[81] ALBATROSS EXPLORATIONS. 583 
rounded, very conspicuous cinguli, which, in crossing the ribs, form 
prominent, smooth, white, oblong beads or nodules; there are three 
rows of these on the whorls of the spire, and five or six on the body- 
whorl, the second and third below the suture being more prominent and 
farther apart than the others. Cinguli without nodules continue to the 
end of the canal, the transverse ribs disappearing atits base. Aperture 
a little more than one-third the length of the shell, narrow-ovate, pinched 
up anteriorly into a very narrow, short canal; outer lip thickened, form- 
ing a slight varix, with a thin, white edge and a shallow sinus, close to 
the suture, with one or two minute white crenulations just within its 
posterior edge; there are also about five similar but much larger crenu- 
lations on the inner margin of the lip, extending from the sinus to the 
base of the canal. Inner lip continuous with the outer, with a free, 
thin, white edge, having four or five minute white crenulations just 
within its inner margin. Canal short, narrow, bent slightly backward 
at its anterior end, with a decided, but shallow, notch. 
Color of dead specimens, in alcohol, light brown; when dry, dirty 
white. One fresh specimen has a light brown, lamellose epidermis. It 
may belong to Pisania. 
Length of a specimen with imperfect nucleus, 5™™; its breadth, 2.5™™; 
length of aperture, 2.5™™; its breadth, 1™™. 
Three imperfect specimens, (No. 35,363) were taken at station 2,108.
