however, an Ancilla that .Sowerby had before him, and Smith was 

 misled by a careless reference in Sowerby's paper. Marginella 

 angustata must be deleted from the South African list. I now have 

 the original specimen of this Ancilla before me, as well as several 

 Others, and find that, though closely related, it is a species distinct 

 from the East Indian angustata Sow. I therefore propose to describe 

 it as 



Ancilla errorum nov. sp. Plate VIII, fig. 2. 



Shell very similar to A. angustata Sowerby, but with a spire that is 

 longer, more acuminate, and less callused. Colour of body-whorl 

 pale, instead of liver-coloured ; colour below columellar band white 

 and sharply defined. Upper part of columella spirally grooved within 

 aperture ; lower part deeply longitudinally grooved as in angustata, 

 but with five grooves instead of three. 



Habitat, Cape Point, 42 fathoms. 



Type, in the Cape Town Museum. 



I am able also to figure the operculum of this species. 



Marginella ^ epipolia nov. sp. PI. YIII, fig. i. 



This very beautiful shell I received from the late Mr. Sowerby as 

 a particularly fine example of M. bairstoivi Sow., and I also procured 

 one similarly labelled from the J. J- McAndrew collection. But while 

 hairstowi has exactly the shouldered body-whorl and general build 

 of mosaica in miniature, M. epipolia has a much longer spire, and the 

 shouldering is almost obsolete. 



The shell is highly polished, whitish ; whorls 5^ ; body-whorl with 

 twelve fine spiral interrupted grey lines, traces of other subsidiary 

 lines, and a good deal of irregular greyish shading ; there are on the 

 grey lines much darker spots at regular intervals. The periphery is 

 well marked by a white band, and the space between periphery and 

 suture is covered with grey flame-shaped axial markings. The pen- 

 ultimate and antepenultimate whorls have the white band immediately 

 above the suture and the same arrangement of flame-shaped markings 

 above. Protoconch yellowish ; columella with four plaits. 



Long., 1 7 '5 mm: : diam. max., 9*5 mm. 



Habitat, dredged in 24 faths., off San Sebastian's Bluff, S. Africa. 



Type in coll. Tomlin. 



Clanculus atricatena nov. sp. 

 Shell broadly and depressedly conical, apex brightly rose-coloured, 

 the rest lighter or darker brown ; there are about nineteen or twenty
