180 PEOCEEBINGS OP THE MALACOLOGICAL SOCIETY. 



body-whorl lightly convex, contracted below. Suture linear, false- 

 margined, as is very often the case in JEulima. Aperture slightly 

 oblique, narrow, sub-channelled above, but little narrowed below, 

 "without a canal. Outer lip vertical, rounded below, somewhat 

 thickened and denticulate within. Columella vertical, slightly bent 

 to the left below ; inner lip narrow and smooth, very thin on the 

 straight parietal wall. Operculum unknown. Diameter 2*75, height 

 6-6 mm. 



Sah. — Bay of Islands. 



Distinguished from the nearly allied M. cJioava, Reeve, by the larger 

 size and much higher spire. 



MiTEELLA SUBANTAECTICA, n.Sp. PI. VII, Fig. 5. 



Shell small, acuminate, smooth to the naked eye, polished, semi- 

 transparent, fulvous. Sculpture consisting of fine and dense micro- 

 scopic spiral striae on all the whorls, lightly decussated by the fine and 

 somewhat oblique growth-lines. Colour yellowish brown, with a 

 darker band below the suture, produced by the lower part of the 

 preceding whorl. Spire high, conic, nearly one and a half times 

 the height of the aperture ; outlines straight. Protoconch of one and 

 a half whorls, papillate. Whorls 6, regularly increasing, lightly 

 convex, the last whorl rounded and a little contracted at the base. 

 Sutui'e impressed, but not deep. Aperture oval, subvertical, with a 

 very short, widely open canal. Outer lip sharp, not much thickened, 

 convex, smooth inside, sometimes with a slight contraction below. 

 Columella vertical, somewhat arcuate, bent to the left toward the 

 base ; inner lip narrow, smooth, extending over the faintly excavated 

 parietal wall. Operculum unknown. Diameter 2-7, height 5-4 to 

 6 mm. 



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



Nearly allied to M. paxillus, Murdoch, but not so slender, the 

 spiral strise closer, more numerous, and always present, and the body- 

 whorl not angled. 



MiTEELLA LEPTALEA, n.Sp. PL VII, Fig. 6, 



Shell small, subulate, smooth, shining, thin and pellucid, yellowish. 

 Sculpture consisting of almost obsolete fine microscopic spiral striae, 

 and a few faint spiral ridges on the lower part of the base ; growth- 

 lines fine, straight. Colour light yellowish. Spire subulate, a little 

 higher than the aperture ; outlines nearly straight. Protoconch small, 

 papillate, the nucleus somewhat oblique. Whorls 5, regularly in- 

 creasing, very lightly rounded, the last convex, contracted at the 

 base. Suture linear, false-margined below. Aperture narrow, angled 

 above, slightly contracted below, but without a canal. Outer lip 

 thin and sharp, smooth within, lightly convex, somewhat contracted 

 below. Columella vertical, a little convex; inner lip narrow, smooth, 

 spreading as a very thin glaze over the lightly arcuate parietal wall. 

 Operculum unknown. Diameter 1*8, height 4"5 mm. 



Hah. — Near the Bounty (type) and Snares Islands, in 50 fathoms 

 (Captain J. Bollons).
