This well-known species, the most abundant of the 



genus, is well distinguished by its numerous gi'ooves and 



siria?, and by its prominent sharp nodules.

Slruthiolaria gigas, Sowerby. 

 Strutldolaria papulosa, Deshayes. 

 Ilab. New Zealand. 



This fine species diifers principally from the more 

 common S. papulosa, in being less sharply angled, and 

 in the nodides being smaller and more distant from each 

 other, in the sutures being slightly channelled, in the 

 striae being alternately larger and smaller, and in the very 

 solid thickening of the lip.
