' Suter thinks this is a variety of menziezi, but Colenso states that the posterior 

 slope is keeled. If this is so, it must be quite different from that species. 



"Lamarck's description of this species is wholly inadequate, and would apply about 

 equally well to several species. He refers to no figure, and Lea states that he did 

 not see the type. I credit the species to Hanley, whose figure seems to represent a 

 form of an abundant and variable species commonly referred to Lamarck.
