Shell fusiform, rather thin, white, with epidermis yellowish-ashy, with 
five equally convex whorls, with spire longer than twice the last, with 
distinct suture aperture widely open, equaling half the length of the shell, 
with outer lip distinctly emarginate to the suture, and thence equally 
arcuate. Surface obscurely reticulated with crowded spiral lines narrowly 
impressed and with longitudinal lines a little more conspicuous; operculum 
of the usual form. (Translation.)

Shell small, elongate, ovate, compressed, with about six whorls and a 
rather large smooth nucleus; transverse sculpture of, on the last whorl, 
about 26 broad flattened waves, strongly flexed, most elevated over the 
fasciole, and becoming narrower and less prominent anteriorly; the outer 
angle of the anal notch is rather prominent and makes an angulation espe¬ 
cially of the earlier whorls, which fall away in a peculiarly flattened manner 
to the suture; longitudinal sculpture of fine sharp grooves, which pass 
uniformly over the ribs and interspaces, are somewhat stronger on the 
earlier whorls and very uniform, only a little coarser on the canal. The 
notch is more marked than usual in Bela ; the shell is pure white and the 
epidermis grayish yellow and quite strong. Length of shell, 9; of aperture, 
4.7; width of shell, 2.3 mm. (Dali.)

Shell small, white, with a minute, smooth nucleus and five subsequent 
whorls; suture distinct, anal fasciole narrow, constricted, obscure; axial 
sculpture of (on the last whorl 26) narrow well-defined ribs, slightly 
peripherally prominent on the early whorls, with narrower interspaces, 
extending from suture to suture and on the last whorl to the canal, slightly 
protractively arcuate; there are also fine, regular, incremental lines; spiral 
sculpture of numerous fine sharp striae with subequal interspaces, which
