Limax CAMPESTRIS. 
L. campestris. BINNEY, Family Limacide, op. sup. cit. 
Description. Body cylindrical, elongated, terminating in a very short carina at its posterior 
extremity. Mantle oval, fleshy, but little prominent, with fine concentric lines. Back covered 
with prominent elongated tubercles and furrows. Foot narrow. Breathing-hole on the 
posterior dextral margin of the mantle. Body covered with a thin watery mucus.

This species, according to its author, is nearly allied to the L. agrestis, with which it may 
probably prove to be identical. It is said to be much smaller, and at all ages possesses a 
peculiar gelatinous or semitransparent consistency. Its tuberosities are very prominent, and 
it does not secrete a milky mucus at every part of the surface when touched. Like agrestis, 
it is very active in its movements, and suspends itself by a mucous thread. 
It is found under decaying wood and stones. It occurs in this State and northwardly, and 
has been seen in Ohio and Missouri.
