In the neighborhood of New York we find three com- mon species. In Camhavus hdviimii, Fig. 55, the body is devoid of spines, but is pitted with little depressions scat- tered at fairly regular inter- vals. It is very abundant in running streams, and often hides away under stones or burrows into gravel. Large specimens may be three inches in length. In Gamharas hlandincjli the body and claws are besprinkled with tubercles. It is dull greenish- brown, whitish beneath and lives in clear, running streams; often resting near the surface upon water plants, with its head pointed up stream. It grows to be over five inches in length. Ctcmhariis alj'mis is the crayfish which is commonly sold in the New York markets. It grows to be a little over four inches long, and the upper surface is mottled with darker and lighter shades of green, while the tips of the nippers are orange. The under sur- face is streaked with chestnut-brown It is common in the rocky beds of rivers, and often rests under flat stones, but avoids dense clusters of water plants.
