Euchaete Bradyi n. sp. (PI. VI fig. 9 a; text-figs 53 a—b). Description. Size: 8-0 mm.; anterior division 5-5 mm.; urosome 2-5 mm. The anterior division is about xz as long as the urosome, which is about as long as the abdomen is wide. The lateral corner is rounded, with a heavy tuft of hairs. The proportional length between the abdominal .so- mites is 40, 25, 25. The ventral surface of the three last ab- dominal somites possesses a number of short delicate hairs. The gniital somite is i-6 as long as wide, but, on account of the high ventral protuber- ance, only i-i as long as deep; no posterior process is found on the left side. The subapical seta is broken, but is probably longer than St. 2. The ante- rior flange on the side of the vulva is rather short, with a somewhat convex outline, when observed in lateral view; the posterior margin is rather prominent The vulva is covered by the lateral flanges, in any case in front, to a greater extent tlian in the other species; the triangular plate in front is indistinctly developed; posteriorly a median incision is found, on each side of which a complicated chitinous framework is found (text-figs 53 a—c). The antennulae extend somewhat beyond the end of the abdomen; the appendages are like those of E. norvegica; the segments 24cn2 25 are i-i as long as segment 19. The Le of the maxillulae possess two short and 5 long setae; the basipodite has 5, and the Ri 3 (-4 + 3 setae. The other mouth- limbs do not show features of an\- interest. The articular line between
