4, ultimo elongato-ovato ; sutura vitrea : apertura antrorsum dila- 

 tata ; labro tenui, inflecto, postice callo modico suffulto ; columella 

 4-plicata. Axis 12; diam. G millim. Inhabits Simon's Bay, in 

 18 fathoms, gravelly bottom. W. S. 



Resembles V. zonata, but is much larger; possibly the shell 

 given by Sowerby as a variety, though no traces of bands are 

 visible. Like V. tceniata in form and size, but with a different 

 lip. The animal is very active, of a pale lemon-color, with 

 blotches of flake-white and very numerous crimson points ; mar- 

 gin of mantle dark chocolate. Generally like the animal of Pcr- 

 sicula.

 dula, lineis incrementi et postice striis volventibus insculpta : 

 apertura linearis ; labro angusto vix crenulato, porcellano, utroque 

 pariter producto, postice canalem contortam obliquam callo cir- 

 cumdatam effbrmante, antice una cum plica columellari canalem 

 brevem angustam definiente. 



Closely resembles A. umbilicatus and margarita, but wants the 

 perforation and triply dentate callus of the former, and is much 

 less acuminated, with a less distinct canal and a denser and more 

 crenulated lip, than the latter.

 do-lutescens, apice, linea subsuturali, et lineis alteris minoribus

Allied to P. succincta. 



Planaxis cingulata. T. parva, crassa, ovato-turrita, glabra, 

 fusco-rufa flavido alternatim zonata, stria intercurrente ; anfr. 

 7 convexiusculis, apicalibus granulosis, ultimo magno: apertura 

 anguste ovata ; labro obliquo intus 7 denticulato et fasciato ; colu- 

 mella excavata, rufa. Axis 12 ; diam. 6 millim. Inhabits Ou-
