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 ai-e usually of nearly the same size as the cinguli, but frequently 

 are somewhat less conspicuous and a little farther apart. The riblets 

 are nearly straiglit on the peripliery of the vvhorls, 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, Avbere the 

 cancellation becomes more or less irregular or indistinct. Aperture 

 rather large, broad-ovate, a little angulated at the shoulder, and with 

 a very 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 giayish or greenish white, more or less translucent.

Gymnobela curta, var. subangulata Verriii, 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 cingidi forming a distinct carina, 

 which is sitrmounted by a row of small, often acute nodules, produced 

 by the intersection of the longittidinal riblets. There is often another 

 somewhat smaller spiral line below the carina, which also freqtiently
