FAMILY COLIMACEA. 97 



foreign species to A. acicula, so near indeed as to be mistaken for it, 

 is a minute Indian species, A. B alarms, inhabiting the banks of the 

 Jumna. The only other European AcJiatina is one of which the 

 shell is an inch and three-quarters in length, A. Algira, a native of 

 the provinces of Austria and Italy, the Morea, some of the islands 

 of the Mediterranean, and Algeria. 



A. acicula lives buried under stones or at a depth of several 

 inches in the soil, and both animal and shell are colourless. The 

 animal is also supposed to be without eyes.
