to the aperture and indistinctly angular in front, the base very convex. 

 The aperture is quite oblique, the upper and baso-columellar margins 

 about equally arcuate, the outer arc more strongly curved. The peris- 

 tome is thin, narrowly but well expanded, the baso-columellar margin 

 reflexed, somewhat dilated towards the columellar insertion.

This is a more compact shell than Eulota fortunei and quite different 

 in sculpture. The generic position is uncertain, until the soft anatomy 

 can be examined. It may belong to the section Eulotella, or it may 

 be a Ganesella. The minute granulation is like some species of the 

 G. japonica group. We do not know of any sinistral Ganesella, but 

 there are many sinistral species of Eulota. 



Dead and bleached shells which have lost the cuticle do not show the 

 granulation described above. The largest example seen measures, 

 alt. 12, diam. 16.5 mm. It is a dead shell. 



Eulota (Plectotropis) scitula P. and H., n. sp. Fig. 4. 



The shell is rather narrowly umbilicate, conic above, convex below, 

 strongly angular at the periphery; uniform chestnut brown. The sur- 

 face is rather dull, finely closely and rather weakly marked wdth growth- 

 striae, which in quite fresh, unworn shells bear short adnate cuticular 

 threads on the base, giving it a sparsely scaly appearance. The last 

 two whorls have also a very close, fine sculpture of beautifully even spiral

strise. The outlines of the conic spire are nearly straight. Whorls 6|-, 

 slowly increasing, moderately convex, the last descending very little or 

 not at all in front, convex beneath. The aperture is strongly oblique, 

 rounded lunate. Peristome thin, narrowly but distinctly expanded, the 

 basocolumellar margins a little reflexed, dilated towards the columellar 

 insertion; ends widely separated, joined by a thin film.
