188 SPECIES OF THE SYSTEMA. 
revised copy of the ‘Systema’ the erroneous reference to 
Lister has been changed to 684 (this figure represents an im- 
mature /ynz), and “Mart. Syst. t. 23, f. 231” has been rightly 
added to the synonymy. The cited delineations in Gualtier 
and Petiver are usually quoted for this Cowry: the latter, how- 
ever, is not characteristic. 
Cyprxa tsabella. 
In the revised copy of the ‘Systema’ “ List. Conch. 660” 
replaces the former erroneous reference to that work, and 
“ Mart. Syst. t. 27, f. 275” is likewise quoted, and justly so, as 
illustrative. The synonymy thus amended is correct, and, since 
it harmonises with the description, no doubt can be felt that 
the shell represented in the cited engravings (Cyprea Isabella, 
Sow. Conch. Ill. Cyp. f. 98), and of which specimens are pre- 
served in the Linnean collection, was the species designed by 
our author, 
Cpyprea opr. 
Deshayes has remarked, that a perusal of the description of 
this Species in the ‘Museum Ulvrice’ banishes all doubt as to 
the identity of the Linnean shell with the Cyprea adusta of 
authors. The accuracy of this conclusion is demonstrated by 
the reference “ List. Conch. t. 657, bona,” which was written 
by Linneus in his revised copy of the ‘Systema.’ That en- 
graving, indeed, was by far the best representation extant of 
the shell intended. Gualtier’s cited delineation has been gene- 
rally regarded as designed for the species, and that of Rum- 
phius, although rarely quoted for it in modern works, is not so 
unlike it. As to the wretched figure in Bonanni, which was 
not inserted in the synonymy of the earlier edition, it was 
evidently drawn from a polished specimen of some other 
Cowry, yet reminds one slightly of the present species. “ Si- 
milis ceterum Capiti-serpentis” has been erased by our author 
in his revised copy.
