of about equal length. Aperture small; columella concave, 

 bearing four strong teeth, which extend about two-thirds up 

 the pillar, and extend well out on to the base of the shell; 

 outer lip very massively thickened, much rounded, with a 

 strong tubercle within, placed near the upper third. 



Long. 5, lat. 3 mill. 



Table Cape, several specimens. 



Remarkable in the genus for its tall spire and small 

 short aperture. It makes some approach to the recent M. 

 allporti, Ten.-Woods. 



PI. IV., fig. 5. 



Haurakia crassicosta, Sp. nov. 



Shell minute, broadly turbinate. Whorls five, the two 

 apical smooth and polished; suture well impressed. The first 

 adult whorl has about 9 to 10 closely set axial ribs in a half 

 turn; the second has 6 to 7 much stronger ribs; and the body 

 whorl about 5 strong rounded ribs, separated by deep fur- 

 rows of equal width; these ribs cease near the centre of the 

 whorl, the base being quite smooth. Aperture roundly-oval; 

 columella very convex. 



Long. 2, lat. 1.5 mill. 



Table Cape, 2 specimens. 



This resembles H. tateana, Ten.-Woods, in size and 

 general appearance, but has much fewer and stronger ribs. 



PL IV., fig. 6. 



Turris conspicua, Sp. nov. 



Shell very large, fusiform, spire and aperture about 

 equal. Whorls about eight, rounded; suture impressed. 

 Aperture narrow. The sculpture indicates a fairly deep 

 sinus immediately below the suture. The upper whirls are 

 faintly coronate at the angle, and ridged by lines of growth; 

 and are concentrically finely Urate all over. 



Long. 83, lat. 24 m.ill., or 3| x 1 inches. 

 Table Cape, two examples. 



This is a very fine conspicuous form, and must be ex- 

 tremely rare, as these were the only specimens taken by Mr. 

 Atkinson during many years* collecting. 



It would seem to approach the Turrid genus Genota.
