Genus Cyprcea. 231 



■esontropia, cribellum^ Gaskoiiiii are typically distinct, I should 

 never be surprised at all being eventually united. 



C. carneola (L.). Reeve, Conch. Icon., pi. ii., f. 19 ; 

 Sowb., Thes. Conch., pi. iii., f. 11 — 13. 



Type. — Reddish flesh colour, with four or five bands of a 

 darker hue of the same tint, extremely variable in shape. 

 ]\Iy largest specimen 3^/^ in. long, the smallest full grown 

 I inch. The sides have more or less callous deposits. 

 Every gradation exists between the large elongate shell, 

 the sides not thickened, and the smaller with flattened sides, 

 resembling an Aricia. Teeth purple-violet. Very abund- 

 antly distributed throughout the East. 



{a) Loebbeckeana (y^ Qink^ufT). Sowb.,Thes., pl.321, f 322. 

 No bands of colour on dorsal surface, teeth uncoloured. 

 Mauritius. 'My specimen of what I think is this, is of the 

 usual translucent deep water character of so many Mauritian 

 shells. 



{b) Jiahnaja (var. nov.). Dorsal surface covered with 

 'greenish callous deposit of enamel. Teeth purple, base 

 greenish. Mauritius. From coll. Gloyne, collected by M, 

 Robillard. I have seen a larger specimen of the same 

 variety in the Lincolne Collection of Shells, Peel Park, 

 Salford. An almost exact resemblance to a pickled olive 

 may be traced, suggesting the varietal name. 



{c) propinqiia (Garrett). I think this is only the smaller 

 solid form. Mr. Garrett says the number of teeth is but 25 

 to 30, form of arenosa. Paumotus and Society Isles. Cf. 

 J. of Conch., 1879, p. 117. 



C. Isabella (L.). This common species mainly varies in 

 {a) controversa (Gray). An only apparently sinistral shell, 



back with no black dashes, base broader than the type, teeth 



not quite so fine. 



ifi) limpida (var. nov.). Uncoloured, transparent. Sand- 

 wich Isles. I have likewise seen deep olive green trans-
