CYPRAA. 191 
in confirming the established opinion. The younger Linné has 
correctly cited “‘ Knorr, Conch. 4, t. 25, f. 4” as illustrative of 
the shell designed by his father. 
Cvprxa ascllus. 
In his revision of the ‘Systema,’ Linneus has properly 
changed the former erroneous reference to Lister (which he 
had appended likewise and more fittingly to cribraria) to “t. 
666,” and has also quoted figures 280, 281 of Martini’s twenty- 
seventh plate. The synonymy thus amended is correct, and 
clearly indicates the Cyprea asellus of authors (Sow. Conch. 
Ill. Cyp. f. 98), examples of which are still preserved in the 
Linnean cabinet, and alone agree with the definition of the 
species. 
Cyprea ervones. 
The Cyprea olivacea of Lamarck (Sow. Conch. Ill. Cyp. f. 
124) is still preserved in the box thus marked in the Linnean 
cabinet, and delineations of that shell, “Mart. Syst. t. 27, f. 
278, 279,” are cited by the younger Linné in illustration of the 
Species designed by his father. This confirms the conclusion 
arrived at by Gray, Deshayes, &c., from a study of the ‘Museum 
Ulvice. As a further elucidation of the difference between it 
and stolida, our author has written ‘ quodque lateribus non 
marginata’’: the dorsal spot on the variety described by Lin- 
neus seems, indeed, the sole point of resemblance. 
Cvprxa cribrarta. 
The Cyprea cribraria of authors (Reeve, Conch. Icon. Cyp. 
f. 81) is preserved in the box thus marked in the Linnean c¢abi- 
net. In the revised copy of the ‘ Systema’ “t. 695” has been 
substituted for the former circuitous reference to Lister, 
“Mart. Syst. t. 31, f. 336” (a not very accurate representation
