According to Slabber, whose figure of one of the species has been overlooked by all Crustace-ologists, there are eight pairs of legs of equal size.] Cryptopus, Latr., has the carapax subovoid, swollen, bent under at the sides, enveloping the body, as wellas the antennae and legs, having only on the under side a longitudinal slit. The eyes are wide apart. Thelegs are like flattened threads, with a lateral appendage. Type, C. Defrancii, Latr. Mediterranean. In others, the eyes are hidden. Tlie intermediate antennae conical, exarticulated, and very short. The lateralantennae composed of a peduncle and a filament, without distinct articulations : their base is not protected by aporrected , Latr., has the body very soft; thorax ovoid; legs like flattened threads, the majority with an ap-.

Ofthese it will be necessary only to notice those of Sict/ottiii, nearlyallied to PeniEus, but differing from it and all the other genera inhaving no appendages to the false subabdominal legs, and in the modi-fications of its respiratory apparatus, there being only eleven pairs ofbranchJK instead of eighteen.
