long and slender, the inner branch only about half as 
long. The second pair in the male (fig. 11) is 8- 
jointed, the last joint being armed with a slender curved 
spine and four long sete. The fifth pair in the female 
(fig. 12) has a very large triangular basal joint which 
is often distinctly areolated, and has four long sub- 
apical sete; the second joint is large and ovate and 
attached by a narrow neck near the outer angle of the 
first joint; it is densely ciliated round the margins 
and has six stout sete externally. In the male (fig. 13) 
the foot is much smaller, the basal joint scarcely at all 
produced and bearing one external and two internal 
setze; the second joimt small, angular, and 4-setose. 
The caudal segments (fig. 14) are distant, moderately 
slender, and about as long as the last abdominal seg- 
ment; they bear a single stout apical seta, about 
equal in length to the abdomen, and two short lateral 
ones. Length s'gth of an inch (‘9 mm.). 
This is by no means acommon species. Mr. Robert- 
son and I dredged a few specimens in a depth of ten 
to twelve fathoms off St. Agnes (Scilly), and like- 
wise took a few amongst weeds at St. Mary’s; we 
have also taken it in Clew Bay, and at the roots of 
weeds 1n Roundstone and Mulroy Bays. I have speci- 
mens dredged by Mr. H. C. Davison in Ventry Bay. 
These are all the British localities known to me, and 
the species would seem, therefore, to be distributed 
chiefly, if not entirely, on our western shores. As 
Dr. Claus’s specimens, however, were taken at Heli- 
eoland, it is probable enough that it may be found 
also upon the east coast of Britain.
