which are very slender; the margins of both joints are 
densely ciliated ; in the male the fifth foot 1s very small 
(fig. 12), the basal joint almost obsolete, and bearing 
only two setz, one external and one internal; second 
joint small and ovate, 4-setose. The first abdominal 
segment has a pair of bi-setose appendages resembling 
a rudimentary foot (fig. 14). Length oth of an inch 
(85 mm.). 
The anterior antenne of this species vary a good 
deal in the comparative lengths of the different joints, 
and sometimes one of the joints is altogether deficient 
(fig. 3). The outer branch of the first foot is often, 
if not always, 2-jointed owing to the coalescence of the 
second and third jomts—a condition which is met 
with frequently in other members of the genus. Though 
not agreeing quite accurately with the figures given in 
Claus’s memoir, this must, I think, be taken as a 
northern variety of L. similis, Claus. It is, perhaps, 
the commonest British species of the genus, occurring 
from above high-water mark to a depth of several 
fathoms. Occasionally also it is “ound in brackish 
pools, as for instance at Isle Oronsa, Skye (fev. A. M. 
Norman),and at Clifden, Co. Galway. The following are 
the stations from which I have specimens : —Amongst 
weeds in rock-pools, between tide-marks at Sunderland 
and several places on the Northumberland coast; Isle 
of Aran, Clifden, Westport, Roundstone, and Ventry 
Bay (Ireland); Scilly Islands, dredged in fourteen 
fathoms, and plentiful on weeds between tide-marks.
