Proceedings of the United States National Museum, 53:326; PI. 41, fig. 6. 
Shell of moderate size, slender, with a double flexure. When viewed 
with the aperture to the front, it shows the early whorls bent backward 
and the succeeding turns flexed to the right. Shell bluish-white, except 
where the dried animal shines through its substance; there is has a granu¬ 
lar light-brown to buff appearance. First four whorls well-rounded, with 
well-impressed suture, the remainder almost flattened, marked by exceed¬ 
ingly fine lines of growth only, and separated by a scarcely visible suture. 
The posterior limit of the inside of the whorls shines through the substance 
of the shell and appears as a conspicuous false suture. Periphery of the 
last whorl weakly angulated. Base somewhat prolonged, well-rounded. 
Aperture long, ovate; posterior angle acute; outer lip considerably pro¬ 
tracted, particularly so at the periphery; inner lip stout, curved, reflected 
over and appressed to the base; parietal wall covered by a thick callus. 
Length, 7.5; diameter, 1.9 mm. (Bartsch.) 
Type in United States National Museum, No. 207772. Type locality, 
Departure Bay, British Columbia.

Plate 45, fig. 3 
Proceedings of the United States National Museum, 53:326; PI. 42, fig. 3. 
Shell elongate-conic, with a double flexure; the first bend when the 
specimen is viewed with the aperture to the front, is to the right, and the 
second flexure is backward. The clean shell is bluish-white, but when the 
animal has been allowed to dry in it, it appears brown. The first two turns 
well-rounded, separated by a constricted suture, the remainder flattened, 
marked by exceedingly fine lines of growth and very fine microscopic spiral 
striations. Sutures scarcely preceptible. The posterior limit of the inside 
of the whorls appears through the mass of the shell as a false suture. 
Periphery of the last whorl well-rounded. Base short, somewhat inflated
