rated by intervals of about the same width; these extend over the 
subsutural band, but are there a little less prominent ; on the convex 
part of the whorls they are wavy and irregularly decussated bythe 
lines of growth; on the spire the two sets of lines produce a cancel- 
lated structure. The aperture is short and rather broad,*with an 
acute angle posteriorly and a short, broad, straight canal in front; 
the columella is short, nearly straight, with the inner edge strongly 
sinuous and obliquely cut away at the end. The inner lip is strongly 
excavated at the base of the columella; the outer lip ‘is regularly 
curved, except above the shoulder, where it is slightly! flattened and 
sloping; in the middle it projects considerably forward in a broad 
curve, but the posterior sinus is broad, rather deep, well-rounded, and 
deepest just above the shoulder. 
Color, grayish or yellowish white externally, bluish white within ; 
in one specimen with a conspicuous reddish brown patch on the col- 
umella margin. 
Length, 22™; greatest breadth, 10"; length of body-whorl, in 
front, 15"; length of aperture, 11™"; breadth of aperture, 5™™. 
Two living specimens (No. 44,653), were taken at station 2,208, in 
1,178 fathoms, N. lat. 39° 33'; W. long. 71° 16’ 15”. 
This species is named in honor of Mr. Herman Friele, the able 
conchologist of the Norwegian Arctic expeditions.

PLATE XLIV, FIGURE 6. 
Shell small, thin, delicate, translucent bluish white, rather stout, 
fusiform, with angular whorls and an acute spire. Whorls four and 
one-half, besides the nucleus, which is small, acute and consists of 
about three chestnut-brown whorls. The whorls of the spire are 
angulated and somewhat carinated at about the middle, where there 
is a band of angular tubercles. The subsutural band is broad, slop 
ing, flattened or sometimes distinctly concave, and occupies more 
than half the breadth of the whorls. 
The sculpture consists of about twelve to fourteen oblique, some- 
what angular and prominent transverse ribs, separated by broader, 
concave intervals, rising at the shoulder into small angular tuber- 
cles, on the subsutural band becoming much smaller and strongly 
excurved in the middle, like the lines of growth, and rising into 
small, sharp lamellee just below the suture. The surface is also 
covered with very distinct, raised, revolving cinguli, separated by
