 white bands. 



154. exilis (f. 452), Marrat. — 0. lanceolata similis, sed 

 plica elevata prope tertninum deficienti. — The Editor regrets 

 that he has failed to express in fig. 384 the raised fold on 

 the inner edge of the columella, which would distinguish 

 0. lanceolata, Reeve, from this shell.

 tiuscula, inter areas albas insequales fusco longitudinaliter 

 lineata ; spira, elevato-conica, anfractibus calloso-convexis,

 pureo fasciato ; columella postice unimaculata, medio subar- 

 cuata, antice unidentata, biplicata ; apertura intus griseo- 

 purpurea; labio tenui, antice dilatato. — This species varies 

 very little; its purple interior and elongated form, as well as 

 its colour, serve to distinguish it.

 fulva, supra medium albo unifasciata, ad suturam et in fasciis 

 duabus lineatim rubro maculata ; spira 'elongata, anfractibus

 tura alba; labio tenui, antice expanso. — Rather more ob- 

 tuse in form, callous in the columella, and coarser in the
