THE cHaRIoT CymBium. Shell somewhat squarely ob- 
long, fulvous or glaucous, wave-streaked and broadly 
banded in a clouded manner with purple-chestnut, 
spire very short, somewhat immersed, whorls flatly 
convex, rudely sharply produced round the upper 
part, rather narrowly and deeply channelied around 
the spire; columella three-plaited, richly stained with 
scorched chestnut.

It is to be regretted that Mr. Broderip, Mr. Adams, and 
Dr. Gray have followed Lamarck in assigning Linneus’s 
Voluta cymbium to this species, notwithstanding the con- 
vincing testimony to the contrary given by Deshayes in a 
note to the species in his edition of the ‘Animaux sans 
Vertébres.’ It was the practice of Linnzus to attach 
numbers on specimens in ink, corresponding with numbers 
written by him in ink against the descriptions in his pri- 
vate copy of the ‘Systema Nature.’ The original type of 
Linneus’s /”. cymbium is in the possession of our Linnean 
Society, and I find it, upon examination, to be a young 
Cymbium poreinum, or proboscidale, which are probably one 
and the same species. The number on this specimen 
agrees with the number in Linneus’s private copy of the 
‘Systema.’ Linnzeus’s synonymy was, however, very con- 
fusing on this point. The shell of C. cisiwm was not known 
to him, and he referred to a figure of it in Gualtieri 
(Test. pl. 29. f. B) in illustration of his Voluta cymbium. 
On looking to this figure in Linneus’s own copy of Gual- 
tieri, I find the name /. cyméiwa in the margin in Lin- 
neus’s handwriting ; but he appears, subsequently, to have 
discovered his error, for in his latest synonymy. of the 
species in the ‘Museum Ulrice’ the reference to this 
figure is suppressed.
