Sipho profundicola, var. dispar, nov. 



Shell of medium size, stout-fusiform, with very convex, rounded 

 whorls, the upper ones with both transverse ribs and spiral lines; 

 the lower ones with spiral lines only. Whorls about six, besides the 

 nucleus, which is eroded. They are slightly shouldered and some- 

 what turreted and increase rapidly in size. The upper ones have 

 stout, raised spiral lines or cinguli, of unequal size, and mostly 

 acute at summit, separated by wider, concave interspaces ; they are 

 also crossed by many rather feebly marked transverse ridges, most 

 distinct at the shoulder ; these disappear on the lower whorls, on 

 which there are numerous, conspicuous, unequal, mostly strongly 

 raised, spiral lines, which cover the whole surface. One of these, 

 considerably larger than the rest, forms the angle of the shoulder; 

 above this the whoi'ls descend somewhat abruptly to the suture, but 

 with a convex outline ; just below the angle the whorls are a little 

 flattened and then are convexly rounded. The more prominent of 

 the cinguli are somewhat thickened and obtusely rounded ; between 

 these there are from three to five smaller and thinner ones. The 

 interspaces are strongly concave aud broader than the raised lines ; 

 both the cinguli and interspaces are crossed l)y crowded, thin, raised 

 lines of growth, along which the epidermis rises into small, short 

 hairs, or thin scales. Aperture ovate, rather broad, slightly angu- 

 hited at the shoulder. Canal moderately long, rather narrow, some- 

 what bent to the left, and slightly turned up at the end. Columella 

 strongly sinuous, with the inner margin sharp and decidedly twisted 

 along the margin of the canal. Body-whorl decidedly excavated 

 along the inner lip. Operculum broad-elliptical, with the nucleus at 

 the anterior edge, yellowish horn-color. Shell internally bluish 

 while. Epidermis pale greenish yellow.
