According to research of Euconulus polygyratus, documented by Henry A. Pilsbry in 1946 , the following information,  should assist you with distinguishing this species from others.

The shell of Euconulus polygyratus is thin, imperforate (not porous), globosely conic, cinnamon buff, the surface somewhat dull and silky except the middle base, which is glossy and somewhat transparent.

The spire, which is the last few whorls of the shell, is rather dome-shaped, its outlines being strongly convex.

The whorls(coils or spirals), can help differentiate between species as well, and with Euconulus polygyratus, increase slowly and are strongly becoming rounded in those of full growth.

The aperture, which is the opening of the shell, is narrowly lunate , in other words, crescent shaped.

While researching, I was fortunate to find a couple nice photos of Euconulus polygyratus (Fat hive). Enjoy!
