Epiphragmophora infumdta, Gld., the SmokySnail, is commonly reckoned as a variety of thelast species, but it is so different that I prefer toconsider it as distinct. It lives along the north-ern coast region of California. In size it is similarto E. fidelis, but the shell is much depressed andflattened, and the body-whorl has a sharp, angularedge, or keel. The shell has a peculiar cloth-likesurface, and is of a nearly black color umbilicus is distinct, and the aperture veryoblique. E piphra gmophor a mor-monum, Pfr., the Mormon(Island) Snail, is shown inFigure 106. The shell islarge and depressed, the sur-face glossy, and the browngirdle is edged with white. There is a large umbil-. 128 WEST AMERICAN SHELLS iciis, and the lip is recurved. This species lives inthe Sierra Nevada Mountains, and was first namedfrom specimens taken on Mormon Island in theAmerican River. It does not live in Utah, as onewould at first suppose. There are several varieties. Var. cala, Pils., issmaller and less depressed. It is dark reddishbrown in color. The types are from the CalaverasBig Trees. Var. huttoni, Pils., resembles the lastin color, but the shell is more depressed, and thesurface is set with little prominences that bear gol-den brown hairs. Var. hillehrdndi, Newc, is some-times reckoned as a distinct species. The shell isyellowish horn color, with a chestnut band bor-dered by white. In fresh specimens the shell ishirsute. This variety also comes from the moun-tai
