228 SPECIES OF THE SYSTEMA. 
Volta sanquisuga, 
Lamarck unfortunately has accepted Seba’s figures as cha- 
racteristic of the Linnean species; but these were only added 
in the twelfth edition, and disturb the previous harmony of the 
synonymy. The engravings originally cited—Gualtier’s draw- 
ing, however, is rather uncertain—represent Mitra stigmataria 
(Reeve, Conch. Icon. vol. ii. Mit. pl. 8, f. 15), to which, alone 
of the two, the passage “‘ Fasciz anfractuum e punctis sanguineis 
distantibus” will correctly apply, and that shell is assuredly the 
rightful representative of the Linnean Volute. ‘The term 
“quadruplicata” seems opposed to the “‘triplicata” of Lamarck’s 
description; the lower or fourth fold, however, though much 
less conspicuous than the rest, is present in all my specimens, 
and the larger number has been properly assigned to it by Reeve. 
Neither M. stigmataria nor M. sanguisuga of Lamarck are to 
be found in the Linnean collection. 
Poluta Caftra. 
As the cited figure of Gualtier (misprinted 2 instead of E in 
the twelfth edition only) clearly represents the Mitra Caffra_of 
authors, a shell which precisely answers to the description in 
both the ‘Museum’ and the ‘Systema,’ that species has, with 
justice, been accepted as the representative of the Linnean 
Volute. Seba’s figures, moreover, are generally accepted as 
delineations of the same, and seem to have been drawn from 
some large polished specimens or the smoother variety. The 
Mitra Caffra (Encyclop. Méthod. Vers, pl. 378, f. 4) is still 
preserved in the cabinet of Linneus, and alone suits his defini- 
tion of the species. 
Voluta florto. 
This species appears to have been quietly passed over by 
most writers, who, if they have mentioned it at all, have merely
