with hooked marginal spines. Tifth pair nearly as in Lichomolgus.

with numerous moderately long and densely plumose seta; the relative 
length of the joints are shown by the formula—

Middle joint of posterior antenne short, bearing a single small hair, the 
last joint covered with small prickles and furnished with three pectinate 
setiferous appendages and three apical setz (fig. 3). The mandibles (?) have 
the basal portion considerably dilated, d the terminal portion curved and 
stylet-shaped (fig. 4). First pair of swimming feet short, broadly foliaceous, 
somewhat distorted ; joints of inner branch subequal in length ; the middle 
joint of the outer branch very short (fig. 7). The second and third pairs 
longer and much narrower comparatively than the first; inner margins 
furnished with elongate, densely plumose sete; the exterior margin and 
end of the outer branches armed with stout spines bearing terminal hook- 
like processes ; joints of the inner branches subequal; middle joint of 
outer branches shorter than either of the other two (fig. 8). In the 
fourth pair the inner branches are rather longer than the outer, but other- 
wise this pair is similar to the second and third. The fifth pair consist 
each of a single two-jointed branch; the first joint is very short, the 
second is about four times the length of the first, and is provided with 
three terminal and one marginal sete. Abdomen short, tapering from the 
somewhat stout genital segment; the third, fourth, and fifth segments 
shorter than the preceding one. Caudal stylets rather longer than the 
last abdominal segment; the principal caudal seta is about one and 
a half times longer than the abdomen ; other tail setz short. 
Habitat.—‘‘ Fluke Hole” off St Monans, Firth of Forth. This curious 
copepod seems to be closely allied to the Saphirinidee, and probably belongs 
to that group. The peculiar structure of the first pair of swimming feet 
give it a somewhat abnormal character. New to Britain. 
Besides the Copepoda now described, there are still some others that do 
not apparently agree with known species, and which are held over for 
further study.

Several specimens of this fine Species were obtained in February 1889, 
near May Island, Firth of Forth? but were not then recorded ; it was only 
when I read the description i in G. O. Sars’ excellent work, the ‘Crustacea 
‘of Norway,’ that the species was recognised. The largest of the Forth 
specimens measure 20 mm. (fully three-quarters of an inch) in length.
