"Shell solid, subcylindrical, tapering above with summit pointed. Body-whorl almost twice as high as spire. The callus not only covers the spire, but on the back side of the shell also covers the upper portion of the body-whorl, occasionally sending long narrow processes down to the spiral sulcus, while on the front side it comes down to the sulcus as a broad belt covering the upper part of the inner lip. On this account the suture separating the body-whorl from the spire is hidden for two-thirds of its length under the callus. Spiral sulcus broad, with a deep oblique valley below, followed by several spiral folds. Aperture long, pointed above. Canal very short, notched behind. The only specimen we possess is 25 millim. in height and 9 millim. in diameter. The apertural length is 13 13 millim., while the height of the spire is 8.5 millim.'". Pliocene. Shimomata, Shizuoka Prefecture, Japan.
The holotype UMUT CM 23364 appears to be missing (Ichikawa, 1983).
