340 EULIMELLA. 



E. ACICULA, Phil. PI. 76, figs. 59-61, 54, 62, 



Rather thin, semitransparent, polished, glassy white in live, 

 milk-white in dead specimens ; whorls 8-9, narrow, flattened, 

 periphery scarcely angnlated. Length, 4*33 mill. 



Europe. 



Monterosato has changed the name to E. commutata on 

 account of Auricula acicula, Lam., a fossil species which is a 

 very doubtful Eulimella. 



Yar. TURRTS, Forbes. 



Shell of nearly equal breadth throughout, with rather convex 

 whorls. 



Yar. VENTRICOSA, Forbes. 



Shell thinner, with tumid whorls and deeper suture. 



E. gracilis, Jeffreys ; E. turritellata, Requien, and E. affinis, 

 Phil. (fig. 62), are synonyms. Monterosato, who considers ven- 

 tricosa a distinct species, has described a var. minima (unfigured). 



Yar. OBELISCUS, Jeffreys. PI. 76, fig. 54. 



Shell smaller and narrower, with more compact whorls. 



E. STRIATULA, Jeffreys. PI. 76, fig. 55. 



Yery slender ; whorls 8-9, flattened, suture distinct ; white 

 with distinct spiral striae. Length, 2-5 mill. 



Spezia, Italy. 

 E. NITIDISSIMA, Mtg. PI. 77, fig. 79. 



Yery thin, transparent, lustrous; whorls 7 (besides the nucleus), 

 convex, finely spirally striate, white. Length, 2-5 mill. 



Europe. 

 E. CRASSA, Jeffreys. PL 77, fig. 81. 



Thick, opaque, glossy, smooth, white ; whorls 8-10 (?), flat- 

 tened, suture slight; lip thick, with 8-LO spiral striae within, 

 columella with a strong spiral tooth. 



Length (a fragment only), 6 mill. 



Mediterranean Sea. 



This species has the mouth of an Odostomia, but the form of 

 the shell and want of sculpture together constitute an Eulimella 

 as to external appearance.
