U.S. S. “Albatross,” station 3376, off the Heuador coast, in 1132 fathoms, 
ooze, bottom temperature 36°.3 F. U.S. N. Mus. 125,964. Also at station 
3375, south of Malpelo Island, Gulf of Panama, in 1201 fathoms, ooze, tempera- 
ture 36°.6; and station 3366, off Cocos Island, in 1067 fathoms, ooze, tempera- 
ture 37° F. A fragment, taken off Mazatlan, at station 3421, in 995 fathoms, 
mud, may possibly belong to this species. 
GANESA JEFFREYS. 
? Ganesa panamensis Datt. 
Plate 19, figure 4. 
Ganesa? panamensis Dall, Proc. U. S. Nat. Mus., 1902, 24, p. 554. 
Shell small, turbinate, smooth, whitish with a few grayish flecks and streaks 
which may not be normal to the shell, and about three and a half turgid whorls ; 
nucleus eroded, apparently large and subglobular; subsequent whorls polished, 
smooth except for faint incremental lines, and a line at the anterior edge of the 
suture, caused by the appression of the edge of the whorl but which looks like a 
spiral thread ; on the base around avery small, oblique, chink-like umbilicus there 
are spiral striae, much as in Molleria, to the number of twelve to fifteen; base 
rounded; aperture nearly rounded, slightly angular at the posterior commissure ; 
outer lip sharp, thin, simple; a thin wash of callus on the body; pillar-lip con- 
cavely arcuate, slightly thickened, passing imperceptibly into the anterior margin 
of the aperture ; throat slightly pearly, smooth, without liration or opercular ledge 
such as is found in Molleria. Operculum horny, thin, smooth outside, concave, 
with about four whorls. Alt. of shell, 4.7; of last whorl, 4.3; of aperture, 3.2; 
max. diam. of base, 4.5 mm. 
U.S. 8. “ Albatross,” station 3393, in 1020 fathoms, mud; Gulf of Panama, 
bottom temperature 36°.8 F. U.S. N. Mus. 109,029. 
The position of Ganesa Jeffreys is more or less uncertain, but the present shell, 
though larger, resembles in general the species which Jeffreys included in his 
group; and there seems to be no other group defined into which this little shell 
would fit more appropriately.
