NEW SPECIES OF MOLLUSKS 
143 
Odostomia (Eyalea) cypeia, new species. 
Plate X, fig. 4. 
Shell of medium size, narrowly elongate-ovate, umbilicated, 
yellowish white (Nuclear whorls decollated.) Post-nuclear 
whorls rather high between the sutures, moderately rounded, 
very feebly shouldered at the summit, marked by fine lines of 
growth and numerous exceedingly fine, closely-spaced, spiral 
striations. Sutures very slightly constricted. Periphery of the 
last whorl very rounded. Base moderately long, well-rounded, 
narrowly umbilicated. Aperture broadly oval, effuse anteriorly; 
posterior angle obtuse; outer lip thin; inner lip oblique in front, 
slightly curved and reflected, with the margin free, provided 
with a very deep-seated feeble fold at its insertion; parietal 
wall covered with a thick callus, which renders the peritreme 
complete. 
The unique type, which was dredged by Mr. Spreadborough 
at Bkidegate, is in the collection of the Dominion Geological 
Survey. It has five post-nuclear whorls and measures: length 
4 mm., diameter 2 mm. 
Odostomia (Evalea) hypatia, new species. 
Plate X, fig. 5. 
Shell large, elongate-ovate, strongly umbilicated, yellowish 
white. Nuclear whorls deeply immersed in the first of the 
succeeding turns, above which only the tilted edge of the last 
volution projects. Post-nuclear whorls well-rounded, feebly 
shouldered at the summit, marked by fine incremental lines 
and numerous exceedingly fine, closely-spaced, spiral striations. 
Sutures moderately constricted. Periphery of the last whorl 
inflated, well-rounded. Base moderately long, well-rounded, 
openly umbilicated. Aperture oval, effuse anteriorly. Pos- 
terior angle obtuse; outer lip thin; columella very oblique, 
slender, curved, and decidedly reflected, not reinforced by the 
base, provided with a moderately strong fold a little anterior 
to its insertion; parietal wall glazed with a thin callus.
