VOLUTA. 233 
The Voluta vespertilio (Martini, Conch. Cab. f. 938) is still 
preserved in the Linnean cabinet, and exclusively agrees with 
the definition of the species. 
Voluta Lbrxa. 
The majority of the references attached to this species should 
rather have been quoted for the preceding; some of them, in- 
deed (Gualt. pl. 28, f. G, and Seba, pl. 57, f. 5) have actually 
been included in the synonymy of both. The referred-to 
drawings in the sixty-fourth plate of Seba’s folio represent the 
Voluta scapha, but as the number of the columellar folds in both 
it and vespertilio is far less than is required by the diagnosis, 
naturalists have properly rejected these engravings as illustra- 
tive, and preferred those of Argenville, Bonanni and Seba, 
pl. 57, f. 1, 2, 8, 6, since they represent a shell, the Voluta 
Hebrea of authors (Knorr, Délices Yeux, pt. 6, pl. 15, f. 1), 
whose characters are in harmony with the specified features ; 
their selection is corroborated by the additional reference of 
“List. 809” in the revised copy of the ‘Systema.’ No speci- 
men of it, however, is preserved in the Linnean cabinet; the 
depth of the drawers would not have permitted its insertion. 
Voluta turbinellus, 
The correct determination of V. Ceramica, which is stated to 
resemble an elongated turbinellus, would naturally suggest the 
Turbinella cornigera, from the great similarity of the two allied 
congeners, as the representative of the present species. The 
selection, in the ‘Museum Ulrice,’ of the figures in Gualtier, 
Argenyille and Rumphius, which clearly were designed for that 
shell, adds strength to the recognition, since these are the only 
ones of those cited in the ‘Systema’ which indisputably repre- 
sent it, though Seba’s figure 8 and the wretched engraving of 
Bonanni have, also, been ascribed, and bear a certain degree of 
likeness to the same object.
