 in the middle, narrowed and sinuate in front, anterior angles pro- 

 duced, subacute ; apical margin slightly produced ; above sub- 

 convex, transversely impressed behind the middle, coarsely pimc-

 elongate ; sides parallel, narrowly margined, posterior angles armed 

 with a short flattened acute spine; apex (Tab. IX. fig. 34) rounded, 

 apical margin obtuse, indistinctly serrate ; above subconvex, flat- 

 tened along the suture ; shoulders prominent, laterally produced,
