the body-whoii, their interstices narrower than those between the 

 cingnla, crossing points raised into roundish gemmules. Colour light 

 brown, the uppermost cincture of a darker colour. Spire high, conic, 

 much higher than the aperture ; outlines straight. Protoconch of the 

 only specimen broken ofi, one smooth and convex whorl only left. 

 Whorls about 7, regularly increasing, flatly convex ; base smooth and 

 moderately concave. Suture deep, canaliculated by the cingula. 

 Aperture vertical, subquadrangular, produced below into a very short 

 and open canal. Outer lip denticulated on the outside by the spiral 

 sculpture. Columella subvertical, rounded, slightly sinuate, termi- 

 nating in a blunt point below. Diam. 1'6, height 5 mm. 



Hab. — Near the Bounty Islands, in 50 fathoms (Capt. Bolhms). 

 Type in my collection. 



43. Ceeithiopsis stylifokmis, n.sp. PI. Ill, Fig. 43. 



Shell small, acicular, almost cylindrical, rather thin. Sculpture 

 consisting of three cingula, the uppermost close to the suture and less 

 elevated, a fourth smooth keel on the last whorl, continued from the 

 suture ; crossed by straight axial riLlets, about fifteen on the last 

 whorl; the points of intersection raised to conspicuous rounded gem- 

 mules on the second and third keel, the first, however, remaining 

 nearly smooth. Colour yellowish brown, the first three whorls slightly 

 darker. Spire high, subcylindrical, but tapering towards the apex, 

 very much higher than the aperture ; outlines straight. Protoconch 

 papillate, of one and a half smooth, convex, and shining whorls. 

 Whorls 8 to 9, regularly increasing, convex ; base slightly concave 

 and smooth. Suture impressed. Aperture vertical, subquadrangular, 

 produced below into a very short, open, and emarginate canal. Outer 

 lip sharp, sinuated on the outside by the spiral keels. Columella 

 vertical, straight above, bending over in a curve to the canal below. 

 Diam. I'l, height 3*7 mm. 



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

 Type in my collection. 



44. Ceeithiopsis maeginata, n.sp. PI. Ill, Fig. 44. 



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

 broadly rounded cingula, the last two whorls with a narrow thread 

 margining the suture, and two additional narrow and smooth keels on 

 the body- whorl, bounding the smooth base ; axial sculpture formed by 

 straight, equidistant, and rather broad riblets, about twenty on the 

 last whorl ; crossing points produced into rounded gemmules. Colour 

 white. Spire elevated conic, much higher than the aperture ; outlines 

 faintly convex. Protoconch papillate, the nucleus globular, of one and 

 a half smooth, convex, and polished whorls. Whorls about 8, regularly 

 increasing, the upper ones somewhat convex, the others ilattish ; base 

 slightly concave. Suture impressed, margined on the last whorls. 

 Aperture subquadrangular, produced into a short and open canal, not 

 notched at its base. Outer lips nodulous on the outside, basal lips 

 sinuate. Columella subvertical, straight, truncated below by the 

 oblique upper margin of the canal. Diam. 1, height 2-7 mtn.
