SUTEK : ON MOLLIJSCA FEOM NEW ZEALAND. 29 



spirally stiiate ; the succeeding whorls have on the upper third a strong 

 spiral cord, and below it two smaller ones, the lower of which margins 

 the suture ; on the last whorl the whole of this sculpture is more 

 prominent, and on the base is a fourth cord, parallel to the columella ; 

 the entire surface is ornamented with dense axial foliations, crenulating 

 the spiral riblets. Colour white. Spire graduate, much higher than 

 the aperture ; outlines very little convex. Protoconch conspicuous, 

 globular, of one and a half whorls. Whorls 4^, regularly increasing, 

 concave from the suture to the first cord, turned inward in a straight 

 line to the suture below ; base convex. Suture not much impressed. 

 Aperture sub vertical, ovate, slightly angled above. Peristome con- 

 tinuous, thick, and blunt. Basal lip slightly expanded. Columella 

 very short, vertical, nearly straight. Operculum unknown. Diam. "8, 

 height 2 mm. 



Hob. — Near the Snares Islands, in 50 fathoms (Capt. Bollons). 



Nearly allied to R. Suteri^ Hedley, which, however, is much 

 broader, has the protoconch smooth, two spiral cords on the third 

 whorl, and lacks the foliated axial sculpture. Type in my collection.

21. RissoA (Cingttla) lampea, n.sp. PI. II, Fig. 25. 



Shell minute, ovate, imperforate, translucent, polished. Sculpture : 

 sometimes a few microscopic distant spiral lines are present on the 

 upper whorls, but more often the shell is perfectly smooth. Colour 

 white. Spire conic, higher than the aperture, outlines slightly 

 convex. Protoconch small, globose, and smooth. Whorls 5, slightly 

 convex, the last rounded, but somewhat flattened below the suture ; 

 base convex. Suture not much impressed, margined below. Aperture 

 oval, vertical, angled above. Peristome continuous, slightly thickened 

 and expanded. Columella short, arcuate. Operculum unknown. 

 Diam. '8, height 1'5 mm. 



Rah. — Titahi Bay, Cook Strait, in sand (Miss M. Mestayer). Type

22. RrssoA (Cingula) eoseocincta, n.sp. PI. II, Fig. 26. 



Shell minute, ovate, rimate, polished, thin, translucent, with pink 

 and white spiral bands. There is no sculpture, except for fine 

 microscopic oblique growth-lines. Colour : the first three whorls are 

 pink, the last whitish with a narrow pink band below the suture, 

 a second just below the periphery, and a third upon the base ; some- 

 times the last whorl is also pinkish, and the lighter bands are only 

 faintly visible. Spire conical, higher than the aperture ; outlines 

 a little convex. Protoconch small, broadly rounded, smooth. Wiiorls 

 4, flatly rounded, the last rather large and somewhat inflated ; base 

 convex. Suture not deep. Aperture vertical, roundly oval, slightly
