Aquariums; Goldfish. with usually five yellow bands, more distinctly marked on the body whorl It has four to five convex whorls, the first a mere dot and the body whorl very wide and exceed- ing half the shell in length. All are rounded and sharply fig. 145. Georgia Snail, ymiparus georgianus. defined, with impressed suture. The operculum is bluntly pearshaped and thick, with well defined lines. The body is dark brown, spotted with yellow, the snout broad and the tentacles long and divergent. The eyes are placed on the outer bases of the tentacles. It is ovoviviparus and harmless to aquatic plants when sufficiently fed, and bears a close resem- blance to the foregoing. Quite generally distributed throughout the Middle and Southern States; first found at Hopetown, Georgia. Known as the Georgian Snail. Also note the Japanese Snail, V. malleatus hereafter described. Campeloma. These snails inhabit still water and slow-flowing streams. The shells are thick, heavy and about as long, but narrower than the foregoing, and the whorls flatter and not as rounded. The larger Eastern and Middle States species rarely exceed i Y^ inches in length and most of the specie^ less than ^ inch. C. decisum. Fig. 146, is common in ponds and nearly all freshwater in the Eastern section of North America, from Nova Scotia to the Rio Grande. The i/^ to i inch long shell is elongate-ovate, rather thick and heavy with a smooth surface not very considerably marked by lines of growth. Its color is greenish with ir- regularly disposed brown lines of growth and is usually eroded at the apex so that of the five whorls sometimesbuttwoor three FIG. 146. Campeloma decisum. remain. The body whorl is about two-thirds the length of the shell, the aperture oval-oblique more than half the length of the body whorl, and the operculum is elongate- ovate with a thi
