The animal from the side. 2. The first pair of perneopoda. 3. The second pair. 4. The fifth pair. 5. The urus. Diagn. Corpus carinatum, interdum serratum. Femur pedum percei parium trium ultimorum an- gustum, ter longius quam latius. Tibia pedum quinti paris quam genu plus quam duplo longior, post paullulo producta; dactylus levis. Pedes uri primi paris pedes secundi paris non superantes; pedunculus ramo interno longior; ramus externus pedum secundi ac tertii parium dimidio rami interni paullo longior. Telson segmento ultimo uri paullo brevius, pe- dunculo pedum uri ultimi paris latius ac quartam partem longitudinis pedunculi ejusdem fere sequans. The body is carinated, and sometimes serrated. The femur of the last three pairs ofpercro- poda is narrow, three times as long as broad. The tibia of the fifth pair is more than twice as long as the genu; the lower hind corner is only a little produced; the dactylus is smooth. The first pair of uropoda do not attain the apex of the second pair; the pe- duncle is longer than the inner ramus; the outer ramus of the second and third pairs is a little more than half as long as the inner. The telson is a little shorter than the last coalesced ural segment; it is broader than, and not fully a fourth part as long as, the peduncle of the last pair of uropoda. Colour. Red, or light red, with the rami of the uropoda deep red. Length. 15—33 mm. Hab. The Antarctic regions; the Southern temperate regions (D. M.; F. M.; K. M.; P. M.; S. M.; U. M.) Syn. 1825.
