OLIVA. 23 



110. Beaziliana (f. 278, 279), Lamareh. — Subconica, pal- 

 lide fulva, albo strigata, lineis griseis prope suturam notata ; 

 spira brevissima, ; anfractibus paucis callosis, balteo lato 

 subcarinato; columella valide callosa, plicis anticis perobliquia 

 callosis ; apertura lata ; labio tenuiusculo, medio sinuato. — 

 The most conelike of all the species. Its affinity with O. 

 gibbosa of Born is very close. 



117. ovata (f. 281, 282), Marrat.— Quam 0. Braziliana 

 magis ovata ; columella postice valde callosa ; callo antico 

 angusto, plicis tribus magnis quarum media oblique striata, 

 armato. — A more ovate shell than 0. Braziliana, with the 

 middle one of the three anterior folds striated or divided 

 into lesser plaits. This is not clearly shown in the figure. 



118. vescica (f. 280), Gmel. — Late ovata, patula, griseo- 

 fulva,. castanea, bifasciata ; spira, brevissima, calloso-tuber- 

 culata, balteo latissimo subcarinato ; columella crassa, 

 calloso-tuberculata, plicis calli antici duabus tortuosis, 

 postica duplicata; labio dilatato, sinuoso, intus castaneo 

 marginato. — Included in Lamarck's 0. auricularia, of which 

 it may possibly be a very exaggerated form. 



119. auricularia (f. 283, 284, 285).— Ovato-patula, pallide 

 grisea, castaneo lineata aut griseo punctata ; spira callosa, 

 apiculata; balteo lato, subcarinato, aurantio-fulvo, fusco- 

 purpureo nebulato, lineis impressis spiralibus tenuiter 

 striato ; columella callosa, plicis calli antici duabus, postica 

 divisa ; apertura dilatata, intus castanea, antice latissima ; 

 labio sinuato, tenui, margine pallido. 



120. cincta (f. 286, 287), Reeve. — Subovata, patula, 

 postice attenuata, pallide fulva, medio fascia fusca cincta, 

 ad suturam fusco fasciatim maculata ; spira obtuse conica, 

 balteo lineato ; columella arcuata, lasvigata, plicis calli antici 

 duabus, postica striata ; apertura postice contracts, antice 

 expansa, intus pallide fulva, castaneo bifasciata ; labio tenui, 

 arcuato, intus punctato. The figure is copied from that in 

 Reeve. The species is closely allied to 0. auricularia. 



121. biplicata (f. 288, 289, 290), Scwb.— Ovato-fusiformis, 

 pallide grisescens, longitudinaliter fusco lineata ; spira, 

 conica, acuminata, balteo angusto subcarinato violaceo ; 

 columella callosa, antice in plicis duabus tortuosis violaceis 

 terminanti ; apertura pyriformi, pallide violacea. — The speci-
