This is an interesting variety in wliieli the keel, rapidly increasing in breadth 

 over the basal c{uadrant of the shell, is deflected just before reaching the aboral 

 extremity and as rapidly decreases in breadth and vanishes, with the result that 

 the extreme aboral end of the shell shoAvs two keels somewhat widely separated. 

 The figure will explain the structure.
