Over 100 very fine live shells, which I have separated into no less 

 than 15 well-marked color varieties. They vary from very light 

 cream-color, body sparsely blotched with brownish-black spots, to 

 others which are deeply mottled like tortoise shell. 



There are also a number of immature shells of various sizes* 

 These specimens are incomparably finer in polish and lustre than 

 specimens of this species usually imported in bulk, and which are 

 much scratched and without lustre. 



Native name, Hibi-bora ; Japanese name, Neko-gai (or cat shell).
