of about 20 0 . The specimen is broken off obliquely by the 
edge of the block of limestone in which it is imbedded ; the 
width of the gladius here (at right-angles to the mid-rib) 
being 14 mm. A prominent median keel extends throughout 
the entire length of the gladius, being fine and well-defined 
at the posterior end, becoming more elevated, broader and 
less distinctly bounded as it passes towards the anterior end. 
The surface of the posterior portion of the gladius is convex, 
becoming flatter on the anterior part, which has a rounded 
elevated ridge near each margin. Portions of the surface of 
the gladius are preserved, showing that it was of a dark brown 
colour, fairly smooth except for the rather strong and somewhat 
distant lines of growth.
