L. CAMPESTRIS, Binney. PI. 51, figs. 8, 9. 



Color usually various shades of amber, without spots or mark- 

 ings, sometimes blackish ; head and eye-peduncles smoky ; body 

 cylindrical, elongated, terminating in a very short carina at its 

 posterior extremity; mantle oval, fleshy, but little prominent, 

 with fine concentrical lines ; back covered w r ith prominent 

 elongated tubercles and furrows ; foot narrow, whitish ; respira- 

 tory foramen on the posterior dextral margin of the mantle ; 

 mucus thin, watery. Length, 1 inch. 



United States. 



Although considerably smaller, it is nearly allied to L. agres- 

 tis, but the surface possesses a peculiarly gelatinous or semi- 

 transparent consistency, the ruga? are more prominent and are 

 not separated by darker-colored anastomosing lines ; it does not 

 secrete a milky mucus. It is active in its motions, and occasion- 

 ally suspends itself by a mucous thread. Most common in the 

 Northern and Middle States, found under decaying wood in 

 forests and in open pastures, and under stones at roadsides. 



Yar. occidentalis^ Cooper, of California, appears to differ only 

 slightly in its dentition. L. montanus, Ingersoll, which also 

 differs slightly in the details of dentition may likewise need to 

 be placed here as a variety only, as W. G. Binney surmises. L. 

 Weinlandi, Heynemann, is probably a synonym.
