16. BuLiMULUs HELENA, Quoj aud Gaimard. (Plate XXII. 

 figs. 13, 13 a.) 



With this species I unite B./ossilis, 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. 



Hub. Sugarloaf Ridge and Quarry, aud the Barn (Turton). 

 Extinct (? living).

17. BuLiMULUs suBTRUNCATus, sp. uov. (Plate XXII. fig. 14.) 



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

 lineis incrementi ohliquis teiiuibus striata ; anfractus 7, 

 convexiusculi, sutura subprofunda sejimcti, nltimus oblique 

 declivis, sed prope labrum leviter asceiidens, apertura inverse 

 auriformis, longit. fofius | haud cequans ; labrum teniie, 

 antice leviter pattilum vel expansum; columella obliqua, recti- 

 uscula, callo tenui superne labro juncto induta, antice plus 

 minus subtruncata. 



Longit. ^\\ millim., diam. 12g ; apertura 14 longa, 7 lata. 



Hub. 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. BuLiMULUssuBPLiCATus (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 Peronceus. The Cochlicopa terebeiliim 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 exulatos (Benson). (Plate XXII. tig. 16.) 

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

 Remarkable for the distinct truncation of the collumella like 



Leptachatina.

20. BuLiMULUs turtoni, sp. nov. (Plate XXII. figs. 17, 17 <?.) 



Testa anguste perforata, ovato-conica, tenuissima, nitida,fusco- 

 cornea, strigis irregidaribus opaco-lacteis, longitudinaliter 

 picta ; anfractus 7, convexiusculi, lineis incrementi obliquis 

 striati, ultimus ad peripheriam rotundatus, in exemplis 

 juvenilibus obsolete angulatus ; apex subpapillaris ; aper- 

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