Streptaxis is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Streptaxidae. [2] [3]
The oval shell has a heliciform shape, but is often oblique. It is profoundly umbilicated, ridged, striate above, smooth and usually polished below. The last whorls are usually deviating more or less from the original axis. The aperture is lunar, with or without teeth. The outer lip slightly thickened and reflected.
The animal has a very long neck and short tail. The superior tentacles are narrow and long. The labial palpi are narrow, as long as the inferior tentacles. The genital orifice is on the right side, distant from the superior tentacle, and closer to the respiratory orifice. The radula is similar to that of Glandina; the central tooth is simple. [4]
