==Description== The shell is 5 to 8 millimeters widea and red-brown in colour. It is fragile, short, turreted, and conical with large body whorl, three whorls and an almost circular aperture. The aperture is about 50% of the shell height, the spire is very short and the whorls are convex with deep sutures. Surface moderately shiny with relatively coarse growth lines. In life the dark digestive gland shows through the spire making it seem very dark compared to the body whorl. The animal is dark grey to black. The shell is very similar to Succinella oblonga. Identification requires dissection. The genitalia differ in these respects: "Penis short with a black spot at vas deferens and retractor insertion, vas deferens inserts directly into penis, epiphallus absent, penis without envelope (S. oblonga has a long penis with epiphallus and a long vas deferens)."
