Plate I. Figs. 3, 4. 
One living specimen, Station 319, off Charleston, S. ©., in 262 fathoms. 
Shell small, fusiform, rather thin, of a light yellow color. Whorls six, evenly 
and moderately rounded, ornamented with three high, thin foliaceous varices 
and covered with coarse revolving threads and microscopic strip. Aperture 
nearly round, with a long, curved, tubular canal, and a smooth, lustrous inte- 
rior, Outer lip with a slightly thickened edge, descending a little obliquely 
from the suture, forming a slight obtuse posterior angle, below which it is 
somewhat flaring and curves well round to the base of the canal, where there 
is another slight angle, then curves gradually outward to the end of the canal. 
Inner lip formed by a rather narrow, thin, lustrous layer of enamel closely ad- 
hering to the body whorl to just above the base of the canal, where it becomes 
detached and twists forward and over to meet the outer lip, nearly or quite 
1 Mr. Dall, in this Bulletin, XVIII. p. 174, 1889, suggests that this species is the 
same as Sipho Bocagei Fischer, but gives no reference to description or figure. 
In the limited number of Mr. Fischer's papers at my command, I have been unable 
to find such a species, and therefore can express no opinion on the subject.
