Monograph on the Ct/ptveideie, by Mr. Gray. 79 



I am not certain that my shell is the same as Lamarck describes, 

 though it agrees with all his characters, for my own has certainly 

 more affinity to C. Mauritiana than C. arabica. Lamarck observes 

 that the dorsal line is rather branched; in my specimen, which is 

 perhaps not quite so full grown, I cannot observe any. It is in- 

 stantly to be distinguished from all the other Cypraeae by its promi- 

 nent spire, flat base, and very deep groves between the hinder teeth.
