Description.—Conical, apical angle about 60°, rounded not acute; height and width about equal; whorls five, with a nearly circular section, uniformly ventricose; suture distinct; umbilicus small, deep, one sixth the width of the base of the shell; the body whorl obtusely carinated close to the edge of the umbilicus ; the aperture nearly circular, its height slightly exceeding the width. Surface with obscure lines of growth, which cross the whorl a little obliquely from the suture downwards and backwards; a few wide shallow undulations parallel with the lines of growth. Height seven lines ; width the same ; width of aperture three lines, height three and a half. Locality and Formation.—Pauquettes Rapids, River Ottawa, Black River, and Birdseye. Collector.—Sir W. E. Logan. Straparollus asperostriatus. N. s. Description.—Shell small, depressed-conical; apical angle be- tween 80° and 90°; whorls about three with a nearly circular section, regularly ventricose above; obscurely carinated along the middle on the underside, suture distinct, umbilicus about one fourth the width of the shell, penetrating to the apex; aperture circular. Surface with strong sharply elevated lines of growth,. Please note that these images are extracted from scanned page images that may have been digitally enhanced for
