The following species originally described as a variety seems from 

 additional material to be distinct. 



LATIRUS MULTILINEATUS Dall. 



Latirus floridanus var. multilineatus Dall, Trans. Wagner Inst., vol. 3, 

 pt. 1, p. 107, 1890.

 7 (only), 1890. 



Tampa silex beds at Ballast Point, Tampa Bay, Florida; Burns 

 and Dall. U. S. Nat. Mus. No. 112123. 



By an error in numbering figure 6 of plate 8 in the original publi- 

 cation was referred to this species, but it really belongs to another 

 shell.

A single specimen was collected by the writer. It differs by its 

 shorter canal and the number of its axial ribs from L. multilineatus. 



Genus FUSINUS Raflnesque. 



Fusinus Rafinesque, Anal, de la Nature, p. 145, 1815. New name for 

 Fusus Lamarck, not Helbling. 



Fusus BbuguiI:be, Encycl. Meth., p. 15, 1789; nude name. Lamarck, Pro- 

 drome, p. 73, 199. Sole example, Murew coins Linnaeus. Not Fusus 

 Helbling, 1779. 



Fusinus Dall, U. S. Geol. Survey Prof. Paper 59, p. 36, 1909. 



I have shown in the above-cited paper and in the Journal of 

 Conchology (Leeds) for April, 1890, p. 289, that the familiar name 

 Fusus having been first binomially used for a group of species en- 

 tirely distinct from that of Lamarck can not be used for the latter, 

 and therefore it is necessary to take the first available substitute n3 

 the name of the latter.
