The first snail is Euglandina rosea, the "rosy wolf snail" it is carnivorous, and eats other snails.The second snail is Zachrysia provisoria, the "garden provisoria", which can be a pest as it enjoys fruits and vegetables.These snails are both native to Florida; neither species can survive in the wild in cold climates, but both species have been introduced to other . When trying to identify the type of snail, the easiest method is to check it out closely. Nautilus, 83: 72. The coloration of the aperture and the embryonic shell is not consistent within single population samples, and the contour of the outer lip is highly variable within single drainage systems and with the age of the specimens examined. Spilochlamys is most similar to the next genus, Cincinnatia, from which its shell usually differs by having a more deeply impressed suture, more strongly shouldered whorls, and a wider umbilical perforation.

The other three forms, C. limum (Anthony, 1860), C. floridense Call,1866 and C. parthenum Vail, 1979, are exclusively apomictic parthenogens and have been separated on the basis of aperture coloration, embryonic shell coloration, and contour of the outer lip (Vail 1979a).
