Wood and Raymond recognized this species within the limits of 
San Francisco County. It was not found among the Survey specimens. 
These authors also list the eastern form LH. groenlandica Perry. 
Range. —San Francisco (Wood and Raymond) to San Diego 
(Cooper). 
Epitonium hindsi (Carpenter) 
Plate 36, figures 14a and 14b 
Scalaria hindsi Carpenter (1856c), p. 165. 
Scala hindsi, Arnold, R. (1903), p. 364. 
Description.—Arnold (1903) described this species as follows: 
“‘Shell small, turreted, thin; whorls eight, evenly convex; varices eight to 
twelve, sharp, thin, sometimes reflexed, very prominently coronated just anterior 
to suture; suture deep, distinct; aperture subcireular; lip slightly thickened; 
inner lip slightly inerusted.’’ 
Height, 5 to 10 mm. 
Occurrence.—At stations D 5712 (1), D 5724 B (2), D5833 (128), 
fishing grounds west of Golden Gate* (1), west of Farallon Islands 
(1). 
This southern species has not hitherto been reported from these 
local waters. It is sparingly represented among the Survey collections 
at stations within the bay and outside the Golden Gate. Living speci- 
mens are recorded from depths ranging from 884 to 815 fathoms, on 
bottoms which are predominantly sandy. 
Range.—Bodega Bay, California to Panama (Orcutt). 
Epitonium sawinae (Dall) 
Plate 36, figure 13 
Scala sawinae Dall (1903b), p. 175. 
Description.—This species was originally described as follows: 
‘‘Shell small, elongate, sub-acute, with ten or more whorls; nucleus of 
three smooth polished whorls; subsequent whorls smooth, with about 19 low, 
sharp, slightly reflected varices which entirely cross the whorl; at the shoulder 
these are slightly spinose; aperture rounded ovate, entire, with a small spine at 
the shoulder angle and a less conspicuous one at the inner base of the aperture; 
there is no trace of a basal cord or disk, and no spiral sculpture. Length, 
10.5; diameter of aperture, 2.5; max. diameter of last whorl, 4.0 mm. A broken 
specimen with three more whorls seems to have measured 24 mm. in total length 
when perfect, and 8 mm. in diameter.’’ 
Height, 3 to 16 mm. 
Occurrence.—At stations D 5785* (217, 6), D5786 (10), D 5787 
(2), D 5788 (8), D 5789 (7, 11), D 5790 (3), D 5833 (1).
