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 whorls 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 and broader than the raised lines ; 
both the cinguli and interspaces are crossed by crowded, thin, raised 
lines of growth, along which the epidermis rises into small, short 
hairs, or thin seales. Aperture ovate, rather broad, slightly angu- 
lated 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 
white. Epidermis pale greenish yellow.
