Oxychilus cellarius (Muller) 
This species is intermediate in size between O, alliarius and O, drapar- 
naldi; shells (with 5 whorls) measure about 9 mm. The general shell 
shape, color, and relative size of the umbilicus are similar to the above 
two species. The light gray color of the animal, however, immediately 
distinguishes it from the other two species that have dark gray or black 
bodies. It is further distinguished by its more broadly lunate aperture. 
Distribution: Europe, Asia Minor, North Africa. Introduced into the 
United States and there are now records from many of the Northern States. 
Family TESTACELLIDAE 
This family consists of sluglike snails, which bear a small rudimentary 
shell near their posterior end. They are carnivorous, preying on soil 
invertebrates. One species, Testacella haliotidea, has been occasionally 
found in greenhouses in this country, and has apparently become success- 
fully established in parts of Tennessee, 
Testacella haliotidea Draparnaud 
Plate Jil; °A;-Pipure 105 7A: 
Shell rudimentary, depressed, ear-shaped, imperforate, and with a sub- 
spiral, posterior nucleus. The surface is rugosely striate. The apex is 
very small and short and is not separated from the columellar margin. 
The aperture is oval. Adult shells measure 6-10 mm. in length. 
The animal is sluglike, tapering anteriorly, and is much too large to re- 
tract into its shell. The mantle is covered by the small, posteriorly 
placed shell. 
Distribution: Great Britain, Western Europe, Algeria, Madeira, Canary 
Islands, Introduced into Cuba and the United States (Tennessee, and in 
greenhouses in Philadelphia, Chicago, and Berkeley, Calif. ). 
This species spends much time in the ground, and in its native countries 
apparently feeds chiefly on earthworms.
