with a label on it, and as such was published in the Index 

 Testaceologicus. Gray, as I have shown, described this shell in 

 1827, and had it in tlie British Museum, and now we have a 

 record that he gave it to Hanley to figure, no doubt for the first 

 time ; to make it certain that this was the shell described by 

 Gray in King's voyage, Hanley gives a reference to King's 

 voyage which I have already given as where Gray described it. 

 Moreover he gives as the habitat "S. Seas," putting it in brackets 

 to show that Gray gave him that habitat. Deshayes, Romer, 

 and others, refer to this shell as being recorded in the Catlow 

 Catalogue No. 55, on p. 38, 1845. Another reference to it 

 will be found in Hanley's Illustrated and Descriptive Catalogue 

 of recent (bivalve) Shells, letterpress Part I., page 106, the date 

 of which is 1843. I have not got this part, and cannot con- 

 sequently give a quotation from it. 



Deshayes, in his Catalogue of Bivalves in the British Museum, 

 quoted, gives a reference to Cytherea Kingii (ex parte) in Sowb. 

 ■Thes. Conch., Vol. ii., p. 638, pi. 133, tig. 129; and Romer 

 in his Mon. Genus Veneracea, Venus, sub-genus Cytherea p. 96, 

 gives as a reference to this species Sowb. Thes. Conch., Vol. ii., 

 p. 638, pi. 133, fig. 130. (Synon. part enclus). The date of 

 Vol. II. is 1855. 



Sowerby, in the Thesaurus Conchyliorum, Vol. ll., p. 638, Sp. 

 92, 1855, descrilies Cyllierea Kingii, Gray, giving Woods' Index 

 Test. Supp. by Hanley as where the species is described, quite 

 ignoring Gray's description of it in the Appendix to King's survey 

 of the coast of Australia during 1818 and 1822, although Hanley 

 refers to it. Moreover he does not notice Hanley's " S. Seas " 

 habitat, but gives St. Thomas, West Indies, and Nicobar Islands 

 as its habitat. 



He describes the species thus : — " Smooth in the middle, shell 

 oval, oblong, not very ventricose, slightly striated at the sides ; 

 whitish, generally with chestnut rays, either linear or broad ; 

 anterior side short, sloped, with the lunule long and defined ; 

 hinder side elongated, rather square, with the dorsal edge rather 

 elevated. ' Compare this description with the one given by Gray 

 in Appendix to King's voyage, and compare also Sowerby's figure 

 with Hanley's figure in Woods' Index Test. Having done so 

 myself carefully, I feel sure that Sowerby has taken his descrip- 

 tion from the shell named Lamarckii by Gray in the Analyst of 

 1838, Vol. VIII., p. 308, which Philippi says is from Tahiti, "very 

 like this species." Sowerby, p. 639 of same vol., observes, that 

 this description will include the several varieties which have been 

 differently named, such as C. Bihmulata (no author) so labelled 

 in the British Museum, C. Lamarckii, Gray, C. Kingii, Gray 

 (C Modesla, Phil), sic.
