evenly, finely, spirally, sharply striated; the intersections at the ribs of the major 
spirals are distinctly nodulous, the same sculpture is continued on to the canal, 
but there is crowded and less coarse; on the spire there are three or four spiral 
ridges crossing the ribs, and one or two well marked cords close to and in front 
of the suture; there are nine whorls beside the (lost) nucleus; aperture nar- 
rower, anal sulcus narrow, sharply defined, but not very deep; pillar straight, 
with a thin, smooth, callous surface; outer lip thin, very little produced ; canal 
short, wide, slightly recurved. Length of shell, 30.0; of aperture, 13.5; max. 
diam. 8.0 mm.

Turris (Surcula) resina Dat, n. sp. 
Shell (decollate) moderately large, slender, fusiform, solid, the spire longer than 
the aperture; shell with a broad, somewhat constricted anal fasciole and closely 
appressed suture, the fasciole chiefly sculptured by incremental lines; whorls with 
an angle at the shoulder where terminate (on the penultimate whorl twenty) 
straight, somewhat protractive, low, narrow, rather sharp axial ribs, which extend 
forward on the last whorl nearly to the base ; incremental lines rather prominent ; 
spiral sculpture of a few faint striae on the fasciole, between the fasciole and the 
next suture on the spire of five or six strap-like ridges with narrower interspaces 
often containing an obscure small intercalary thread, overriding the ribs without 
nodulation at the intersections; on the last whorl these ridges extend, somewhat 
diminishing in size, forward to the end of the canal, occasionally divided by a 
medial incised line, and with few intercalary threads, numbering about twenty-five 
in all; aperture narrow, outer lip defective, but by the lines of growth not much 
produced; anal suleus shallow, pronounced, the posterior angle of the aperture 
produced, much thickened and recurved; pillar straight, smooth, callous, axis 
impervious; canal straight, rather wide; interior of outer lip smooth; length of 
(decollate) shell, the last five whorls, 50; of the last whorl, 33; of the aperture, 
25; diameter at the posterior angle of the aperture, 17 mm.

bottom temperature 46° F. U.S. N. Mus. 123,108. 
This species has such a striking appearance that, although the unique specimen 
is defective, it could not fail to be recognized if found again. 
A large shell very much broken and eroded with a somewhat similar form and 
sculpture, but smoother, the spirals fainter and the ribs rounder and less numer- 
ous, was dredged at station 3370, in 134 fathoms, near Cocos Island. It has a 
large amorphous mass of callus on the proximal end of the pillar, but which does 
not extend inward beyond the first half whorl, and may be a pathological feature. 
There are parts of about six whorls remaining, about 58 mm. in length and 17 in 
maximum diameter. It is too imperfect to name, but is different from any other 
species obtained.
