incrassated or angulated, dorsal surface reddish pink sprinkled with 

 white, sparsely overlaid with brown spotting, base and extremities 

 white, young specimens reddish pink unspotted. A subvariety is of a 

 faint lilac or lavender hue, spotted with white, base slightly tinged 

 with yellow, young specimens unspotted. It is an extremely rare 

 variety. 



C. helvola v. timorensis nov. Timor Island, vicinity of N.W, 

 Australia. Shell differing from C. helvola in having white, not lilac, 

 extremities which are calloused, twin callosities at the posterior 

 extremity, dentition, dorsal surface and base same as in type. 



C. poraria L. v. vibex nov. New Caledonia and New Hebrides. 

 Type specimen of considerably larger size than normal examples 

 of C. poraria, and distinguished by a white porcellanous band or 

 stripe not raised but showing quite distinctly, stretching from one 

 extremity to the other, thus dividing the dorsal surface into two equal 

 parts. Some years ago I received from the New Hebrides a specimen 

 of the usual size and appearance of C. poraria, except for the dis- 

 tinctive band, and several shewing the band half completed, i.e., in 

 the exact centre but abruptly curtailed and not reaching to the 

 extremities, at that time I was inclined to consider this as merely a 

 freak of nature, but now having received so magnificent a specimen 

 from New Caledonia, thus evidencing its existence in two different 

 localities, I think it should be classed as a variety. 



C. miliaris Gmelin v. diversa nov. Sharks Bay, West Australia. 

 Shell as in type but scarcely so rotund. Specimens very light 

 in colour, almost white but shewing spotting perfectly ; they are 

 quite distinct from C. eburnea Barnes, the teeth are not so coarse, the 

 enamel of the dorsal surface is not so shining, the interior is coloured 

 pink or pale violet, while the interior of C. eburnea is either white or 

 orange; the specimens are comparatively small. I think the discovery 

 of this variety proves the complete separation of the two species C. 

 eburnea and C. miliaris. 



C. carneola Reeve v. rubiola nov. Hawaiian Islands. Shell 

 resembling type specimens as nearly as possible (where there exists 

 such variety in form, colour and sculpture) except in colouration of 

 teeth which are bright rose pink in contradistinction to the purple 

 hued dentition of C. carneola or the colourless base and dentition ot 

 C. Icebbeckiana Weinkauff, which Cyprcea almost approximates to the 

 distinction of shape which exists between C. exusta and C. talpa, 

 the ends being more produced, the dentition finer, the shape more 

 pyriform than that of C. carneola and the dorsal surface most frequently 

 unicoloured, the cornelian bands being absent from C. labbeckiana or 

 shewing so faintly as to be almost invisible. I have a number 

 specimens, one or two only with bands of colour.
