REVISED REPORT ON L.M.B.C. COPEPODA. 101 



First, second, third, and fourth swimming feet (figs. 

 9 — 1 1) all three jointed in both branches with the exception 

 of the inner branch of the second feet in the male (fig. 10) 

 in which a pair of stout claws takes the place of the 3rd 

 joint. The inner branch of the first pair (fig. 9) is nearly 

 twice the length of the outer, its basal joint being about 

 equal in length to the two following joints. Basal joint 

 of fifth feet (fig. 12) broad and long in the female with 

 fine terminal spinous setse. Second joint ovate with 

 several lateral spines and long terminal spine. The fifth 

 feet of the male (fig. 13) are smaller and more angular 

 than those of the female and have fewer spines. The 

 caudal stylets are slightly tapering towards the apex and 

 are about three times as long as broad. A few specimens, 

 male and female were dredged in jnud at 39 fathoms 

 in the Irish Sea about 12 miles west from Port Erin. 

 The hirsute character of the antennae, the inner branch 

 of the second foot in the male together with the caudal 

 stylets serve to distinguish the species from others of the 

 genus. 



Ameira longipes, Boeck. (PL XIX, fig. 7.) 

 Length 0.45 mm. Dredged in 20 fathoms off the Calf 

 of Man, also off Puffin Island, and the Little Orme. 

 Brady speaks of the perplexing resemblance between this 

 species and Stenhelia ima. The length of the caudal 

 segments however readily distinguishes them, being about 

 five times as long as broad in the former and very short 

 in the latter species. 



Ameira attenuata, n. sp. (PI. XXXII, figs. 1 — 11.) 

 Length 0.40 mm. Rostrum short, obtuse. Anterior 

 antennae (figs. 3 and 4) eight jointed in the female, seven 

 jointed in the male, the short penultimate joint being 

 absent in the latter. The second joint is much longer and 

 wider than any of the others. In the male (fig. 4) a hinge
