in the first the inner margin is slightly lobate towards the distal end, and 
one or two moderately stout sete spring from the rounded apex of each 
lobe ; the gently rounded inner margin of the second joint is fringed with 
fiiwaic hairs, and carries one or two sete near its distal end ; the remaining 
five joints are small, the end one is provided with two short and two long 
terminal set, a long seta also springs from the inner aspect of the pen- 
ultimate joint, while the three preceding joints are furnished with a few 
seta as shown by the drawing (fig 11). 
The first four pair of swimming feet are, each of them, two-branched 
and both branches are three-jointed. The outer branches of the first pair 
have their exterior margins armed with elongated spines arranged as 
follows :—One near the distal end of the first joint, one on the second 
joint, three on the margin and one (larger than the others) at the end of 
the third joint; a single long plumose seta springs also from the inner 
margins of the first and second joints, and four from the inner edge of the 
third joint. The first and second joints of the inner branches have no 
sete or spines on the outer margin, but the first joint bears one. and the 
second two setve on the inner edge, while the third joint bears one seta 
near the middle of the outer margin, three on the inner margin, and two 
at. the apex. The armature of the other three pairs of swimming feet is 
somewhat similar to that of the first, except that the third joint of the 
outer branches of the fourth pair carries five sete on the inner margin ; 
moreover, in the fourth pair the third joint in both branches is propor- 
tionally rather more elongated, being about equal to the entire length of 
the first and second joints combined (figs. 12, 13). The spines on the 
outer margins. of the outer branches in all the four pairs are of a sabre- 
hike form, with the edges minutely serrated. 
The fifth pair of thoracic feet are each composed of a single two-jointed 
branch, the first joint is somewhat dilated, being about as broad as long, 
but the second is. narrow and moderately elongated, and furnished with 
five sete, one being situated near the middle of the outer margin, and 
four around the distal end (fig. 14). 
= Halitat.—In the stomach of a small Haddock, Gadus ceglefinus, L., 
88mm. (about 34 inches) in length, captured 65 miles east by south of 
Sumburgh Head, Shetland, September 4th, 1900, by the steam trawler 
Si. Andrew.” 
4 Remarks.—The species now described agrees in some of its more impor- 
tant characters with the genus Cyclopina of Claus; but in that genus the 
antennules are described as being shorter than the cephalic segment, 
while the number of joints in those of the species hitherto recorded 
is not more than. twenty-two or twenty-three; in C. longifurcata, on 
the other hand, the antennules are not only as long as the cephalic 
segment, but they are also apparently twenty-six-jointed; then again 
the antenne of Cyclopina are described as four-jointed, but the third 
joint is very short, whereas in our specimen the third is as long as 
the fourth joint. Notwithstanding these and one or two other minor 
differences, the specimen seems to be a true Cyclopina. Only the one 
specimen was observed ; and as it was apparently quite uninjured, it had 
probably only been a ‘short time in the Haddock’s stomach before the 
Haddock itself was captured.
