Shell oblong-conic, or elongated oblong-conic, the body 

 being of a rather narrow truncated oval figure, and the 

 spire, when not decollated, tapering gradually to a small 

 point ; moderately strong for the genus, not particularly

 the microscopic sculpture as in stagnalis, and with the 

 meandering vein-like transverse elevations that are occa-

 tapering, and neither planulate nor abruptly tumid above, 

 divided by a profound and slanting suture : penult turn 

 filling about a fourth of the dorsal length. IJody as long
