Appendices to Fourth Annual Report 



beset with spines and long plumose setae. In the female the fifth pair 

 of feet are two-jointed, the first joint being short, the second elongated, and 

 bearing small cilia on the margin, and long setae at the apex. It is much 

 the same, but smaller in the male. The fourth and fifth abdominal 

 segments, as well as the caudal segments, are exceedingly short ; on the 

 other hand, the inner tail setse are about as long as the entire animal, the 

 outer setje are about half that length. This copepod was found in toler- 

 able abundance in the months of February and March of this year. 



Sciitellidium fasciatum (Boeck). — Cephalothorax broad and ovate, seg- 

 ments of thorax produced backwards into strong pointed processes. Ab- 

 d )men somewhat conical. Caudal segments very short, but inner setae 

 extremely long. Anterior antennas nine-jointed, slender, and tapering, 

 the male right antenna is hinged between the fifth and sixth joints. 

 The swimming feet are densely covered with setae and have also rows of 

 long spine-like hairs. The fifth pair in the female are two-jointed, the 

 first joint bearing at its distal end a seta on each side ; the second hav- 

 ing terminal setae, and both being ciliated on the outer margin. In the 

 male the fifth foot is similar but not so large, reaching only to the first 

 abdominal segment, whereas that of the female reaches the last segment 

 of the abdomen. This species was rather rare. 



Artotrogidje. 



Cyclopicera nigripes (Brady and Robertson). — Cephalothorax broad ; 

 abdomen somewhat tapering, the first two segments produced laterally in 

 sharp spines. Caudal segments are short and broad, the terminal setae 

 plumose. Anterior antennas nineteen-jointed and tapering, the second last 

 joint bearing an olfactory organ. First four pairs of feet short, both 

 branches three-jointed ; fifth pair two-jointed. The male has four caudal 

 setae, the female five, two are about the length of the abdomen, the rest 

 are comparatively short. It was found in considerable numbers in the 

 months of February and March. 



Artotrogus magniceps (Brady). — The body is broad and ovate; the 

 abdomen composed of four segments. The mouth is produced into a 

 siphon. Anterior antennae ten-jointed and slender, bearing scarcely any 

 setae except at the apex, where there is also an olfactory appendage. 

 The anterior foot-jaw has a small claw near the apex. The swimming-feet 

 have their first and second joints densely ciliated on the outer margin, and 

 at each angle bear a number of lancet-shaped spines. The last joint has 

 five plumose setae on its inner margin, and a long serrated spine at its 

 apex. Fifth pair of feet one-jointed, quadrate, bearing one long and two 

 short apical setae. Only some two or three specimens of this copepod 

 were found in February and March.
