Colour (as preserved); ground colour whitish, with purple patches on head, peraeon and pleon, side-plates, and 2nd joints of peraeopods 3-5, the patches on the body more or less in the form of transverse bands. Colour of no. 1 is given as 'very pale yellow blotched and mottled with brown, eyes pale grey'. Remarks. This extraordinary species may remain in the genus Eurystheus. Its general appearance is that of a species of this genus, though sexual dimorphism has been carried to an extent found in no other species. The 2nd side-plate resembles that of Megamphopas cornutus (Sars, 1895, pi. xx). Eurystheus purpurescens, (Fig. 140). Occurrence: 1. St. 39. South Georgia. 1 S 9 mm., 1 $ 11 mm., 1 immat. $ 8 mm. 2. St. 167. South Orkneys. 2 S3 20 mm. Type 3- 3. St. 190. Palmer Archipelago (90-130 m.). 1 ovig. $ 8 mm. Type $. Description. In general appearance and coloration similar to ditnorphus, but eye slightly larger, post-antennal angle of head quadrate, 2nd peraeon segment only half as b Fig. 140. Eurystheus purpurescens, a, b. Gnathopods 1 and 2 (both viewed from inside), c. 2nd joint of peraeopod 5, with hind margin further enlarged. long again as segment 1, and no denticles on any of the pleon segments. Telson with an apical spinule as well as one on each lateral corner in 3, only the lateral ones in ?. Epistomial spine strong, moderately long. Antenna 1, flagellum in <$ 39-jointed, accessory flagellum 8-jointed. Antenna 2, flagellum in S 27-jointed. In ? flagella of both antennae 15-jointed, accessory flagellum 6-jointed. In S of no. 1 flagellum of antenna 1 16-17-jointed, accessory flagellum 5-jointed, of antenna 2 15-join
