Shell rather thin, light ovate, clothed with shining olive- 

 brownish thin epidermis, here and there streaked in an oblique 

 direction with narrow stripes or lines of a deeper shade of the 

 same colour; spire obtusely conical, terminated by a rounded, 

 blunt apex; whorls 63^ gradually increasing, sculptured by oblique 

 lines of growth, which are granulated on the upper portion of the 

 whorls ; the granules are oblong and vanish almost entirely on the 

 lower third part of the upper whorls, and are only traceable for 

 a short distance below the suture on the body-wliorl. The extreme 

 upper edge of the whorl bordering the suture is pale and crenu- 

 lated; aperture irregularly ovate, acuminated above and produced 

 only moderately belov,- the truncature of the columella, equalling 

 about half the entire length of the shell, somewhat iridescent, 

 within bluish or vinous white; peristome thin, simple, everywhere 

 arcuate; columella well arched in the middle and tortuous 

 beneath, oblique but narrowly truncate at the base, covered with a 

 v/hitish enamel faintly tinged VN'ith pink, which extends in the form 

 of a very thin layer over the whorl to the termination of the outer 

 lip. 



This species is very distinct from any other v/ith which I am 

 acquainted. It is remarkable for the simplicity of its coloring, 

 the rotundity of the whorls, and its glossy surface. Several speci- 

 mens were presented to the British Museum in 1S60, by Dr. P. 

 Sutherland, by whom they v/ere collected at Port Natal whilst 

 surveying that part of South Africa.
