BARTSCH: NEW ENGLAND PYRAMIDELLIDAE. 101 
at the summit, marked by fine, irregular, obsolete axial riblets which 
are strongest near the summit of the whorls, and many fine spiral 
lirations about five of which are a little coarser than the rest, between 
the sutures. Periphery and base of the last whorl well rounded, the 
latter weakly umbilicated and marked by lines of growth and fine 
spiral lirations. Aperture oval; posterior angle obtuse; outer lip 
thin, showing the external marking within; columella very slender, 
strongly curved and slightly reflexed, provided with a weak internal 
fold. 
The type and one other specimen, cat. no. 203,797 U. S. N. M., 
were collected by Rev. H. W. Winkley at Branford, Conn. The tyjDC 
has six post-nuclear whorls and measures: length, 2.8 mm.; diameter, 
1.3 mm. Four additional specimens from the same locality are in 
Rev. Winkley's collection.

PI. 13, fig. 43. 
Shell thin, elongate-ovate, shining, white, broadly umbilicated. 
Nuclear whorls very small, obliquely completely immersed in the 
first of the succeeding turns, which gives the spire a truncated appear- 
ance. Post-nuclear whorls inflated, strongly rounded, anterior half 
between the sutures marked by about ten slender spiral grooves ; 
posterior half smooth, excepting many exceedingly fine microscopic 
spiral lines. Periphery and base of the last whorl inflated, well 
rounded, the latter marked by about four incised spirals immediately 
anterior to the periphery, which agree with those between the sutures 
in strength and spacing. The rest of the base is smooth. The axial 
threads which usually cross the spiral grooves in species of this sub- 
genus are here reduced to mere fine lines. Base widely umbilicated.
