COCHLICOPIDAE 



Family COCHLICOPIDAE 



Shells of the family Cochlicopidae are long, cylindrical, 

 smooth and shining. They are without umbilical openings. 



Genus COCHLICOPA (Ferussac) Risso 



The animal of the genus Cochlicopa is blue-black in color, 

 lighter on the foot, which is broad in front and tapering toward 



the posterior end. The eye 

 peduncles are long and are 

 enlarged at the extremity, 

 but the tentacles are very 

 short. The shell is car- 

 ried partly erect when the 



animal is in motion as in the above figure of Cochlicopa lubrica. 

 One species and one variety of Cochlicopa live in North America. 



COCHLICOPA LUBRICA (Muller) 



With a shell close to one-fourth inch (6 mm.) in length, 

 Cochlicopa lubrica cannot be mistaken for any 

 other species found in Illinois. Its almost cylin- 

 drical form, shining surface and bright horn 

 color at once identify the shell, which has six 

 whorls. The spire is considerably longer than 

 the aperture. 



This snail is not common in Illinois, and the 

 records are widely scattered. In this state, its 

 habitat is varied. It is found in ravines and 

 isolated woodlands, usually under dead leaves 

 and loose bark of logs. It is distributed through- 

 out the northern part of the United States and 

 also throughout Europe.
