Having thought it well to bring under the notice of the scientific 

 world some varieties of Cyprcca hitherto unnoticed, I wish to draw 

 attention to the following: — 



Cypraea tigris L. v. lineata nov. Fiji. Differing from the 

 type in possessing a number of hair-like lines, passing longitudinallj' 

 across the dorsal surface, from the anterior to the posterior extremity. 

 I do not think these can be lines of growth, as I have one specimen 

 in which the lines are transverse, but do not extend over the whole 

 surface; also three specimens and several others not so fine or 

 distinctly marked. 



C. mappa L. v. viridis nov. New Caledonia. Two uncommon 

 varieties, one with the dorsal surface suffused with a greenish tint, 

 base coloured rose pink, columella side adorned with central brownish 

 blotch; in another specimen both dorsal surface and base are coloured 

 green, especially the base which does not show any blotch. Another 

 specimen from Maldon Island shows a rich dark brown dorsal surface 

 relieved by the usual markings. The margins are adorned with large 

 black spots, which also encroach on the sides of the shell;- the spotting 

 is similar to the marginal spots of some specimens of C. tigris: there 

 is a dark basal blotch. 



C. bregeriana Crosse v. barbara nov. New Caledonia. Shell 

 differing from C. bregeriana in the fineness of the dentition and with- 

 out the violet coloured interstices, interior lined with white, not violet 

 purple as in C. bregeriana. The shape is not pyriform but straitened 

 and more cylindrical, dorsal surface depressed and sculpture adorning 

 it consisting solely of the embedded white spotting, which extends in 

 unbroken continuity over the entire surface of the shell. Margin 

 maize or saffron coloured, having brownisli blotch on the centre of the 

 labium. Dorsal surface light cream colour. The type specimen 

 unfortunately was not a living one and the dorsal surface is somewhat 

 eroded, but portions remain entire. There is a very obvious divergence 

 from C. bregeriana (in which the embedded white specks are confined 

 to the margins and the dorsal surface is thickly covered by olive 

 brownish freckles on a greenish-tinted ground, and the centre darkly 

 banded across, the margins are more or less plentifully sprinkled by 

 large dark coloured spots, extremities also spotted). A good illustra- 

 tion of C. bregeriana is given in 'Thes. Conch.,' figure 536. The 

 dissimilarity of this variety is therefore very apparent. 



C. helvola L. v. borneensis nov. Borneo. Shell differing 

 from C. helvola in being smaller in size and having narrower sides, not
