292 SPECIES OF THE SYSTEMA. 
consideration. Gualtier’s figure H represents the Columbella 
rustica of authors, which perfectly answers to the description 
and Mediterranean habitat: his figure G, if not a variety, I 
cannot recognise (C. festiva ??); assuredly nothing can be found 
in the Linnean cabinet, which contains numerous individuals of 
C. rustica (Sow. Thes. Conch. vol.i. pl. 36, f. 19, 22), that bears 
more resemblance to it. Since, then, the presence of this 
species in the collection is asserted in the lists, there can be 
no reasonable doubt of the correctness of the traditional identi- 
fication. In the revised copy of the ‘ Systema’ a reference has 
been added to “ List. 824, f. 44,’ where a Columbella from the 
Mediterranean, having much the aspect of this species, is 
delineated. 
Voluta paupercula. 
In the tenth edition of the ‘ Systema’ this well-known species 
was pictorially defined by the solely-cited figure of Gualtier, 
which represents the Mitra paupercula of authors (Knorr, Dél. 
Yeux, pt. 4, pl. 26; f. 5), and by a description which was not 
discordant with that delineation. The reference to Bonanni in 
the twelfth edition was an error (probably a misprint); his 
engraving does not exhibit the required painting, “ lineis albis 
longitudinalibus,” and was again quoted for the next species. 
Voluta mendicarta, 
Born has recognised the Linnean species in the shell (Kiener, 
Coq. Viv. Col. pl. 6, f. 1) subsequently termed Columbella men- 
dicaria by Lamarck. This identification has become traditional, 
and is by no means unreasonable, although not one of the cited 
engravings can be pronounced an indisputable likeness of it. 
All three represent a small dark and white-banded shell, that 
consequently exhibits the general aspect of Coluwmbella mendi- 
caria: all three, however, appear to differ. Petiver’s figure, 
though rude, is very like it; Gualtier’s seems meant for a very 
closely allied species (zonalis?), yet, corrected by “ ovata,” would
