The imperforated Natica. Shell with a covered umbi- 

 licus, globose, solid, spire somewhat exscrted, obtuse, 

 whorls somewhat eoncavely impressed round the 

 upper part, then convex, aperture semilunar, colu-

SowEEBY, Zool. Beechey's Voyage, p. 135. pi. 37. f. 1. 



Hab. Buffalo, Cape of Good Hope. 



A very distinct solid species, encircled beneath the su-

 the remainder of the shell being freckled with dots of the 

 same colom-. The callosity thickly overspreads the um- 

 liilicus.

The black-modth Natica. Shell with a covered um-

 whorls faintly eoncavely excavated round the upper 

 part, obliquely striated, strife almost obsolete, aper-

 obsoletely pHcately striated, aperture ovately ear- 

 shaped, columella tliiu, umbilicus small, nearly filled 

 with the callosity ; fulvous-brown, aperture stained 

 with violet. 



Deshayes, Guerin's Mag. de Zool. pi. 45. 



Hab. Kamtschatka. 



There is but a faint tinge of violet in the specimen of 



this species here figured, but the colour is well shown in 



the original figure of M. Deshayes.
