with subparallel sides ; aperture open ; lip-edge semicircular, with 

 the hind angle incurved, produced and acute. (Ad.*).

P. acutangula AD. Ann. Mag. (3), ix, p. 161. 



The nearest approach to this species is P. scutulum Loven ; 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 SOWB., C. Icon, xviii, pi. 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. (Sowb.~). 



P. JAPONICA 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-
