BARTSCH: NEW ENGLAND PYRAMIDELLIDAE. 83 
feebly incised wavy spiral strialions. Aperture subquadrate, posterior 
angle obtuse; outer lip thin, showing the external sculpture within, 
forming a broad angle with the equally thin basal wall; columella 
slender, not curved, obliquely placed, and slightly re volute. 
The type, cat. no. 94,826a U. S. N. M., comes from Martha's Vine- 
yard, Mass. It has nine post-nuclear whorls and measures: length, 
4.9 mm.; diameter, 1.4 mm. 
This species is named in honor of Professor A. E. Verrill, the eminent 
zoologist at Yale university. 
Turbonilla (Pyrgiscus) vineae new species. 
PI. 12, figs. 22, 36. 
Shell elongate- conic, wax yellow. Nuclear whorls very small, 
two, depressed helicoid, having their axis at a right angle to that of the 
succeeding turns. Early post-nuclear whorls well rounded, later ones 
flattened in the middle, rounding rapidly toward the sutures. The 
whorls are ornamented by moderately strong, broad, low, retractive 
axial ribs which become somewhat flattened and less strong as they 
approach the summit; of these there are about 22 upon all but the 
penultimate turn, on the latter there are 25. Intercostal spaces about 
as wide as the ribs, marked between the sutures by fine lines of growth 
and seven or eight deeply incised spiral lines of pits. The faint shoul- 
dering of the later turns lends the sutures a somewhat constricted 
appearance. Periphery of the last turn well rounded, marked by a 
smooth spiral band (excepting the weak continuations of the axial ribs 
which cross it). Base short, somewhat inflated and well rounded, 
crossed by the feeble continuations of the axial ribs which vanish 
before reaching the umbilical area, fine incremental lines, and about 
eight, fine, wavy spiral striations, of which those nearest the periphery 
are the strongest and the rest successively weaker. Aperture large, 
irregularly ovate, somewhat effuse at the junction of the lateral and 
basal lip; outer lip thin, showing the external sculpture within; 
columella slender, slightly curved, and revolute. 
The above description is a composite one, taken from two individuals. 
The nucleus and the early turns are described from a young individual, 
cat. no. 203,757 U. S. N. M., while cat. no. 203,756 U. S. N. M., which 
is an adult having the last nine whorls (the first two probably, and 
the nucleus being lost) has furnished the remainder of our diagnosis.
