along the margins, and covered with large, prominent tuber- 

 cles. Infrabasals five, forming a rather small, flattened pentag- 

 onal disc, of which about one-third is hidden by the column. 

 Basals large, strongly curved, about as high as wide. Eadials 

 twice as wide as high, about the size of the basals ; articulating 

 surface broad, flat. First anal plate quadrangular, about one- 

 half the size of the basals upon which it rests ; second anal 

 plate not quite so large, and resting upon the first anal piece 

 and one of the basals and between the two radials ; it is pen- 

 tagonal in shape. Surface ornamented by numerous large 

 nodose elevations and microscopic granulations.

This form is more closely related to E. verrucosus than to 

 any other species, from which it differs chiefly in having more 

 intricate sculpturing, and in the smaller and concave infrabasal 

 circlet of plates.
