42 SPECIES OF THE SYSTEMA. 
Gellina seobtwata. 
The Tellina scobinata (Sowerby, Genera Shells, Tell. f. 2) of 
authors still remains in the typical collection, and alone agrees 
with the description of this species. “ List. t. 302, f. 143” is 
correctly cited in the copy of the younger Linné. 
Sellina Vactea. 
Dr. Philippi, who has bestowed much pains upon the deter- 
mination of the Mediterranean Testacea mentioned by Linnzus, 
remarking that the term “ gibba” was peculiarly inapplicable 
to the Lucina lactea of authors, has transferred the name to 
that tiny bivalve which he had previously called Luc. fragilis. 
He has overlooked, however, the “ semine Lupini albi major,” 
a standard of size which demands that the Linnean species 
should decidedly exceed the magnitude of TJ’. balaustina and 
carnaria, which latter are expressly declared to be as large as 
the seed of a white Lupine. Our author, too, who has noticed 
the absence of teeth in his Venus edentula, would scarcely have 
omitted to remark the same peculiarity in Philippi’s fragiis. 
An examination of his cabinet has shown what Linnzus, who 
must have supposed that the Mediterranean specimens were the 
young of the larger shell, really intended to indicate. In one 
of its drawers there may still be discerned a small example of 
the Lucina globosa (Chemn. Conch. Cab. vol. vii. f. 430, 431), 
which alone accurately corresponds to the Linnean description, 
is not unlike the very rude quoted figure of Gualtier (intended, 
however, for the Zuc. lewcoma), and is, moreover, partly marked. 
The cypher 5 still remains, and as the definition of no other 
species in either edition of the ‘Systema’ which contains a 5 
among the numerals that indicate its position (except perchance 
that of Venus incrustata, Number 115 of the tenth issue, 
whose hinge, however, answers not to the requirements of the 
‘Museum Ulrice’), will at all correspond to the characters of 
this type, save Number 50 of the tenth and 65 of the twelfth
