Arizona: Marble Peak, Santa Catalina Mountains; Type 109078 A.N.S.P., from Station 26, a quartzite slide on Marble Peak. Also found at many other places on the same mountain, at about 6-7000 feet, and northward to the foothills (J. H. Ferriss).
The only comparable species of the Santa Catalinas is S. sabinoensis, which is far less depressed than marmorarius, with smaller umbilicus and a larger aperture. In form and embryonic sculpture it agrees well with S. hacitana, but in that species the verge is constantly shorter. S. compar is a thinner shell, and the penis tapers to a slender tube towards the base.
