BARTSCH: NEW ENGLAND PYRAMIDELLIDAE. 85 
riphery of the last whorl well rounded, marked only by the feeble ex- 
tensions of the axial ribs. Base somewhat inflated, well rounded, 
marked by the vanishing ribs and nine equally strong spiral striations, 
which are much finer than the incised lines on the spire and are spaced 
successively narrower from the periphery to the umbilical area. Aper- 
ture large, broadly oval, somewhat effuse at the junction of the outer 
and the basal lip; posterior angle obtuse, columella moderately stout, 
slightly curved, and reflexed. 
The specimen described and figured is the type, cat. no. 203,224 
U. S. N. M.; it comes from Vineyard Sound, Mass. It has nine post- 
nuclear whorls and measures: length, 5.3 mm.; diameter, 1.6 mm.

PI. 12, fig. 27. 
Shell stout, pupiform, bluish white with reddish yellow spiral stri- 
ations (nuclear whorls decollated; in the type the first post-nuclear 
turn is also lost). Post-nuclear whorls strongly rounded, weakly 
shouldered at the summit, crossed by strong, low rounded axial ribs 
of which there are about 18 upon the 3d, 4th, and oth of the remaining 
whorls; 20 upon the 6th; 22 upon the 7th; and 24 upon the penulti- 
mate turn. The spiral sculpture consists of five strongly impressed 
lines, grouped in series, the first and second above the periphery being 
as far apart as the third and fourth, while the space between the second 
and third is about one and one half times as wide. The space between 
the fourth and fifth equals that between the second and third. In 
addition to these strong lines there are three very fine lines on the 
shoulder of the whorl between the fifth spiral and the summit. Pe- 
riphery of the last whorl smooth excepting the continuations of the 
axial ribs. Base moderately long, well rounded, marked by the feeble 
extensions of the ribs and twelve more or less wavy spiral lines of which 
the one immediately below the periphery is the strongest, the rest
