OLIVA. 41 



Found among specimens of 0. pwrvula, and at first thought 

 to be a variety of that common species, but the form and 

 characters of the columella were found so to differ that the 

 first opinion could no longer be held. 



218 (or 162a). pulicaijia (f. 464), Marrat. — Elongato-fusi- 

 formis, pallide fulva, infra suturam et supra balteum fasciatim 

 fusco-punctata, inter fascias lineis longitudinalibus pallidis 

 angulatim undatis notata ; spira, conica, producta, apice 

 acuto, anfractibus planulatis; columella arcuata, dense elon- 

 gato-plicata, plicis calli autici tribus subvalidis ; apertura 

 intus pallide rosea ; labio tenuiusculo, antice subexpanso. — 

 Nearest allied to 0. gracilis, but the plaits #re very much 

 finer, and the close spotting is peculiar; the form is also 

 different. 



219 (or 171a). plana (f. 463), Marrat. — Oblongo-ovata, 

 inflata, pellucida, alba, nitens, ad suturam opaca, obsoletis- 

 sime fusco punctata ; spira late et breviter conica, anfracti- 

 bus subrotundatis, sutura, canaliculata ; columella arcuata, 

 callosa, plicis numerosis striata, antice ad terminum trun- 

 cata ; apeitfura intus alba, labio acuto. — This small shell re- 

 sembles 0. buttula, Reeve, in form, but the plaited columella 

 will serve to distinguish it. 



220 [or 186a). capensis (f. 469), Sowerby. — Elongato-sub- 

 fusiformis, tenuiuscula, griseo-purpurea, strigis pallidis un- 

 dulatis longitudinaliter notata, infra suturam albo fasciata, 

 rubro lineatim maculata ; spira elevata, pyramidata, apice 

 purpureo; balteo albo, antice fascia castanea lata, cincto; 

 apertura breviuscula; labio arcuato, tenui, antice subexpanso ; 

 columella, lasvigata, ; callo antico parvo, fusco, oblique bipli- 

 cato. — Perhaps nearest to 0. ojanea, but more light, thin, 

 and fusiform. The chestnut band on the belt, and the 

 double fold of the anterior callus, are striking characters. 



221 (or 77a). grata (f. 470), Marrat. — Blongato-cylindrica, 

 vix conica, flavido-fulva punctis rubro-fuscis longitudinalibus 

 transversisque, cum fasciis duabus litteratis notata ; spira, 

 late conica, anfractibus planulatis, sutura canaliculata ; colu- 

 mella, fere omnino plicata, plicis calli antici tribus aut qua- 

 tuor intersulcatis ; apertura intus alba, labio intus rubro 

 margiuato. — Having but a single specimen of this shell, I 

 cannot trace its affinities. (Mar.) Does it not resemble 

 0. Carolinianu, Duclos ? — Ed.
