Menetus dilatatus is a species of small air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Planorbidae, the ram's horn snails.
The shell is small, of a yellowish green-color, minutely wrinkled by the lines of growth. The spire is flat, [1] composed of 2.5-3 whorls, [2] separated by a well-defined suture. The outer whorl has a sharp margin on a level with the spire, diminishing near, but still modifying, the aperture. Below this line the whorl is very convexly rounded so as to encircle a small, deep, abruptly formed umbilicus. This whorl rapidly enlarges, and terminates in a very large, not very oblique aperture, with the lip expanded so as to make it trumpet-shaped. [1]
The width of the shell is 2–3 mm. [2] The height of the shell is 0.9 mm. [2]
The species is native to North America. The type locality is Nantucket island and Hingham, Massachusetts, USA. [1]
