BARTSCH: NEW ENGLAND PYRAMIDELLIDAE. 103 
"^ a rounded shoulder close to the suture, the portion next the suture 
rising aljru])tl_v, nearly at a right angle; periphery flattened, or very 
slightly round(>d; suture little oblique, impressed, or subcanaliculate. 
Aj)erture narrowly contracted posteriorly, narrow-ovate anteriorly; 
outer li]) little convex, slightly produced anteriorly; columella excurved, 
flattened, with no fold nor tooth. Sculpture delicate, incised, spiral 
grooves, separated by wider intervals, and covering the anterior two- 
thirds of the body-whorl, extending a little back of the aperture, but 
mostly absent on the preceding whorls. No umbilicus. Length, 5 
mm.; breadth, 2.5 mm.; length of body-whorl, 3.5 mm.; of aperture, 
2.5 mm.; its breadth, 1 mm. 
"Off Newport, R. I., station 892, in 487 fathoms, 1880. 
"I have named this species in honor of Mr. H. L. Bruner, an 
assistant in the conchological work of the Fish Commission during the 
season of 1881." 
We have not seen this species and have quoted Verrill's original 
statement.

Turritella impressa Say, Journ. acad. nat. sci. Phila., vol. 2, p. 244, 1821. 
Shell elongate- conic, milk white. Nuclear whorls small, about 
half obliquely immersed in the first of the succeeding turns. Post- 
nuclear whorls flattened, shouldered at the summit, marked by three, 
strong, deeply incised spiral grooves, which almost equal the spaces 
that separate them in width. Grooves crossed by numerous fine 
axial threads. The spaces between the spiral grooves are rounded 
on the sides and obliquely flattened at the top, marked only by incre- 
mental lines. Sutures channelled, the first basal cord usually showing 
in it the last three volutions. Periphery marked by a deep channel, 
like those above it. Base somewhat produced, well rounded, rqarked 
like the spaces between the sutures by seven spiral grooves which are 
of almost equal strength and spacing, but less strong than those on 
the spire. Aperture elongate-ovate, somewhat effuse anteriorly, 
posterior angle acute; outer lip thin, slightly sinuous at the edge, 
showing the external sculpture within; columella very stout, re- 
enforced by the attenuated base, provided wdth a strong oblique fold 
at the insertion; parietal wall covered by a thin callus.
