76 SPECIES OF THE SYSTEMA. 
43 (so constantly transposed by Linneus) exhibits the required 
longitudinal sulci. The citation is corrected, in the copy of 
the ‘Systema’ which belonged to the younger Linné, to “ Rump. 
t. 42, f. D,” which engraving both corresponds with the descrip- 
tion in the ‘Museum Ulrice’ and with the shell so long re- 
cognised for it, the Lucina punctata of more modern writers 
(Sowerby, Genera Shells, Lucina f. 1). 
Venus exoleta. 
Both Artemis exoleta (Poli, Test. Sicil. pl. 21, f. 10) and 
A. lincta of Pulteney are marked for this species in the Linnean 
cabinet: since the former alone agrees with the terms of the 
description, the specific name must consequently be retained 
for it solely. 
The synonymy requires much emendation: the “ Pet. Gaz.” 
is clearly an error for “ List. Conch.” there being no plate 291, 
f. 127 in Petiver’s ‘Gazophylacium’; and the species being 
correctly represented in that plate of Lister’s ‘ Historie Conchy- 
liorum.’ Gualtier’s engravings, though possibly intended for 
this species, are too uncharacteristic for future citation: Lister, 
f. 98 of plate 262 is V. castrensis or an allied species, which ap- 
proaches the Linnean example in shape and colouring. The 
account in the ‘Fauna Suecica’ has been copied from that in 
the tenth edition of the ‘ Systema.’ 
Linneus, in the final edition of his ‘Systema,’ has unwisely 
attached to this species, as a variety, the apparently distinct 
shell which he had previously termed Venus lupinus (ed. 10, 
p. 689). Unmarked examples of the Artemés lupinus (the 
A. lincta of Philippi) are to be found in the typical collection ; 
but their presence, though it strengthens the probability of the 
assumed identification, proves nothing, since the very insuffi- 
cient description is equally applicable to several other shells in 
the Linnean cabinet. 
The V. exoleta of the ‘Museum Ulrice,’ described as being 
white externally, and crusted internally with a pale, yellowish 
substance, was possibly lincta, which occasionally is, I fancy, 
thus stained.
