Carquinez Strait, in the middle and lower division of the bay as well 
as in the vicinity of the Farallon Islands. Living specimens were 
taken along the shore at several localities and at depths ranging up 
to 68 fathoms. This species occurs most frequently upon a bottom 
that may be characterized as muddy sand. 
Range.—Alaska to San Diego, California (Cooper).

Description.—This species was described by Arnold (1903) as follows: 
““Shell small, solid, fusiform; spire elevated; apex acute; whorls seven, 
slightly convex, with about eighteen to twenty rather wavy, slightly oblique, 
rounded, transverse ridges extending from suture to suture; spiral ornamenta- 
tion consists of numerous fine raised lines in the interspaces between the trans- 
verse ridges; suture impressed, distinct aperture rhomboidal, narrow; outer lip 
lirate within; inner lip incrusted, smooth; canal short, recurved; pillar spirally 
lined externally.’’ 
Carpenter (1863) reported this species from this region. Ob- 
tained from a depth of 40 fathoms. Not obtained by the Survey. 
Range.—Sitka, Alaska, to Monterey, California (Tryon).

Wood and Raymond (1891) report the tropical species C. gem- 
matus Reeve from these local waters. It is probable that those authors 
confused Reeve’s species with some other similar form.
