The so-called species of C Hone 11a are not always easy to 

 distinguish, and beyond a difference of colour and the 

 absence of spiral striation, there is little to distinguish the 

 present new form from that which I described under the 

 name of C. Bornii^. The remains of the periostracuni in 

 C. confusa are dark or blackish brown.
