Cerithium clava, Sovverbv. 

 Hab. Philippines. 



A more solid and pyramidal shell than V. aluco. From 

 its form it was believed by the late Mr. Sowerby to repre- 

 sent the Cerithium clava, which had been previously 

 named C. maculusum. The latter shell being now iden- 

 tified, M. Kiener found it necessary to adopt the present 

 name for our shell.
