344 SPECIES OF THE SYSTEMA. 
Turbo reflexts. 
Dillwyn, in his excellent ‘Descriptive Catalogue,’ has sug- 
gested that this doubtful species might prove identical with the 
well-known Cyclostoma elegans, a species so remarkably abun- 
dant, and so widely diffused, as to appear very unlikely to have 
eluded the observation of Linneus. This conjecture, for the 
meagre and unillustrated description of the ‘Systema’ per- 
mitted no logical demonstration (hence the more ancient name 
cannot obtain precedence), is corroborated by the contents 
(C. elegans, Sow. Thes. Conch. Cyclost. f. 32, 33) of the marked 
receptacle of Turbo reflexus in the Linnean cabinet. 
Curdo Htretwa. 
Our author did not possess this shell. All the four cited 
cited figures have been ascribed to the same Cyclostoma, which 
has been justly selected by Sowerby, in his late Monograph of 
that genus, as the representative of the Linnean species (Thes. 
Conch. i. pl. 28, f. 148, 149). Browne’s engraving, indeed, is a 
characteristic one, and harmonises with the description in the 
‘Systema ;’ Sloane’s, on the contrary, requires the aid of the 
accompanying text to be rightly understood. 
Turbo twbrteatus. 
The specimen of this shell, marked as such by the author of 
the ‘Systema,’ correctly agrees with the peculiar character 
assigned to the species in the ‘Museum Ulrice,’ “ anfractus 
inferiore latere gibbosiores, inde quasi extra superliorem im- 
bricati.” Its presence in the Linnean cabinet is of importance, 
since, as M. Deshayes justly observes, even the enlarged descrip- 
tion in the ‘Museum Ulrice’ is not sufficient to enable us to 
determine its identity with any known species. The only per- 
manent reference to a figure was to Gualtier, plate 58, £; which,
