inner branch having four long apical setae, 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 limb 

 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 setae on the outer, and three large and one short 

 on the inner margin, the rest of the margin being 

 shortly ciliated ; second joint very broadly ovate, 

 angulated internally, and bearing several slender setae 

 of various lengths ; in the male (fig. 9) the fifth pair 

 has both branches narrower, more angular, and some- 

 what less profusely setose. Length -^nd. of an inch 

 (79 mm.). 



This species is not unfrequently taken in the surface- 

 net not far from the shore, in tidal pools amongst Algce, 

 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, Clif den, 

 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 Laminarice 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-
