Anguispira alternata jessica Kutchka, 1938 Anguispira jessica, also known as the mountain tigersnail or mountain disc, is a species of pulmonate land snail– a gastropod mollusk in the family Discidae, the disk snails.

[2] The mountain tigersnail's shell is striated with an elevated apex, and ranges from 17 to 21 mm in diameter.

It is pale or light brown in color, with either defined or slightly blotchy reddish-brown stripes.

[1][3] There is a set of reddish-brown square-shaped markings slightly below the periphery that extend underneath the shell.

[3] Due to the scarcity of sightings and difficulty of locating new populations, it is listed as vulnerable in Tennessee and North Carolina and critically imperiled in Virginia and Alabama.
