234 SPECIES OF THE SYSTEMA. 
Of Seba’s drawings in his plate 49, the 76 has been referred 
by Lamarck to capitellum, but is described, in the text, as 
variegated. Regenfuss’ painting, although, like the rest, it pre- 
sents a general resemblance to the Turbinella cornigera—of 
which a specimen (Reeve, Conch. Icon. vol. iv. Turb. pL. 8, f. 40) 
is still preserved in the Linnean cabinet—was really intended 
for Purpura hyppocastanum. As some doubt may exist about 
the correctness of the term “ quadriplicata” (though Lamarck 
also has attributed only four folds to its columella), it is worth 
mentioning, that the number of the plaits was not originally 
thus limited by our author. 
The white variety with a produced spire, spoken of in the 
‘Museum Ulrice,’ was of course a distinct species. 
Voluta captteun, 
This species was pictorially defined in the tenth edition of 
the ‘Systema,’ where it appeared as a Murex, by a reference to 
Argenville’s figure of the Turbinella capitellum (Reeve, Conch. 
Syst. pl. 229, f. 5) and by a brief description that harmonised 
with it. An example of that shell is still preserved in the 
Linnean cabinet, and a rude delineation of it in Gualtier (at 
least it has been generally cited for it) is doubtfully (“t. 39, 
f. A?”) quoted, as illustrative, in the revised copy of the 
‘Systema.’ 
Among the details particularised in the ‘Museum Ulrice’ 
the passage ‘“‘ columella rugis 4 transyersis” appeared, and that 
number of plaits was likewise attributed to the Volute in the 
twelfth edition of the ‘Systema.’ Now as there happen to be 
only three folds upon the pillar of Turbinella capitellum, we 
cannot safely refer to the two later publications of Linneus in 
a correct synonymy of the species. 
Voluta Ceranitea. 
The details and the synonymy in the ‘Museum Ulrice’ 
clearly defined the object intended, which naturalists deter-
