Passing over for the moment the effect of this state of affairs on 

 nomenclature, \ve may note the subsequent contributions of authors 

 to the literature of the subject, previous to the publication of the 

 MoUusks of Lamarck's " Animaux sans Vertebras," 1818-1822. 



Linne had named a Rostellaria '' Stnvnbus fusus." It was not sur- 

 prising, therefore, that this shell should be regarded by collectors as 

 the typical spindle shell, nor that the author of the anonymous 

 "Museum Calonnianum " (1797) should have reserved the name 

 Fusus for two varieties of this Linnean shell and for them alone. . 

 In the same work the genus Fusus is preceded by a genus Colus, con- 

 taining only one identifiable species, Murex colus Linn^, and this 

 follows a genus Turris. Under l^urris all the species are nude 

 names, but one of them, T. bahylo)iica, has been identified tradition- 

 ally with the Turris bzbylonica of Rumphius and Miiller's " Knorr," 

 a shell which later became the type of Lamarck's genus Pleurotoina. 



In 1789, in the " Encyclopedie Methodique," p. 15, in the "Tab- 

 leau Systt^matique des Vers," Bruguiere has the following entry: — 



" Genre 45. Fuseau. Fusus. Coquille fitsifonne sans varices, 

 terniin'ee a la base par un canal eh^&it^ droit, 6u rec&urbS. ' ' A9(Jt-cXj» XA/l^^l, i 



No type or species is mentioned, and it is obvious that the name 

 might be applied on the basis of the diagnosis to any fusiform, non- 

 varicose, canaliferous gastropod. No further data were furnished 

 by Bruguiere, and it was only some twenty-six years later that the 

 plates of the " Encyclopedie," containing species of Fusus, were pub- 

 lished by Lamarck, who had altered and improved the classification 

 of his predecessor, so that it cannot be recognized as Bruguiere's. 



However, in 1798, Cuvier,^ cites as examples of Bruguiere's genus 

 (which he regards as a subdivision of Murex) the Murex fusus Linne, 

 1758, and Murex colus L., which are equivalent to /Rostellaria and 

 Fusus of Lamarck's " Prodrome " of the following year. 



Of the shells which were geneially grouped about Murex colus 

 Linne, we find in 1798 a large number included by Bolten in a new 

 genus, NeptuneaP- Colus is used by him for a series which begins with 



1 " Tableau El^m," p. 403.
