CYPlliEIDiE. 
Cyiwcua. The monograph of this genus contained in Sowerhy’s ‘ Thesaurus 
Oonchyliorum,’ parts xxvi.-xxviii., contains, in 58 pages and 31 plates, descrip- 
tions and ligures of 187 species, the latter of natural size. The genus is 
taken hy the author in the old Linnsean sense, Trivia being made a subgenus j 
and there are besides seven subdivisions of Cyprcea proper and two of Trivia 
adopted. Numerous notes, which serve chiefly to point out the distinction of 
closely allied species, are added to the descriptions.

where also several particulars concerning varieties or monstrosities of known 
species will be found.
