420 SPECIES OF THE SYSTEMA. 
significant numerals partially erased, is still preserved in the 
cabinet of Linneus, who has corroborated the established 
opinion by his citation of figures 71, 72 of Martini (vol. i.) in 
his revised ‘Systema,’ where, likewise, “534” has been sub- 
stituted for its longer equivalent. The ascribed localities of 
this and the preceding shell are inaccurate: they are natives 
of Southern Africa. The ‘testa lutea, striarum mucronibus 
albis” is more applicable to granularis, and formed no portion 
of the original description: the colouring was more correctly 
depicted in the ‘Museum Ulrice.’ 
Aatella bulgata. 
The marked individuals (List. Conch. pl. 535, f. 14) in the 
typical collection both demonstrate that the common limpet of 
our own shores has been rightly identified with the vulgata of 
Linneus, and explain the “angulis quatuordecim obsoletis” of 
the description. For in several of the specimens certain of the 
raised striz, which are not, as in the majority of adult British 
examples, of eqtal magnitude throughout, are preeminently 
elevated, a character which, however true of individuals, is not 
essential to the species. As the paucity of T’estacea indigenous 
to the North of Europe naturally facilitates their determination, 
the reference to the ‘Fauna Suecica,’ aided perhaps by the 
abundance of the shell, effected that recognition which would 
scarcely have resulted from the perusal of the ‘Systema.’ For 
not only was the description in that work utterly inadequate 
for the purpose of definition, but even two (Gualt. pl. 8, f. L, 
and Ginanni) of the three figures that were cited as illustrative, 
were designed, in all probability, for the P. cerulea, a very 
closely allied Mediterranean congener. Galtier, plate 8, f. Q, 
quoted in the tenth edition of the ‘Systema,’ but eventually 
discarded from the synonymy, although not so unlike vulgata, 
was apparently copied from part 1, figure 4, of Bonanni’s 
‘ Recreatio ;’ it is there stated to be “ Indica.”
