new or rare Crustacea from Scotland. 239 
of the first four thoracic feet are all two-jointed; the fourth 
pair in the female and male are dissimilar—those of the female 
do not differ much from the others except that they are rather 
shorter and stouter, but in those of the male the inner branches 
are almost obsolete, being reduced to two minute joints, while 
in striking contrast to these the outer branches are robust and 
are armed with several stout spines in place of sete; the 
first joint of the outer branches is considerably longer than 
the next two together (fig. 12). The fifth pair in the female 
have both joints broadly foliaceous and subquadrate, and bear 
a number of strongly plumose terminal sete ; in the male the 
fifth pair are rudimentary and consist of a slightly produced 
basal portion carrying four sete, in addition to a small spine- 
like seta on the inner margin (fig. 13). The caudal stylets 
-are covered with cilia, and are about two and a half times 
longer than broad and equal to one and a half times the length 
of the last abdominal segment. 
Hab. In pools of brackish water at the mouth of a small 
stream at Luffness, Firth of Forth, and in similar pools at 
the mouth of the river Alness, Cromarty Firth. Not very 
rare. 
Remarks. Laophonte littorale resembles Laophonte curti- 
cauda, Boeck, in some respects, but differs very markedly in 
the structure of the fourth thoracic feet of the male (the outer 
branches are, however, somewhat similar to the outer branches 
of the third pair of the male of that species, but the propor- 
tional lengths of the joints are different). There are other, 
though less obvious, differences between the two species, as, 
for example, in the structure of the first thoracic feet and of 
the male fifth feet. The species appears to be confined to 
water that is more or less brackish. 
PSEUDOCLETODES, subgen. nov. 
Resembling Cletodes, Brady, in general appearance, but 
the imner branches of the first thoracic feet are obsolete or 
rudimentary ; inner branches of the second, third, and fourth 
pairs two-jointed, the first joint very small.
