358 SPECIES OF THE SYSTEMA. 
the ‘Systema.’ The Linnean shell was apparently included in 
the H. volvulus of Miiller (whose oculus-capri was avowedly not 
that of our author), evidently so in the Turbo volvulus of 
Chemnitz (f. 1066), and was one, if not the principal, of the 
Cyclostome confounded by Lamarck under the same specific 
designation. 
Belix albella. 
Several examples of the Carocolla albella of Lamarck (H. ex- 
planata, Rossm. Iconog. pl. 39, f. 539) were found in the cabinet 
of Linneus, wrapped up in a morsel of Swedish paper. As these 
specimens admirably and exclusively agree with the diagnosis 
of this species, whose presence in his collection has been re- 
corded by our author, no doubt of their typical authority can be 
reasonably entertained. In the revised copy of the ‘Systema’ 
“ List. 80” has been referred to; which figure, whether intended 
or not for that species (it has been cited as a variety of it by 
Dillwyn), greatly resembles the more rubbed and aged indi- 
viduals of the collection. The younger Linné has quoted in 
preference “ List. t. 64, f. 62,” which is a far more accurate 
representation of the species in question. From the circum- 
stance that this Helix was inserted in the list of Northern 
Testacea in the ‘Fauna Suecica, whereas the Lamarckian 
albella is a native of the sunny South, and that the cited figure ~ 
of Gualtier bears much resemblance to the H. radiata, Nilsson 
has suggested that the young of that well-known snail was 
possibly intended by this appellation. The “supra planiuscula, 
marginata” (Act. Upsal. 1736) and the “subtus valde gibba” 
(F.S.) are not suitable for that shell, of which, moreover, no 
individuals are to be found in the Linnean collection. So large 
a proportion of our supposed native T'estacea has been admitted 
without due credentials, that it is far from improbable that one 
or two exotic species may have been introduced into the Fauna 
of Sweden.
