REPORT ON THE GASTEROPODA- 519 



Shell. — Smallish, thin, glossy, attenuated, with a rounded longish base, a symmetrical 

 spire, a blunt biggish tip, flat whorls, a scarcely visible suture, and an ovate mouth. 

 Sculpture : There are very faint microscopic lines of growth, with a very feeble continuous 

 indication of an old labial varix on successive whorls. Colour translucent white with a 

 slight yellow tinge ; the surface is brilliant. Apex is largish, blunt, and rounded, being 

 somewhat spread out and flattened down. Spire: as the whorls in their growth increase 

 very little in breadth, the breadth at the periphery is slight ; and the apex being large, 

 the form of the spire is somewhat cylindrical in comparison with other species of the 

 genus ; * it is also straight, with nearly symmetrical profiles. Whorls 9, of regular 

 increase ; they are all small, and not in the least convex ; the base is slightly elongated 

 and is rounded. Suture scarcely visible, but indicated by the interior septum. Mouth 

 ovate, pointed above. Outer lip very regularly curved ; its edge, which is sharp and 

 thin, retreats above, is rounded and promineut in the middle, where it is slightly 

 patulous ; in front it is extremely so. Inner lip very direct in its oblique course from 

 above to the point of the short pillar, where it turns over a little abruptly, joining the 

 basal lip : there is a thin glaze on the body, and on the pillar the narrow edge is slightly 

 reverted. H. - 15 in. B. 004. Penultimate whorl, height - 029. Tip of apex, breadth 

 0-008. Mouth, height 0-04, breadth 0'027. 



The shape of this species is somewhat like that of an Aclis ; but the texture of the shell and 

 form of mouth are unmistakably those of Eulima. It is a little like Eulima stenostoma, Jeffr., but 

 is more cylindrical and compressed, with shorter whorls and a much smaller and relatively broader 

 mouth.

Station 24. March 25, 1873. Lat. 18° 38' 30" N., long. 65° 5' 30" W. Off Culebra 

 Island, AVest Indies. 390 fathoms. Pteropod ooze. 



Shell. — Smallish, translucent, thin, glossy, rather attenuated, with a subconical base, 

 a symmetrical spire, a biggish but bluntly-pointed tip, flat whorls, a distinct linearly 

 impressed suture, and an oval mouth. Sculpture: There are many close-set, fine, 

 microscopic lines of growth. Colour translucent white, with a glossy surface. Apex is 

 largish, but the first whorl contracts a little, and the extreme tip, which rises slightly on 

 one side, is very bluntly pointed, or at least not perfectly rounded. Spire conical, 

 symmetrical, with a slight sudden contraction toward the top. Whorls 9, of very regular 

 increase ; they are all small and not in the least convex, except the first three, which are 

 slightly so. Suture a little oblique, linearly impressed, except in the case of the first 

 1 It is from this the name is derived. - y6;j.<f>o;, a nail.
