272 Mr. L. Reeve on the Synonymy of 



of Linnseus to put numbers on his specimens in ink^ cor- 

 responding with numbers written by him in ink against the 

 descriptions in his private copy of the ' Systema Naturae/ The 

 original type of Linnseus^s Voluta cymhium is in the possession 

 of the Linnsean Society, and I find it upon examination to be 

 a young Cyrnbium porcinum, or proboscida/e^ which are probably 

 one and the same species. The number on this specimen agrees 

 with the number in Linnseus^s private copy of the ' Systema.' 

 Linnseus's synonymy was, however, very confusing on this point. 

 The shell of C. cisiwn was not known to him, and he referred to 

 a figure of it in Gualtieri (Test. pi. 29. f. B) in illustration of 

 his Voluta cyrnbium. On looking to this figure in Linnseus's 

 own copy of Gualtieri, I find the name V. cymbium in the 

 margin in Linnseus's handwriting; but he appears subsequently 

 to have discovered his error, for in his latest synonymy of the 

 species in the ' Museum Ulricse ' the reference to this figure is 

 suppressed. 



6. Cymbium {Yetus) patulum, Broderip, Spec. Conch, f . 4, 4 6 ; 

 Conch. Icon. pi. 25. f. 16 a, b. 



Cymhium Neptuni (young). Gray. 

 Hab. West Africa. 



Is this the young of C. Neptuni, or a distinct species ? It is 

 not uncommon. There are several specimens in the British 

 Museum, and Dr. Gray fancies that they show a passage of 

 growth into C. Neptuni. The evidence of their relationship is 

 by no means complete, and the columella of C. patulum is only 

 two-plaited. 



7. Cymbium {Yetus) rubiginosum, Swainson, Exotic Conch, pi. 28; 

 Conch. Icon. pi. 26. f. 18 a, b. 



Voluta rubiginosa, Swainson. 

 Le Philin, Adanson. 

 Cymba rubiginosa, Broderip. 

 Yetus cymbium (pars), Gray. 



Hab. North-west Africa. 



The Rev. R. T. Lowe has given a full and most interesting 

 account of this species in the notes to his " List of Shells ob- 

 served or collected at Mogador during a few days' visit in April 

 1859" (Proc. Linn. Soc. 1860, p. 169). He considers C. rubi- 

 ginosum, and not C. porcinum or p?'oboscidale, as quoted by Dr. 

 Gray, to be Le Philin of Adanson. Dr. Gray gives C. rubi- 

 ginosum as a synonym of his Yetus cymbium, which is not the 

 Jjinnsean Voluta cymbium, but C. cisiuin, Menke. Mr. Lowe 

 collected two well-defined varieties of C. rubiginosum, which he
