Though the species is rather variable in colour and even slightly in sculpture, none of 

 the specimens agrees sufficiently with P. gemmata Hinds, as described and figured by Reeve, 

 the whorls being by no means so strongly concave between two keels, so I have followed Smith (1. c.) 

 in naming them P. fusca-^ the specimen from Stat. 156 is very doubtful, being a worn shell, 

 which agrees however in shape with typical P. fusca, as figured by Tryon. Mr. Smith, whom 

 I wrote about the question, persists in his opinion, that the two forms are separable and that 

 the true gemmata is Californian. May it be that P . gemmata of many authors is not the same 

 as that of Hinds? Some very young specimens are of course rather doubtful.
