eveuly, finely, spirally, sharply striated ; the intersectious 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 tliin, 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 Dall, 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 iacised 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 sulcus 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 nnn.

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 mucli 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 tlie pillar, but which does 

 not extend inward beyond tlie first half whorl, and may be a patliological 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 difl'ercut from any other 

 species obtained.
