8. Two Albino Varieties of Cyprea erosa Linneus, 
By E. VREDENBURG. 
The two varieties of Cyprea erosa described in this com- 
munication were noticed during the sorting and classification 
of the Cyprzeide in the collections of the Indian Museum. 
Cypra@a EROSA Linneus, var. KAOLINICA var. nov. 
r d derately expanded continuous crenulated ri 
small spire is concealed beneath a very small shallow 
depression near the apex of the posterior notch. e greatest 
h 
width and greatest thickness are situated only slightly nearer 
extremity is more gradual than towards the posterior ex- 
tremity, in which latter direction the elevation, at first, scarcely 
decreases and then falls rapidly on approaching the posterior 
extremity. A few lines of growth are visible on the dorsal 
surface, especially on the right side. Both apertural outlets 
are dorsally notched. The anterior notch is of a rather 
shallow semi-circular shape, slightly constricted ventrally 
by the ridge-like terminations of the columella and outer 
its depth is not fully appreciable in a dorsal aspect. The 
posterior notch is narrower, deeper, and more inclined to 
the axis, so that it is very conspicuous in a dorsal aspect 
of the shell. It is situated almost symmetrically, its anterior 
deflection towards the left being scarcely appreciable. Its 
ai margins are parallel until they join round the apex 
of the notch in a small semi-circular are. All round the 
margins and round the terminal notches, the dorsal surface 
is bordered by a conspicuous, though not very broadly ex- 
of dissymetry, by the rather narrow, nearly straight aperture, 
searcely deflected posteriorly, scarcely expanded anteriorly. 
At its very gradual connection with the base of the penultimate 
whorl, the columella is practically vertical.
