sowerby, and B. seale- 

 ianus of Forbes (PI. XXII. fig. 13 a). Typical specimens are of the 

 same general form as the S.-American B. proteus, Broderip, and 

 have somewhat similar granular sculpture. 



Hab. Sugarloaf Ridge and Quarry, and the Barn (Turton). 

 Extinct (? living).

17. BuiiiMTJLUs suBTRUNCATus, sp. nov. (Plate XXII. fig. 14.) 



Testa suhfossilis, elongato-ovata, superne acuminata, iviperforata, 

 lineis incrementi obliquis teimibus striata ; anfractus 7, 

 convexiusculi, sittura subprqfunda sejuncti, ultimus obliq^iie 

 declivis, sed prope labrum leviter ascendens, apertura inverse 

 auriformis, longit. totius ^ hatod cequans ; labrum tenue, 

 antice leviter patuJum vel expansum; columella obligrua, recti- 

 uscula, callo tenui superne labro juncto indtota, antice plus 

 minus subtruncata. 

 Longit. 31-| millim., diam. 12| ; apertura 14 longa, 7 lata. 

 Hab. Side Path, common (Turton). Extinct. 

 Although not particularly like B. virgulatus, Fer., it is perhaps 

 more allied to that species than any other. The subtruncation of 

 the columella, however, is more pronounced.

18. BuLiMULUs suBPLiCATUs (Sowerby). (Plate XXII. fig. 15.) 



Hab. Sugarloaf Ridge, common (Turton). Extinct. 



Quite distinct from any other known species and of elongate form 

 like the section PeroncBus. The Cochlicopa terebellum of Sowerby, 

 a slightly more slender form, is evidently merely a slight variety 

 in which the plications at the suture, probably through the 

 worn condition of the specimens, appear to be less developed.

19. EuLiMULUs EXULATUS (Beusou). (Plate XXII. tig, 16.) 



Mab. Sugarloaf Ridge, common (Turton). Extinct. 

 Remarkable for the distinct truncation of the coUumella like 

 Leptachatina.

20. BuLiMULus TURTONi, sp. uov. (Plate XXII. figs. 17, 17 «.) 



Testa anguste perforata, ovato-conica, temdssima, nitida,fiisco- 

 cornea, strigis irregularibus opaco-lacteis, longitudinaliter 

 picta ; anfractus 7, convexiusculi, lineis incrementi obliquis 

 striati, ultimus ad peripheriam rotundatus, in exemplis 

 juvenilibus obsolete angulatus ; apex subpapillaris ; aper- 

 tura ovata, superne acuminata, longit. totius ^ haud cequans;
