and strongly ribbed by about sixteen prominent, rather narrow, ob- 

 tuse, nearly straight ribs, which rise into angular points or small, 

 obtuse nodules at the shoulder ; the interspaces are wider than the 

 ribs and strongly concave. The ribs and interspaces also extend 

 across the subsutural band to the suture, becoming small above the 

 shoulder. The whole surface is covered by rather slender revolving 

 cinguli, in the form of thin, raised lines, which are most conspicuous 

 in the interspaces and more or less obsolete on the ribs. On the sub- 

 sutural band the spiral lines are finer and closer, and often indistinct 

 toward the sutui-e, but on the anterior part of the body-whorl they 

 become somewhat coarser and wider apart. The last whorl is much 

 swollen and has the shoulder somewhat rounded, while on the upper 

 whorls there is often a distinct carina at tlie shoulder. The nucleus is 

 small and prominent, smooth, and consists of about one and a half 

 whorls, of which the apical is turned up obliquely and incurved. The 

 aperture is ovate, broadly rounded externally, and more strongly ex- 

 cavated at the base of the columella. Canal a little elongated, nar- 

 row, constricted at the base by the incurvature of the outer lip, and 

 with the opening oblique, owing to the form of the columella margin, 

 but not bent. Columella nearly straight, its inner margin forming a 

 well-marked sigmoid curve, and strongly obliquely twisted at the 

 anterior end.

This species has some resemblance to certain forms of the northern 

 Bela scalaris. It is a thinner and much more delicate shell, Avith 

 finer sculpture, and having the whorls less strongly angulated and the 

 form of the aperture and canal somewhat different. 



Spirotropis ephamilla Verriii, sp. nov. 



Shell elongated-fusiform, \yith a high, somewhat turreted spire, 

 and a moderately elongated, slightly curved canal. Posterior sinus 

 situated considerably below the suture, close to the shoulder. Whorls 

 moderately convex, strongly angulated near the middle. Below the 

 suture is a broad, flattened (tr slightly concave subsutural band, 

 covered with coarse and slightly raised spii-al lines, with a series of 

 small, rounded nodules close to the suture, and crossed by strongly 

 excurved, sinuous lines of growth, parallel to the edge of the jjosterior 

 sinus, and receding most at the shoulder, where there are usually two
