422 SPECIES OF THE SYSTEMA. 
It is much to be regretted that Linnzeus did not himself possess 
the species. 
Watella Clngarica, 
The Pileopsis Hungarica of modern writers (Sowerby, Genera 
Shells, Pil.) is marked for this species in the Linnean cabinet. 
In the revised copy of the ‘ Systema’ ‘‘ Mart. Syst. t. 12, f. 107, 
108” has been added to the references, and “hee habet 
epidermidem” appended to the description. The published 
synonymy, although it served, when combined with and modi- 
fied by the description, to indicate the species actually in- 
tended, was, nevertheless, somewhat faulty. For Klein’s 
cited drawing, which, from its rudeness, might pass equally 
well for P. Hungarica, was copied from Lister’s represen- 
tation (Hist. Conch. pl. 544, f. 32) of P. intorta; and Ginanni’s 
figure, although probably designed for the shell, was very 
inaccurate. 
| Patella antiquata, 
The Pileopsis (Hipponyx) mitrula of Lamarck (Martini, Conch. 
Cab.i. pl. 12, f. 111, 112, copied from Lister) is marked for this 
species in the Linnean cabinet, and perfectly agrees with its 
description. It was recognised for the P. antiquata by both 
Montagu and Dillwyn, although its diagnosis was not illustrated 
by any pictorial synonym, an omission rectified in our author’s 
copy of his ‘Systema’ by the citation of “ List. t. 544, f. 31.” 
The locality “ Barbadoes” is correctly stated in the manuscript 
of the younger Linné. 
Patella mranuniillaris. 
As our author has recorded his possession of this limpet, 
and one shell alone of the entire Linnean collection adequately 
agrees with the description of it, that example is manifestly 
entitled to be considered the typical mammuillaris. It was
