 near the Snares Islands, in 50 fathoms. 



40. Cerithiopsis acies, n.sp. PI. Ill, Pig. 40. 



Shell very small, acicular, rather solid. Sculpture consisting of 

 three equidistant cingula, the uppermost 'very thin and close to the 

 suture, which is margined above by a fine thread ; the last whorl with 

 a fourth spiral ridge emerging from the suture ; the spiral sculpture 

 crossed by slightly oblique axial riblets, also equidistant and of the 

 same width as the interstices, about fifteen on the last whorl ; the points 

 of intersection raised into round gemmules ; the axial sculpture is more 

 prominent than the spiral. Colour white. Spire high and narrowly 

 conical, much higher than the aperture ; outlines almost straight. 

 Protoconch polygyrate, cylindro-conical, of four slowly increasing, 

 strongly convex and smooth Avhorls. Whorls about 10, convex; base 

 slightly concave. Suture deeply impressed. Aperture subquadrangular, 

 vertical, with a short and widely open canal. Outer lip sinuated by 

 spiral sculpture. Columella vertical, slightly sinuate, pointed at the 

 base. Diam. 1-1, height 3'5 mm. 



ITah. — Port Pegasus, Stewart Island, in 18 fathoms (Capt. Bollons). 

 Type in my collection. 



41, Cerithiopsis subantarctica, n.sp. PL III, Pig. 41. 



Shell very small, subulate, rather solid. Sculpture consisting of 

 three cingula, equidistant, with a fourth keel on the last whorl ; crossed 

 by oblique axial riblets, eighteen to twenty on the last whorl ; the 

 points of intersection raised into prominent gemmules. Colour light 

 brown. Spire elevated conical, much higher than the aperture ; out- 

 lines straight or faintly concave. Protoconch polygyi'ate, of four 

 smooth and convex whorls. Whorls about 11, first very slowly 

 increasing, slightly convex ; base concave. Suture impressed, not 

 margined. Aperture vertical, quadrangular, produced below into 

 a short, open canal. Outer lip sharp, denticulated on the outside by 

 the gemmules. Columella vertical, sinuate, rounded, terminating in 

 a point below. Diam. 1-5, height 4-8 mm. 



ITab. — Near the Snares, type, and Bounty Islands, in 50 fathoms 

 (Capt. Bollons). Type in my collection. 



42. Ceeithiopsis canalioulata, n.sp. PL III, Pig. 42, 



Shell small, subulate, solid, with channelled suture. Sculpture 

 consisting of three spiral keels, equidistant, the uppermost weaker and 

 close to the suture, the last whorl with an additional keel arising from 

 the suture'; crossed by oblique straight axial riblets, about twenty on
