with subparallel sides ; aperture open; lip-edge semicircular, with 
the hind angle incurved, produced and acute. (Ad.).

P. acutangula Ap. Ann. Mag. (3), ix, p. 161. 
The nearest approach to this species is P. scutudum Lovén; but 
the produced sharp hind angle of the outer lip will serve readily to 
distinguish it. (Ad.). 
P. TRUNCATISSIMA Sowerby. PI. 2, figs. 19, 20. 
Shell short, subquadrate, subcompressed, thin, diaphanous, marked 
with distant concentric opaque lines which are angular in front; 
aperture very wide in front, widely truncated; outer lip angular. 
(Soub.). 
Habitat unknown. 
Philine truncatissima Sows., C. Icon. xviii, pl. 1, f. 5a, b. 
This transparent little species is remarkable for the truncated 
character of the widened anterior, producing an angle on the lower 
part of the outer lip; which is beautifully indicated by the opaque 
white lines delineating the edges of former outer lips. (Sowd.). 
P. saponica Lischke. Pl. 2, figs. 23, 24 (type); figs. 17, 18 
(striatella Tap.-Can., enlarged). 
Shell square-ovate, thin, milky or bluish-white, generally pellucid 
below; sculptured with irregular, low growth-wrinkles and close, 
fine spiral impressed lines, sometimes subobsolete below. Vertex 
narrow, rather deeply umbilicated, showing one whorl; body-whorl 
with a shallow, wide spiral depression in the middle and another 
above it. Aperture extremely large, broad, effuse and subtruncate 
below, deeply sinused above; outer lip prominent and obtusely 
angular at the junction of the lightly arcuate outer and basal mar- 
gins, produced in a widely rounded lobe above the vertex. Col- 
umella deeply and equably arched, margined by a slight groove.
