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 suture, 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 the 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 andincurved. 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. Tt is a thinner and much more delicate shell, with 
finer sculpture, and having the whorls less strongly angulated and the 
form of the aperture and canal somewhat different. 
Spirotropis ephamilla Verrill, sp. nov. 
Shell elongated-fusiform, with 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 or slightly concave subsutural band, 
covered with coarse and slightly raised spiral 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 posterior 
sinus, and receding most at the shoulder, where there are usually two
