184 PKOCEEDINGS OF THE MALACOLOGICAL SOCIETr. 



sculpture. Colour white, but fresh shells are vitreous. Spire elevated, 

 conic, about half the height of the aperture. Protoconch obtuse, 

 rounded. Whorls 3, the last high, moderately convex, narrowed 

 towards the base, the spire-whorls flattish. Suture superficial. 

 Aperture oblique, narrow, widening below, lightly channelled above, 

 truncated and flatly rounded at the base. Outer lip slightly convex, 

 thickened at the middle, with a low outer varix, smooth inside, retro- 

 current towards the suture, and with a shallow sinus. Columella 

 oblique, with four equidistant strong plaits, the lowest twisted and 

 extending to the basal margin. Diameter 1"5, height 3 mm. 



Rah. — Foveaux Strait, in 15 fathoms; type, near tbe Snares and 

 Bounty Islands, in 50 fathoms (Captain J. Bollons). 



Maeginella (Glabella) amcena, n.sp. PI. VII, Fig. 15. 



Shell small, ovate, rather solid, smooth and polished, with a 

 moderately raised spire, white. There is no sculpture. Colour white, 

 fresh shells vitreous. Spire conoidal, with a blunt apex, a little less 

 than half the height of the aperture ; outlines straight. Protoconch 

 very small, broadly rounded. Whorls 3, the spire-whorls flat, body- 

 whorl large, convex, somewhat inflated above, narrowed towards the 

 base. Suture indistinct, not impressed. Aperture sligbtly oblique, 

 high and narrow, the margins subparallel, lightly channelled above, 

 truncated and not notched below. Outer lip somewhat convex, 

 thickened, the inner margin faintly and minutely crenate, with an 

 outer varix which does not extend much upon the spire, lightly 

 sinuate above. Columella oblique, straight, with four nearly equi- 

 distant strong plaits, the upper two almost transverse, the lower two 

 more oblique, the lowest extending to the basal margin ; inner lip thin 

 and transparent. Diameter 2-4, height 4'2 mm. 



E.ab. — Near the Snares Islands, in 50 fathoms (Captain J. Bollons). 



This species is very nearly allied to M. hehescens, Murd. & Sut., but 

 is distinguished from it in being a little larger and more ventricose, 

 having the spire slightly lower and broader, the spire -whorls flat, the 

 protoconch much smaller, the suture not impressed, and the outer lip 

 minutely crenate. 



Drillia chordata, n.sp. PI. VII, Fig. 16. 



Shell small, fusiform, fairly solid, whitish ; suture strongly margined, 

 whorls angulated by a row of large nodules, spire high, anal sinus 

 moderately deep. Sculpture consisting of a row of large oval nodules 

 on the middle of the whorls, about fourteen on a whorl, those on the 

 last two whorls somewhat stretched out towards the suture below, and 

 incised in the middle by a spiral linear groove ; a very strong spiral 

 cord margines the suture below, and a fine thread above ; the latter is 

 continued as a rather strong cord on the body- whorl, and is succeeded 

 below by a similar cord ; the base of the body- whorl is adorned with 

 fine spiral threads, close together upon the beak ; the whole sculpture 

 crossed by very fine, strongly flexuous, and oblique growth-lines. 

 Colour whitish. Spire high, conic, somewhat less than twice the 

 height of the aperture. Protoconch of two whorls, which are
