whose errones, s. str. (fig. 129), belongs to another variety ; it is 

 identical with bimaculata, but has no spots on the anterior extremity, 

 and is also allied to var. chrysophcea, Melv. 



C. MONETA, Linn., var. rosea. Gray (1828). 

 Gr. 82. — A very striking variety which has never been described 

 afterwards. It is fleshy white, with two reddish purple bands. 

 It can hardly have been a decorticated shell, for Gray always 

 recognized such specimens. 



C. OBVELATA, Lam., var. vitellus, Gray (1825). 

 D. 493. — I doubt whether this fulvous variety really belonged 

 to C. obvelata, which I consider to be a subspecies of C. annulus, 

 Linn., while C. moneta is, I think, quite separable. Its margins are 

 described as somewhat depressed. I possess pinkish orange 

 specimens which are intermediate between annulus and obvelata, 

 and otherwise agree with Gray's description of his vitellus. It may 

 perhaps be allied to moneta var. aurea, Shaw (1909), which also 

 comes from the South Seas. 



C. ANNULUS, Linn., var. fossilis, Gray (1828). 

 G. 83. — It is identical with C.fabagina var. broccMi, Desh. (1844), 

 but being preoccupied by two fossil varieties of Gray (C. 371, 

 D. 496), I do not recommend the use of Deshayes' well-known name. 



C. Mus, Linn., var. tuberculata, Gray (1828). 

 G. 83. — This is the heavy shell with one or two tubercles on the 

 back, afterwards called by Sowerby (1870, Thes. Conch., Cyprcea, 

 fig. 321) var. bicornis, which name therefore becomes a synonym 

 of tuberculata. 



C. MUS, Linn., var. fossilis, Gray (1825). 

 D. 496. — This shell is identical with Lamarck's fossil C. mus, 

 I presume, as Gray cited it from " Fiorenzola in Plaisantin, 

 Lamarck " ; therefore it belongs to C. porcellus, Broc, var. 

 pseudotypica, Sacco (1894, Moll. terr. terz. Piem., xv, p. 25). 



C. ALGOENSis, Gray, var. edentula. Gray (1825). 

 D. 498. — This is the well-known shell which was believed by all 

 previous writers to have been named edentula by Sowerby (1832 

 and 1837). It is a distinct species or at least a good subspecies of 

 C. algoensis, for I do not know of any intermediate specimens 

 which might link up algoensis to edentula. On the contrary, in the 

 collection of shells brought by Dr. Penther from Port Alfred (South 

 Africa) and preserved in the Museum of Natural History in Vienna, 

 there are many hundred edentula, a few of which have slight 

 indications of teeth on the anterior part of both lips, but all are 

 quite different from the true algoensis, which is not represented 

 in this large collection from South Africa.
