220 SPECIES OF THE SYSTEMA. 
(the elevation of the spire is merely in comparison with that of 
B. physis and the adjacent species). Livida, longitudinaliter 
griseo undulata,” all which, unfortunately, might quite as well 
apply to half a score at least of other shells, since even the 
modern genus is left undefined by the presence of the additional 
synonym of Lister. The colouring, moreover, if interpreted 
strictly, would be peculiarly unsatisfactory. The V. pallida of 
Karsten (‘“‘lineis flavescentibus longitudinaliter lineata”) was 
assuredly not the Linnean species, but, if a Marginella, was 
probably limbata. 
Voluta faba. 
The figure of Gualtier represents the Marginella faba of 
modern writers, and, being in accordance with the brief descrip- 
tion, pictorially defines the species. That shell (Swains. Zool. 
Illus. ser. 1, pl. 97) is still preserved in the Linnean cabinet, 
and alone of its contents agrees with the definition. 
Voluta glabella, 
This species, also, was pictorially defined in the tenth edition 
of the ‘Systema,’ by the agreement of the diagnosis with the 
only figure there cited as illustrative. That engraving (Gualtier, 
pl. 28, f. L), though somewhat rude, was clearly intended, as we 
learn from the accompanying description, for the Marginella 
glabella of authors (Sowerby, Thesaur. Conch. vol. i. pl. 72, 
f. 52, 53), which shell was likewise represented, and charac- 
teristically too, in the quoted drawing of Adanson. The details. 
of the ‘Museum Ulrice’ accord, likewise, with the features of 
that shell; yet from their paucity might suit more than one 
species. ‘The two other plates referred to (only appended in 
the twelfth edition) are wrongly indicated, though Klein’s 
wretched copy from Lister, plate 818, f. 32, has been also quoted 
by Lamarck for the Marg. glabella. In the revised copy of the 
‘Systema’ “ List. t. 818, f. 31” has been added: now the figure 
in plate 818, with the numerals 31 below it, was probably meant
