Female-——Secondary branch of posterior antenne nearly 
as long as the primary branch, six-jointed, all the joints 
rather longer than broad. Inner branches of second pair of 
swimming-feet in both sexes conspicuously elongate, being 
much longer than the outer branches, or fully two and a half 
times longer. Fifth pair of feet foliaceous: those of the 
female consist of a moderately long inner segment, obovate 
in outline, bearing three sete of moderate length and two 
very small ones on the outer distal margin, and one long 
and two short terminal sete ; a long stout and curved seta 
with a minute hair, arising from its inner aspect and near 
the proximal end, springs from the inner part of the basal 
joint; this spine-like seta is distinctly articulated to the 
basal joint. The rounded posterior dorsal margin of the last 
abdominal segment bears three spiniform processes, the central 
one large and easily observed, the lateral ones smaller. The 
postero-lateral angles of the cephalo-thoracic and abdominal 
segments acutely angular. Caudal stylets short, slightly 
divaricate. Length, 1-5 mm. (,4,th of an inch). One 
ovisac. ) 
One of the most prominent characters of this species, and 
one by which it is readily distinguished, is the very long 
inner branches of the second pair of swimming-feet. 
Longipedia coronata is common all over the Forth, and 
especially so off Musselburgh.
