Taken by Kmusser. wikipedia.org.The Dryland Liptooth, Linisa tamaulipasensis, are native to the United States and are found most abundantly in the central and western Edwards Plateau of Texas (Pratt, 1981), more specifically within the Chihuahuan desert.  They live near the mouth along the drift of the Rio Grande where it is rather arid within the counties of Kimble, Mitchell, and Brewster (Pratt, 1981)

The Chihuahuan Desert is the largest desert in North America and resides mostly in the states of Chihuchua and Coalhuila of Mexico, however, a small portion of its tip reaches up to Texas, southern New Mexico and western Arizona (New Mexico State University, 2011).  It resides between the Sierra Madre Occidental, which is located to its west, and the Sierra Madre Oriental located to its east thus making it also known as a rain shadow desert (New Mexico State University, 2011).  The Chihuahuan Desert has a vast range of elevation ranging from

The Linisa tamaulipasensis are genuinely found in shrub savannah on calcareous slopes, slopes rich in calcium carbonate, and uplands (Pratt, 1981).  The snails living on the western end of their range of habitat often burrow in loose soil amongst limestone talus and restricted to those slopes and the snails living on the more eastern end are restricted to well drained ridge tops (Pratt, 1981).
