Venus puerpera, for which it must be retained. They also clear up the un- 

 appropriated residue of Venus Bolten, except V. lumens and V. dione. 



Gafrarium Bolten is by thistime relieved of the genus Corbis and retains 

 only V. reticulata L. and the Circes of the group later called Crista by Romer. 

 V. reticulata belongs to Cytherea Bolten. There is no essential change in the 

 " Animaux sans Vertebres" of Lamarck in 1818. In 1838 Gray, in the " Ana- 

 lyst," * contributes a Catalogue of Cytherea (Lamarck, not Bolten), in which he 

 proposes a genus Chione which is not Chione Megerle, but has a small anterior 

 lateral tooth and was based on Venus chione L. A genus Dosina, based on 

 Venus verrucosa L., is identical with the Cytherea of Bolten as eliminated. 



Early in the century Dr. William Elford Leach, of the British Museum, 

 was active in systematic biology and coined a large number of generic names 

 which appeared on labels of the Museum and were used in his correspondence 

 and quoted in synonymy by Lamarck, Risso, Brown, Gray, and other pupils or 

 contemporaries. These names were frequently changed by him, many of them 

 were never properly described, and even after his death Dr. Gray published a 

 work of Leach which, without adding much to knowledge or exhibiting any 

 very marked dependence on the anatomical characters of the Mollusks for 

 guidance, increased very largely the number of synonyms and uncertain desig- 

 nations of the British Mollusca. A number of names were proposed by Captain 

 Thomas Brown in his " Illustrations of Conchology" in 1827, part of which 

 were derived from Leach, and none of which were defined. Others appear in 

 Gray's very helpful but not always reliable " List of Genera of Recent Mol- 

 lusca" in 1847, in his " List of British Animals" (Mollusca) in 1851, and in his - 

 " Arrangement of the Figures" in Mrs. Gray's " Figures of Molluscous Ani- 

 mals," vol. v., 1857. 



Among important publications for the nomenclature of the Venerida; in 

 the nineteenth century is the arrangement of Morch in the second part of his 

 " Catalogue of the Yoldi Collection," 1853, where many non-binomial names 

 of Klein and others are for the first time employed in binomial nomenclature, 

 though without definitions or citation of especial type species. About the same 

 time, in the British Museum duodecimo series of publications, Deshayes published 

 a " Catalogue of the Conchifera, Part L," including the Venerida. Though the 

 laws of nomenclature were not adhered to with any strictness, and some of the 

 names therefore cannot stand, this marked a considerable advance on previous 

 literature of the subject. In 1857 Eduard Romer printed as an inaugural dis- 



*Vol. viii., No. xxiv., pp. 302-9, London, 1838.
