SHAW : ON CTPRJEA AND TRIVIA.

monograph ' on Cyprcea, which certainly of its kind is the best 

 published, and to him all those who specialize in the genus are 

 greatly indebted for the trouble and care he has taken in its prepara- 

 tion, and for his exhaustive synonymy. The reasons for differing 

 from his views in certain cases and the conclusions arrived at will 

 appear later on. 



While writing this paper Mr. C. D. Sherborn conclusively proved 

 to me that the "Descriptive Catalogue of Shells by John Edward 

 Gray," 1832, was never published, but existed only in a few proof- 

 sheets. It must therefore be regarded in the same light as manuscript 

 and no longer quoted as a publication. The species described in it 

 for the first time must therefore take as their author the next writer 

 who adopted them. 



It is most probable, indeed almost certain, that this Catalogue has 

 never been seen except by the officers of the Natural History Museum, 

 where the extant proofs are preserved, and perhaps by one or two who, 

 like myself, have been working there. The reason that it has always 

 been quoted in the various monographs on Cyji^r^ea, by Eeeve, Sowerby, 

 Weinkauff, lloberts, Ivicner, Melvill, Hidalgo, etc., is that Sowerby 

 refers to it in his " Conohological Illustrations" (Gray having probably 

 given him a copy), where he quotes the species with Gray as the 

 author and gives references to the Catalogue, which evidently 

 have merely been copied by later writers. 



I now give a list of the species of recent Cyprcea and Trivia described 

 by Gray in this Catalogue, quoting the writer who first adopted them, 

 who, as stated above, must be regarded as the author. The place 

 where this author first mentions them should also be considered the 

 place of publication. Where referred to in this paper, I have quoted 

 the proper author, entirely eliminating the "Descriptive Catalogue."
