Bemarks. — This characteristically southern form is included in our lists of 

 British shells on the strength of a few specimens found in Jersey and off the 

 northern coast of Devonshire. As a British fossil it has been reported only from 

 Selsey, the molluscan fauna of which, as pointed out by Wood and A. Bell,^ has 

 a strongly marked Lusitanian and Mediterranean character — a fact which deserves 

 more general recognition than it has hitherto received. 



The subgenus Massotia was |)roposed in 1884 by Messrs. Dautzenberg and 

 Dollfus for a group of Bissose. having an oval form, a short spire, the last whorl 

 being tumid and the sculpture feebly reticulate. This subgeneric name has been 

 adopted by several subsequent Avriters.
