The following teeth appear to belong to the same species as the 
tooth from the Stonesfield Slate figured by Phillips ( op.cit .), without 
description, under the name of Strophodus lingualis. They are of 
very small size, the principal teeth narrow and not measuring more 
than 0-018 in length ; the coronal surface is very coarsely reti¬ 
culated, the transverse markings being especially prominent; and 
there is occasionally a longitudinal ridge.
