all the surface to the tip of the canal. The cinguli are everywhere 
crossed by very numerous and regular, thin, raised lines or riblets, 
which are usually of nearly the same size as the cinguli, but frequently 
are somewhat less conspicuous and a little farther apart. The riblets 
are nearly straight on the periphery of the whorls, but are somewhat 
angularly bent at the shoulder, and run obliquely forward across the 
subsutural band to the suture; on the subsutural band they are dis- 
tinctly elevated, but rather thinner than elsewhere. By the crossing 
of these two sets of lines the surface is generally finely and regularly 
cancellated, except on the shoulder and subsutural band, where the 
cancellation becomes more or less irregular or indistinct. Aperture 
rather large, broad-ovate, a little angulated at the shoulder, and with 
avery slight constriction at the base of the very short and rather 
narrow canal. The posterior sinus is nearly obsolete, and indicated 
only by a shallow indentation just above the shoulder. Columella 
short, straight, its inner margin with a rather strong sigmoid curv- 
ature. The canal is nearly straight, very slightly recurved at the 
tip, narrowed by a slight constriction of the outer lip, at its base. 
Epidermis thin, not very distinct. Color of the fresh alcoholic speci- 
mens pale grayish or greenish white, more or less translucent.

Gymnobela curta, var. subangulata Verrill, nov. 
Similar in form and size to the preceding, with which it is often 
associated. It differs in having the whorls more distinctly angulated 
at the shoulder, with one of the cinguli forming a distinct carina, 
which is surmounted by a row of small, often acute nodules, produced 
by the intersection of the longitudinal riblets. There is often another 
somewhat smaller spiral line below the carina, which also frequently
