The body has a yellowish- brown color which shows through the semi-transparent shell. This snail is quite generally distributed in New York, Pennsylvania, New Jersey and Georgia. It is destructive to aquarium plants. S. retusa. Fig. 162, has a J/^ to % inch long somewhat conical ovate- oblong very thin pellucid yellowish-white minutely striated shell of three whorls, of which the body whorl constitutes nine-tenths of the entire shell and tapers gradually to the apex. The spire is short, the suture indistinct, and the aperture four-fifths the length of the shell. The body is a little longer than the shell, of a translucent greyish color marked with black spots. This snail is found quite generally in the Eastern and Middle States. Lymn^a. This numerously represented genus is found in stagnant and sluggish water, ponds and streams; feeding upon waste matter and aquatic plants, as all the genus are herbivorous and a few species also carnivorous. They are active, prolific and thrive in the aquarium, but are destructive and constant feeders, preferring the healthy growing plants to algse and decaying vegetation; though they are also effective scavengers and devour animal substances and food offal, and sometimes their own spawn. When bred in the aquarium they considerably loose their destructive habits and become feeders on algte. All are air breathers and will leave the water to rest upon aquatic
