The doubtful Volute. Shell ovately fusiform, spire 

 papillary towai-ds the apex, whorls transversely very 

 finely striated, longitudinally slightly plicated, eolii- 

 mella scarcely plaited; yellowish, tessellated with 

 rows of square fulvous-red spots.

The columeUar plaits of this species, which is unknown 

 to me, are so faintly developed, that some doubt has been 

 entertained of its genus. Shortly after the publication of 

 it as a Vohde in the Zoological Journal, from a specimen 

 brought to this country by M. Roussel wliich Mjt. Sowerby 

 mentions having had in his possession, a second specimen 

 was figured by Schubert and Wagner in their Supplement 

 to the ' Conchylien Cabinet ' as a Fusiis. M. Kiener pub- 

 lished a third specimen in his monograph of the same 

 genus, in which the columeUar plaits are not indicated at 

 all. In my monograph of Fimts I introduced a copy of 

 this (Conch. Icon. Fusus. PI. XIV. Fig. 53). Mr. 

 Sowerby has, however, kindly drawn my attention to its 

 identity with the figure of FoMa dubia of the Zoolcgical 

 Joui'nal, and from the papUlary structure of the apex there 

 can be little doubt that the true position of this very rare 

 and interesting species is in the genus to which Mr. Bro- 

 derip fii-st assigned it.

The concentric ribs of this little species range some- 

 what obliquely, the interstices being finely latticed with 

 small ridges.
