The "slugs" or shell-less terrestrial moUusks of Indiana are hardly known. 

 Very few collections contain any i-epresentatives. Inasmuch as they do not ap- 

 peal to the conchologist and are rather difficult of preservation, requiring alcoholic 

 methods, they have been neglected. They promise useful facts if particular at- 

 tention is directed to their systematic collection. They are to be sought under 

 chips, boards, logs, flat rocks, bark, sidewalks, in cellars and about barns and 

 other outhouses in damp situations. A track of dried mucus will often lead one 

 to their hiding place, if carefully traced. They should receive especial attention 

 from the collectors of the survey.
