raised cinguli, or small carinze, more strongly marked than the others, 
and bearing each a series of small, rounded nodules where they are 
crossed by the stronger lines of growth ; sometimes these nodules are 
present only on the uppermost of these two carinw, which are sepa- 
rated by a narrow interspace. Below the carinz the whorl rapidly 
decreases in size, the anterior slope being nearly the same as the pos- 
terior one, and of about the same breadth on the spire; this portion 
of the whorl is crossed by three to five rather coarse, raised, irregular 
spiral lines, and numerous fine lines of growth, which bend abruptly 
forward at the shoulder and then curve obliquely downward and for- 
ward, crossing both the spiral lines and their interspaces, which are 
about the same in breadth. On the body-whorl the spiral lines cover 
the whole surface below the shoulder, becoming coarser and farther 
apart below the middle, and again becoming smaller and closer to- 
gether on the base of the siphon. Aperture narrow-ovate and some- 
what angulated by the shoulder. Outer lip sharp-edged, with a 
rather broad and deep pesterior sinus, which is deepest at the shoulder ; 
below the shoulder the lip projects forward in a broad even curve to 
near the base of the canal, where it is somewhat contracted. The 
canal is moderately long, somewhat contracted at the base, and a 
little sinuous. The columella has a strong sinuous curvature, and is 
strongly excavated at the widest part of the aperture. Upper whorls 
and nucleus eroded in our examples. Epidermis yellowish horn- 
color, closely adherent. Shell biuish white within the aperture. 
Operculum well-developed, ovate, dark horn-color. 
Length of the shell without the tip, 25™™ ; length of body-whorl 
to tip of canal, 17"; greatest breadth, 10™™; length of aperture, 
13°5™™; its breadth, 5°5™™. 
No. 35,237, station 2098, N. latitude 37° 40’ 30”, W. longitude 70° 
37’ 30", in 2221 fathoms. One living specimen with only the four 
lower whorls present. No. 35,220, station 2097, N. latitude 37° 56’ 
20”, W. longitude 70° 57’ 30”, in 1917 fathoms. Another similar 
specimen, but dead and much eroded.

Puats XXXI, FIGURE 8. 
Shell long-fusiform, with a high, turreted, regularly tapered, acute 
spire, all the whorls having, at some distance below the suture, a 
well-marked, angular shoulder, which is crowned by a series of 
oblique nodular riblets on all the whorls except the last.
