gracilis, Forbes and Hanley. It most resembles Eulima sarissa, Wats. ; but it is, as compared to tliat 

 species, slimmer, the base is much shorter, the mouth more regularly oval, the apex blunter, the 

 spire more flexuous.

Station 344. April 3, 1876. Lat. 7° 54' 20" S., long. 14° 28' 20" W. Ascension 

 Island. 420 fathoms. Volcanic sand. 



Shell. — Very small, with compressed rounded outlines, glossy, with a slightly impressed 

 suture, flat whorls, a short rounded base, oblique pear-shaped mouth, and a small blunt 

 rounded tip. Sculpture : none. Colour glossy porcellanous white. Apex small, but very 

 blunt and round. Spire conical, unsymmetrical. Whorls 9, short, broad, flat ; the last, 

 which is small, is bluntly angulated at the periphery, and has a blunt rounded base. 

 Suture minutely but sharply impressed. Mouth small, oblicpue, pear-shaped with a gutter 

 in front, and altogether very like the mouth of a Rissoina. Outer lip thick and strong, 

 but with a sharp edge ; it is well arched ; the edge retreats above, is very prominently 

 rounded in the middle, and retires in front, where it is patulous. Inner lip : a narrow 

 defined glaze crosses the body, which is barely convex ; this glaze spreads a little at the 

 concave base of the pillar, which is extremely short and narrow, and has a sharpish edge. 

 H. 0-085 in. B. 0"03. Penultimate whorl, height 0-014. Tip of apex, breadth 0-004. 

 Mouth, height 0-024, breadth 0-017. 



This small species is like some of the small Eulimellas, but is a true Eulima.

Eulima campyla, Watson, Prelim. Report, pt. 17, Journ. Linn. Soc. Lond., vol. xvii. p. 122, sp. 14. 



Station 185b. August 31, 1874. Lat, 11° 38' 15" S., long. 143° 59' 38" K Raine 

 Island, Cape York, North Australia. 155 fathoms. Coral sand. 



Shell. — Subfusiform, thin, with a narrow direct semioval mouth, a long subconcave 

 base, flat whorls, an impressed suture, slightly convex profiles, and a small blunt tip. 

 Sculpture : there are a few very slight lines of growth. Colour hyaline to porcellanous. 

 Apex small, but very bluntly rounded, a little tumid ; the extreme tip rises a little on 

 one side. Spire : laterally it is straight ; but the whole shell bends forward in the plane 

 of the mouth, 3 and the apex has a bend over of its own. Whorls 9, those toward the 

 apex are slightly convex, those lower down are less so ; the earlier ones are of slow and
