10 THE NAUTILUS. 
NOTES ON THE GENUS CYPREA. 
BY JOHN H:. CAMPBELL. 
Since the publication ‘of the latest monograph on the genus 
Cypreea—that by Mr. Roberts in Tryon’s Manual of Conchology 
four new species have been described, viz :— 
Cyprea amphithales Melvill, South Africa. 
Cyprea caput-draconis Melvill, Hong-Kong. 
Cyprea Hungerfordii Sowerby, Hong-Kong. 
Cyprea Rashleighana Melvill, hab. unknown. 
Each of them has been described, apparently, from a single spec- 
imen, and it is not at all certain but that two of Mr. Melvill’s species, 
amphithales and caput-draconts may turn out to be mere varieties. 
In Mr. Melvill’s “Survey of the genus Cypriea,” reprinted in 
pamphlet form in Manchester, England, last year, a large number 
of new varieties of known species are described—some of them 
founded upon mere color variations. Most of them seem to me un- 
necessary additions to shell nomenclature. Tryon and Roberts 
recognized 146 species of Cypreea proper and 40 species of Trivia— 
making 186 species in the genus. Mr. Melvill, in his survey, differs 
with them upon some points. He changes C. princeps, Gray, to C. 
valentia, Perry; C. undata, Lam., to C. diluculum, Reeve; and C. 
turdus, Lam., to C. ovata, Perry; reduces from specific to varietal 
rank, C. reticulata, Martyn; C. coxi, Brazier; C. polita Roberts ; 
C. semiplota, Mighels; C. cernica, Sowerby; C. coxeni, Cox; C. 
sophie, Brazier; C. microdon, Gray; C. macula, Adams; and C. 
fuscomaculata, Pease; and advances to specific rank the following 
varieties: C. caput-anguis, Phil; OC. fabula, Kiener; C. coffea, 
Sowerby ; C. menkeana, Deshayes; C. brevidentata, Sowerby; C. 
bregeriana, Crosse; C. comptoni, Gray; C. depauperata, Sowerby ; 
and C. scabriuscula, Gray. 
I have lately received a fine specimen of C. bregeriana, Crosse, 
New Caledonia, from Mr. G. B.Sowerby, of London, who writes to me 
that he is now of the opinion that it is a good species and not a va- 
riety of C. walkeri, Gray, as he thought it to be when he published 
his monograph in the Thesaurus. Mr. Roberts also make it a 
variety of C. walkeri. Weinkauffand Melvill give it specific rank, 
as does also Mr. Richard C. Rossiter, of New Caledonia. I think it 
is, undoubtedly, agood species. The white specks are characteristic 
and are not found in C. walkert. 
A large series of specimens of C. cervus Linn. and C. exanthema 
Linn., which I have in my collection, leads me to doubt whether 
these two species are really distinct. No authentic localities outside 
of Panama and vicinity, West Indies, Florida and Southeastern 
United States are known in connection with either of them, and 
they are found indiscriminately in the localities named. A beauti- 
ful set of specimens of C. cervus, from the South Florida Keys, are 
in the Academy of Natural Sciences of Philadelphia. I have spec-
