PLATE XLIV, FIGURE 18. 
Shell rather large, thick, and strong, moderately stout, gradually 
tapered, gently curved, chiefly behind the middle. The sculpture 
consists of about eleven strong, prominent, broad, obtuse, longitudinal 
ribs, separated by deep, concave interspaces, which are wider than 
the ribs in the middle of the shell and of about the same breadth pos- 
teriorly ; at about the anterior third the ribs decrease in prominence, 
fading out, or becoming flattened into mere obtuse angles at the an- 
terior end; along the middle of the shell a smaller rib intervenes 
between part of the larger ones; four of the ribs on the convex side 
are closer together and narrower than the rest, while those on the
