One example in live condition, but hardly adult, and which is in shattered condition, 

 with the larger portion of the body-whorl missing, the body protruding. The comparison, 

 however, of the portion remaining with the figure in " Challenger" Report seems to 

 indicate similarity as regards size. The whole substance of the shell is of papyraceous 

 fragility.
