the marginal spines of the outer branch are strongly

setee are plumose. The basal joint of fifth pair of feet 
(fig. 11) is short and broad, and bears three long 
plumose setze, the second joint is quadrangular, small, 
and has three apical sete, one much longer than the 
other two; in the male (fig. 12) the segments of the

Several specimens of this curious and distinctly 
characterized species were dredged twenty miles off

amongst mud in Christiania fiord in a depth of sixteen 
fathoms.
