LAOPHONTE. 81 
imner branch having four long apical sete, and a very 
stout beak-like spine at the outer angle; the last joint 
of the outer branch has four very large terminal spines, 
the longest of which is nearly as long as the hmb 
itself; and besides these, there are five or six small 
subsidiary spines attached between the bases of the 
larger ones; the outer margins of both branches are 
densely clothed with spine-like cilia. Fifth pair (figs. 
7 and 8) short and broad, basal joint broadly trian- 
gular, its inner portion large, bearing four or five 
short set on the outer, and three large and one short — 
on the inner margin, the rest of the margin being 
shortly ciliated; second joimt very broadly ovate, 
angulated internally, and bearing several slender setz 
of various lengths; in the male (fig. 9) the fifth pair 
has both branches narrower, more angular, and some- 
what less profusely setose. Length s';nd of an inch 
(79 mm.). 
This species 1s not unfrequently taken in the surface- 
net not far from the shore, in tidal pools amongst Alga, 
and by the dredge in small depths of water. I have 
found it on mud-covered rocks at Whitburn (Durham), 
amongst weeds at Sunderland, Little Cumbrae, Clifden, 
Roundstone and Westport, and in tow-net gather- 
ings from Westport Bay. It occurs also amongst 
Copepoda dredged by the Rev. A. M. Norman at 
Oban, in a depth of five fathoms, and is common in 
washings of Laminarie from Hillswick, Shetland. 
The short and broad fifth foot, with the remarkable 
angulation of the inner margin of its second joint, in 
the female, together with the strongly marked cha-
