Shell small, elongately ovate, smooth, not shining. There is no 

 sculpture except the fine growth-lines. Colour crimson ; dead shells 

 are pinkish. Spire high, conic, about one and a half times the height 

 of the aperture ; outlines straight. Protoconch sometimes slightly 

 oblique, of one and a half smooth whorls, papillate. Whorls 6, 

 regularly increasing, flattish, the last rather large, rounded, and con- 

 tracted at the base. Suture impressed. Aperture vertical, narrowly 

 ovate, lightly channelled above, with a short and widely open canal 

 below. Outer lip thick, with a blunt edge, smooth inside, almost 

 straight above, curved below. Columella vertical, arcuate, with 

 a distinct oblique fold below, bending to the left; inner lip narrow 

 and very thin, smooth. Operculum unknown. Diameter 2"7, height 

 6*2 mm. 



Hab. — Near the Bounty Islands, in 50 fathoms (Captain J. Bollons). 



Alcira l^vigata, n.sp. PI. YII, Fig. 8. 



Shell small, thin, translucent, smooth, faintly shining, elongately 

 oval. Sculpture confined to a few oblique ridges on the lower part 

 of the base. Colour yellowish white, sometimes faintly marbled with 

 pure white. Spire elevated, conic, about the same height as the 

 aperture ; outlines almost straight. Protoconch of one and a half 

 smooth, porcellanous and smooth whorls, the nucleus a little oblique. 

 Whorls 5, regularly increasing, lightly convex, the last rounded and 

 contracted at the base. Suture deep. Aperture subvertical, high 

 and narrow, lightly channelled above, and with a very short, widely 

 open canal below. Outer lip slightly curved, sharp, but little 

 thickened. Columella vertical, with a deep-seated oblique fold at 

 the base ; inner lip very narrow and thin, extending over the flattish 

 parietal wall. Operculum unknown. Diameter 1"8, height 4*1 mm.

Alcira angulata, n.sp. PI. YII, Fig. 9. 



Shell small, elongate fusiform, turreted, spirally ribbed, fulvous. 

 Sculpture : the protoconch smooth, all the succeeding whorls sharply 

 spirally ridged ; two fine spiral threads on the shoulder, the upper 

 close to the suture, a third strong spiral cord upon the angle of the 

 whorls, and three smaller ones below, the lowest fine and margining 

 the suture ; the spiral ornamentation is continued over the whole of 

 the body-whorl, the spirals on the base being closer together; 

 interstices above the base slightly broader than the cingula, with 

 fine growth-lines. Colour yellowish brown, the base lighter. Spire 

 elevated, conic, turriculate, about one and a half times the height of 

 the aperture. Protoconch conical, smooth, of two whorls, the nucleus 

 small, the second whorl relatively high. Whorls 6^, regularly 

 increasing, distinctly shouldered, lightly convex below the angle ; 

 body-whorl high, moderately convex, contracted below. Suture 

 linear, bimarginate. Aperture narrow, subrhomboidal, the margins 

 parallel, angled above, with a very short and broad canal below.
