Color light, but thickly spotted with dark grayor black markings, which cause it to resemble closely the sand. Inmuddy localities, where the bottom is darker, the spots are morenumerous and larger, so that the animals have an almost uniformcolor. They are found on the bottoms of the bays in shallow water,either lying upon the sand or buried in it with only the eyes andantennae exposed. It is a very active form, springing quickly awaywhen any attempt is made to capture it but it needs all its powersof concealment and action, for it is hunted by many fishes, and,according to Verrill, it constitutes the principal food of severalspecies, among which are the weakfish, bluefish, flounders, stripedbass etc. It is a very widely distributed species, occurring all over thenorthern hemisphere. It is the edible shrimp of Europe. DeKay. /. c. 1844. 132 NEW YORK STATE MUSEUM Family palaeimonidae Palaemonetes v
