Margarita pupilla Carpenter (1863), p. 653; Pilsbry (1889), p. 295, pl. 44, 
figs. 29-32; Arnold, R. (1903), p. 333, pl. 10, fig. 15. 
Description—Arnold (1903) described this species as follows: 
‘Shell small, ovate-conic, rather solid; whorls five, convex, flattened slightly 
above, forming a narrow, tabulate band just below suture; body-whorl obtusely 
angulated; surface sculptured with small, flattened, subequal, equidistant, 
revolving ribs, five on the upper whorls; interspaces ornamented by fine, oblique, 
incremental lines; base of body-whorl nearly flat, and ornamented with num- 
erous fine, revolving lines, which become coarser near umbilicus; suture deeply 
impressed, distinct, aperture circular; columella somewhat arcuate; umbilicus 
small, groove-like; outer lip sharp, nacreous layer on inner lip.’’ 
Height, 3 mm. 
Occurrence.—At stations D 5773 (1). 
This shell is listed by Carpenter (1863) from the Farallon Islands. 
The only specimen in the Survey collections was dredged alive near 
Lime Point within the Golden Gate in 3 fathoms from a stony bottom. 
Range.—Alaska to Catalina Islands, California (Cooper).

Melanella Bowdich* 
Melanella (Eulima) micans (Carpenter) 
Plate 36, figure 11 
Eulima micans Carpenter (1863), p. 659; (1865a), p. 63; Tryon (1886c), 
p. 272, pl. 64, figs. 29, 30; Arnold, R. (1903), p. 269, pl. 9, fig. 12. 
Description.—Tryon (1886) described this species as follows: 
“Straight, white, semipellucid, shining; whorls flattened, the last oblong 
oval; aperture narrowly oval, outer lip somewhat straight and scarcely 
thickened.’” 
Height, 6 to 8 mm. 
Occurrence.—At stations D 5785 (1), D 5788* (7), D 5789 (3). 
This small gastropod is not mentioned in the lists of species from 
the vicinity of San Francisco. It is apparently restricted in distribu- 
tion to the open oceanic waters. Living specimens were obtained by 
the Survey in the vicinity of the Farallon Islands from depths rang- 
ing from 39 to 68 fathoms, the bottoms being composed of fine dark 
green sand. 
Range.—British Columbia to San Diego, California (Keep).
