292 JOURNAT. OF CONCHOI.OGY, VOL. II, NO. lO, APRIL, I906. 



Fasciolaria tuHpasindi includes Mmex islandicus Gtnelin, a Euthria (?) 

 and a Mazzalina (?). Bolten's Fusiis follows. It begins with Fascio- 

 laria trapezium and includes Latirus in the first section which has a 

 plaited pillar ; the second section with a smooth pillar is made to 

 include Murex tuba, M. ternatanus, M. morio, M. cethiops, M. vesper- 

 tilio, and M. fuarroccanus of Gmelin. The Colus group, including the 

 great Murex aruanus Gmelin, is called Syrinx (not of Bohadsch, 

 1 761)', while for the Gladius of Klein, the Fusus of the "Museum 

 Calonnianum," the name Tibia is proposed. Rumphius' Turris is 

 revived for the Pleurotoma group (the first species being Murex baby- 

 lonius Gmelin) following Miiller and the "Museum Calonnianum." 

 The following year Lamarck publislied his epoch-making "Prodrome 

 d'une Nouvelle Classification des Coquilles," in which the groups 

 above discussed were given the following names and types : — 



Rostellaria - Sirombus fusus Linnd, 



Fus2is - - Murex colus Linnd. 



Pleurotoma - Murex babylonius Linne. 



In.1801 this was followed by his " Systeme des Animaux sans 

 VtTtebres," where we find :— 



Rostellaria - R, subulata Lam. 



Fusus - - F. longicauda Lam. 



Pleurotoma - P. babylonica Lam. 



Li 1802 Bosc^ adopts Rostellaria and mentions Lamarck's other 

 genera, but in his text includes them all under Murex. Roissy, in 

 1806,^ adopts all the above-mentioned names of Lamarck with the 

 same types. Montfort, in 1810, does the same, except that he 

 modifies Rostellaria to Rostellum and Pleurotoma to Pleurotomus. 



Link, in 1807,^ adopts the Lamarckian Pleurotoma and Rostellaria, 

 but combines xhtNeptunea, Colus, and Fusus of Bolten under the first 

 name. Perry, in 18 11,* unites Fusus and Pleuroioma under the name 

 oi Murex, while retaining Rostellaria. In 18 17, Schumacher* accepts 

 Lamarck's names for the above-mentioned groups. 



This brings us to the period of the " Animaux sans Vertebres," 

 after which the influence of Lamarck prevailed to such an extent as to 

 cause a general acquiescence in his nomenclature, the changes being 

 chiefly of the nature of subdivisions, with which, on this occasion, we 

 are not concerned. 



It is evident from the foregoing : — First, that the first binomial use 

 of the generic name Fusus was by Helbling in the year 1779. Second,
