REVISED REPORT ON L.M.B.C. COPEPODA. 195 
First, second, third, and fourth swimming feet (figs. 
9—11) 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 sete. 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 longas broad. A few specimens, 
male and female were dredged in mud at 39 fathoms 
in the Irish Sea about 12 miles west from Port Hrin. 
The hirsute character of the antenne, 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 
seoments 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. (Pl. XXXII, figs. 1—11.) 
Length 0.40 mm. Rostrum short, obtuse. Anterior 
antennee (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
