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

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

 transparent consistency, the rugae 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. occidentaUs^ Cooper, of California, appears to differ only 

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

 differs slightly in the details of dentition ma3 r likewise need to 

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

 Weinlandi, Heynemann, is probably a synonym.
