366 SPECIES OF THE SYSTEMA. 
Helix Gothtea. 
Although declared to be a native of Sweden, no mention of 
this shell occurs in the ‘Fauna Suecica.’ It could not be 
hoped that any naturalist would succeed in identifying a 
species defined solely by four characters, and unillustrated by 
any synonymy. The young of H. lapicida has been suggested 
as fulfilling most nearly the required conditions of features and 
locality; but certainty upon this point can never be attained | 
to, as the description was not drawn up from specimens in the 
collection of our author or of his royal patroness. 
Helix Gualtievana, 
This is indisputably the Carocolla Gualteriana of Lamarck 
(Born, Mus. Ces. pl. 18, f. 12, 13), the characteristic drawing of 
the author, in honour of whom it was designated, having always 
prevented any doubts upon its identity. By a typographical 
error, the correct reference to Gualtier, “68, f. E” has been 
changed to “69, f. EK” in the Vienna reprint of the twelfth 
edition: the latter figure represents an Haliotis. Linneus did 
not possess this shell. 
Helix corned, 
No shell in the Linnean collection will agree with the descrip- 
tion and the synonymy of this species (for there are no allied 
congeners present), except the Planorbis whose identity has 
been universally allowed, the P. corneus of Draparnaud (Moll. 
Ter. et Fluv. France, pl. 1, f. 42, 438, 44). Our author has 
written, in one of his many copies of the ‘Systema,’ “ ex hac 
fecit Lister purpuram, pungendo inter tentacula.”
