second, third, and fourth pairs rather longer, the outer branches armed 

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

Length, exclusive of tail setae, 1*3 mm. Anterior antennae furnished 

 with numerous moderately long and densely plumose seta ; the relative 

 length of the joints are shown by the formula —

Middle joint of posterior antennae short, bearing a single small hair, the 

 last joint covered with small prickles and furnished with three pectinate 

 setiferous appendages and three apical setae (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 setae ; 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 setae. 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 setae short. 



Habitat. — "Fluke Hole " off St Monans, Firth of Forth. This curious 

 copepod seems to be closely allied to the Saphirinidce, 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 in G. O. Sars' excellent work, the ' Crustacea 

 1 of Norway,' that the species was recognised. The largest of the Forth 

 specimens measure 20 mm. (fully three-quarters of an inch) in length.
