guli, which foiin as many rows of small acute nodules in crossing the 

 ribs; these are similar to those on tlie carina of the shoulder, hut 

 usually a little smaller. There is commonly another row of smaller 

 tubercles of the same kind just above the shoulder. On the last 

 whorl there are from fifteen to eighteen cinguli, which are unequal in 

 size and decrease in prominence from the carina to the base of the 

 canal; most of these form small, sharp nodules in crossing the ribs. 

 The ribs are a little prominent, rather oblique, sharp at summit, 

 and separated by concave interspaces of somewhat greater width ; 

 on the upper whorls they run from just above the shoulder forward 

 to the suture ; on the body-whorl they curve strongly forward in the 

 middle and then recede and disappear before reaching the base of the 

 canal. The subsutural band is very wide, strongly sloping, and 

 somewhat concave just above the shoulder; it is covered with numer- 

 ous, rather conspicuous, thin, raised riblets, which are strongly ex- 

 curved in the middle and bend forward before reaching the suture. 

 Two or sometimes three cinguli exist on the subsutural band ; the 

 uppermost of these is just below the suture and forms there a small 

 carina, above which the suture is distinctly channeled. The surface 

 between the ribs is everywhere covered by fine, distinct, flexuous 

 lines of growth. The aperture is long-ovate, rather narrow, angu- 

 lated externally ; the outer lip is thin and sharp, with a broad, rounded 

 posterior sinus, just above the shoulder and a little removed from the 

 suture ; below the shoulder the lip arches forward in a broad curve, 

 and becomes incurved at the base of the canal, which is rather con. 

 tracted and a little bent to the right and slightly everted at tip. 

 Columella short and nearly straight, its inner edge forming a strong 

 sigmoid curvature. Epidermis indistinct. Color white, with the 

 exception of the light yellowish brown nucleus.

This species bears considerable resemblance to several others of 

 the same group, but difiers very decidedly from all the rest in the 

 character of the nucleus, which is remarkable for its relatively large
