166 CYPR^EA. 



C. CINEREA, Gmel. PL 2, figs. 15, 16. 



Ash-brown, sometimes longitudinally painted with jet-black 

 dashes, sides flesh-tinged and similarly painted, base cream-white, 

 interstices between the teeth generally pinkish flesh-color. 



Length, 1-1 -75 inches. 



West Indies. 



Fossil, common in the Pliocene clay beds of Costa Rica (W. 

 M. Gabb). 



C. CLARA, Gask PI. 1, fig. 8. 



Very closely allied to, if not identical with the above. The 

 main difference lies in the teeth, which are smaller. 



Length, about l inches. 



Bab.? 

 C. REEVEI, Gray. PI. 3, figs. 24, 25. 



Differs from C. cinerea, Gmel., in being bluish lavender in 

 color, with the extremities delicately tinted pink. The shells 

 usually present an undeveloped appearance. 

 Length, about 1*5 inches. 



Swan R., Australia. 

 Group B. Margined. 



* Margins not spotted. 

 C. CARNEOLA, Linn. PL 3, figs. 26-30. 



Pale flesh-color, ornamented with four, occasionally five, bands 

 of a deeper tint ; base and sides pale fulvous; teetli and interstices 

 deep purple. Animal red. Length, 1-3 inches. 



Pacific and Indian Oceans. 



This species is extremely variable both in size and shape, and 

 some specimens are quite like the group in which the C. arenosa 

 has been placed. Mr. Sowerby, in Thes. Conch. Cypneida^, calls 

 attention to a variety in which the teeth are not purple-tinted. 

 This is probably the G. Loebbeckeana of Weinkauff (figs. 29, 30), 

 but Weinkauff says of his species, that in addition to this, there is 

 also the absence of the bands of color on the back, whilst 

 Sowerby's figure indicates their presence. Very large specimens 

 of C. carneola, from the Isle of Pines, have been confounded 

 by non-scientific collectors with C. aurantium, Martyn. 



Fossil, the species is common in the clay beds of Costa Rica 

 (Gabb).
