“Shell sinistral, elongate sub-fusiform, apex acute, sometimes slightly bent, 
nuclear whorls two, very convex, loosely twisted and white; whorls eleven or 
twelve, slightly convex; color a reddish brown, somewhat lighter on the middle 
of the whorl; aperture narrow, canal short, inner lip moderately encrusted with 
a white callus, brown on the outer margin; columella twisted; outer lip acute, 
sinus rounded, shallow, broad and adjoining the suture.’’ 
Height, 20 to 40 mm. 
Occurrence—At stations D 5785* (1), D 5790 (1). 
According to Carpenter, this region falls within the range of this 
species, but it appears not to have been reported from the vicinity of 
San Francisco. It is represented in the Survey collections by two 
specimens from the open ocean, dredged at depths of 33 and 39 fathoms 
from a sandy bottom. 
Range—Vancouver Island, B. C. (Cooper), to Lower California 
(Dall). 
Turris (Bela) tabulata (Carpenter) 
Plate 39, figure 1 
Mangelia tabulata Carpenter (1863), p. 658. 
Description.—Carpenter described this species as follows: 
*«Stout, strongly shouldered, coarsely cancellated. Pillar abnormally twisted.’’ 
Height, 3 to 11 mm. 
Occurrence.—At stations D 5785 (1), D 5786 (5), D5788* (2, 2). 
This species was dredged by the Survey only in the vicinity of the 
Farallon Islands. Living specimens were obtained from a sandy 
bottom at a depth of 68 fathoms. 
Range.—Vaneouver Island to Todos Santos Bay, Lower California.

pl. 1, fig. 8; Dall (1909), p. 27, pl. 4, fig. 8. 
Description.—Dall described this species as follows: 
‘«Shell ovate-fusiform, solid, of five or more whorls; seulpture chiefly with 
fine close-set spiral threads subequal in size, with linear interspaces, and almost 
obsolete above the shoulder; whorls moderately convex, above the rounded 
shoulder moderately excavated with a closely appressed suture; axial sculpture 
of rather inconspicuous incremental lines, most evident between the suture and 
the shoulder, where they are concavely arcuate in harmony with the wide, 
shallow anal sinus; aperture ovate-elongate, with a short canal and smooth 
pillar often obscurely thickened mesially.’’ 
Height, 17 to 75 mm. 
Occurrence.—At stations D 5785* (1), D5787 (1), D 5788 (1), 
D 5789) (15, 2), D'5792 (1).
