Subclass PULMONATA 
Order SYSTELLOMMATOPHORA 
Family VERONICELLIDAE 
This is a tropical family of primitive slugs that have their eyes on con- 
tractile (not inversible) stalks or tentacles (see fig. 3), The mantle 
covers the entire back of the animal and contains neither an external nor 
internal shell. The lung is posteriorly located, with the breathing pore 
and excretory openings behind the foot. Only one species (Veronicella 
floridana), found in Florida, is native to the United States.

median whitish line with a long dark longitudinal band on each side about 
1/3 the distance to the mantle margin, The mantle covers the entire back 
of the animal. Adults are 70-90 mm, long.

Order STY LOMMATOPHORA 
Division AULACOPODA 
Family ARIONIDAE 
This family of slugs, and also the Limacidae, have their eyes oninversible 
(not contractile) tentacles (see fig. 3), and have a mantle that covers only 
the anterior part of the body and which contains only an internal vestigial 
shell. Arion, of this family, can be distinguished from the limacid slugs, 
Milax, Deroceras, and Limax, by the position of the breathing pore. In 
the latter genera it is located in the posterior half of the mantle; in Arion 
in the anterior half. 
Distribution: Holarctic in distribution, with species native to western 
North America, Asia, Europe, and Africa,
