 Plate 10, fig. 2. 



Shell small, very elongate-conic; ground color yellowish, upon 

 which are superimposed numerous irregular blotches and flammu- 

 lations of varying shades of brown, which usually are preceded by a 

 white patch. Frequently there is a row of distantly spaced, light 

 blue dots near the suture. Nuclear whorls two, well rounded, form- 

 ing a depressed, flattened apex. Postnuclear whorls well rounded, 

 appressed at the summit, and marked by exceedingly fine lines of 

 growth only. Periphery of last whorl rounded. Base rather short, 

 well rounded. Aperture almost circular; outer lip thin, showing the 

 exterior markings within; inner lip well curved and slightly reflected 

 over the base; parietal wall covered with a thin callus.

 from Port Alfred (Coll. No. 240). The type has three and one-half 

 post nuclear whorls and measures : Length, 3.5 mm. ; diameter, 2.7 mm.
