etl spiral line a little below the suture, perfectty smooth elsewhere. 

 Body-whorl very large, a trifle higher than one-half the shell-height. 

 Periphery broadly rounded. Aperture elongated, acute behind, 

 rounded in front. Inner lip with a narrow reflexed margin cover- 

 ing lower two-thirds of it. Height G millim. Diameter 1.5 

 millim. Length of aperture 2.5 millim. 



This species looks somewhat like EuUma 2^sUa Watson (Chal- 

 lenger Gastr., pi. 35, fig. 1) from the West Indies Avhich, however, 

 has no spiral line below the suture, and moreover, has the body- 

 whorl as weh as aperture comparatively shorter. 



Fossil occurrence. — Otake (rare), Shito (do).

Shell small, subulate, polished. Apical portion sometimes 

 shghtly curved sidewise. Whorls about eleven, flat, smooth, with 

 sutures indistinct. Body-whorl shorter than one-half the height of 

 the shell. Periphery broadly rounded. Aperture ovately conic, 

 acute beliind, rounded in front. Inner as well as outer lip very 

 obtusely angulate in the middle. Height 6 millim. Diameter 

 1.5 millim. Length of aperture 1.5 millim. 



The living siiells which can be compared with the present are 

 Eiilima acerrima Watson (Challenger Gastr., pi. 36, fig. 1) and 

 Eulima sarissa Watson (loc, cit., pi. 36, fig. 2). The former, how- 

 ever, has the shape of the body- whorl as well as of the aperture 

 difïerent, while the latter is in general more subulate in form.

 a little lower than one-half the shell-height. Periphery rounded. 

 Base rather abruptly narrowed. Aperture ovate, pointed behind, 

 somewhat produced and rounded in front. Margin of inner lip-
