The specimen described and figured is one of four, cat. no. 94,847 
U. S. N. M., which were collected by Dr. Stimpson at New Bedford, 
Mass. It has eight post-nuclear whorls and measures: length, 4.8 
mm.; diameter, 1.6 mm. Another lot from Massachusetts Bay, 
cat. no. 94,848 U. S. N. M., was also collected by Dr. Stimpson.

"Shell small, white, long-ovate; spire regularly tapered, acute, 
whorls about six, moderately convex, covered with many, regular, 
rather strong, revohing grooves. Nuclear whorl strongly inflexed 
and reversed. Aperture regularly ovate. No tooth on the columella. 
Length 2.8 mm., of body-whorl 1.8 mm., breadth 1.4 mm., length of 
aperture 1.1 mm., its breadth 0.7 mm. 
"Stations 871 and 894, in 115 and 365 fathoms. 
"This differs from all other related species of our coast, except 
0. striatiila Couth. (= Menesilto albula Gould, non Fabr.) in being 
strongly grooved spirally; from the latter it differs in having fewer 
whorls and a regularly tapered acute spire, and in having the spiral 
lines coarser and fewer. Perhaps it is more closely related to the real 
Menestho albula of Greenland, which, according to Jeffreys, is distinct 
from our shell, so named by Gould. These three forms all belong to 
Menestho Moller ( = ,Liostomia G. O. Sars)." 
The above is Verrill's original diagnosis; we have not seen this 
species. 
Odostomia (Menestho) trifida (Totten). 
• PI. 13, fig. 46. 
Actaeon trifida Totten, Amer. journ. sci. and arts, vol. 26, p. 368, figs. 4a, 
4b, 1834, = Odostomia insculpta DeKay, Moll. N. Y., p. 115, pi. 31, fig. 297,

Shell elongate-ovate, shining white. Nuclear whorls small, almost 
completely obliquely immersed in the first of the succeeding turns.
