32 SMITH : iMAKINK SHELLS FROM PORT ALl RLH. 



Marginella differens, n. sp. 



PI. ii, fig. 19. 

 Testa parva, ovata, alba, nitida : spiia brevis, ad apiccm obtusa ; anfractus 

 3I celeriter accrescentes ; latjiuni incrassatiini, intus denliculatuni ; columella 

 callo induta, quadriplicata. 



Longit. 5 millim., diam. 3.25. 



This species was quoted by Mr. Sowerby (Marine Shells S. Africa, p. 20) 

 under the name of M. IniJhom, Reeve. It is shorter than that species, has 

 coarser denticulation within the labrum, the columella callus is 11 ore defined, 

 and the second plication from the base is more produced to the left over the 

 whorl. The plicae are usually four in number, but an indication of a fifth is 

 sometimes observable. The denticles on the labrum are in the form of short 

 lirae which are vi,sible e.\teii(jrl\- through the transparency of the shell. 

 Marginella duleis, n. sp. 

 PI. ii, fig. 20. 

 Testa parva, alba, polita, subpellucida : spira brevissima alba, obtusa ; 

 anfractus 4 ; apertura angusta : labrum mediocriter incrassatum, intus laeve 

 vel liris minutis brevibus 16 — 17 denticulatum ; columella (juincjue vel 

 se.xplicata, plicis duobus anticis aliis majoribus. 



Longit. 3.5 millim., diam. 2.2. 



A very small subpellucid shell with the labrum smooth or minutely 

 denticulate or lirate within ; with a slight notch at the base or anterior end of 

 the aperture, and six columellar fijlds, of which the two anterior are larger 

 than the rest, which look more like minute denticles than plicae, and in 

 adult specimens may be more or less obscured by callus. 

 Marginella pseustes, n. sp. 

 1^1. ii, fig. 2 I. 

 Testa minuta, ovata, alba, pellucida, nitida; spira rotundata, baud exserta ; 

 anfractus 3, ultimus fere totam testam formans ; apertura angu.'^ta ; labrum 

 extus valde incrassatum, intus laeve, longit. totam testae aequans ; columella 

 triplicata, plica antica obliqua, maxima, inferne labro juncta. 



Longit. 2 millim., diam. 1.3. 



A very small species, ovate, with a rounded apex, a conspicuously 

 thickened lip for so smaM a shell, and three folds at the anterior end of the 

 columella, of which the basal one is the thickest and unites with the labrum 

 in front.

 Testa parva, ovato-turrita,palli de rufescens, supra porcas spirales rufo punctata; 

 anfractus 6, superiores duo l.ieves, convexi, mamillaeformes, caeteri supra 

 concavi, in medio nodose a igulati, liris minutis spiralibus, incrementique 

 lineis undique cancellati, ultimus porcis quaternis transversis instructus ; 

 apertura pallida, rufo fasciata, longit. totius h paulo superans ; columella alba,
