I4 CRUSTACEA COPEPODA. II. 
single specimen of each of the three species is to hand; besides the quality of the specimens was not very good. 
I hope, however, that the following descriptions with figures are fully sufficient for making the forms easily 
recognisable with absolute certainty, especially as the distal part of dactylus with claw of the maxillipeds 
affords excellent specific characters in showing — under a rather high magnifying power — great differences 
in the equipment with minutes spines, tubercles, etc. I have also arrived at the result that forms referred 
to the same species by different authors are in some cases scarcely identical, and that a revision based on a 
large material from many localities far from each other is much needed. 
14. Bradypontius groenlandicus 2. sp. 
(Pl. II, figs. 2 a—z2 m). 
Female. — Cephalothorax a little less than half as long again as broad. The head more than three 
and a half times as long as the free thoracic segments combined, with the postero-lateral corners somewhat 
produced but rounded, and anteriorly no dorsal crest. The corners of the free thoracic segments much pro- 
duced (fig. 2 a), acute; third segment very short, and its posterior angles reach about or not fully as far back- 
wards as those of second segment. — Genital segment (fig. 2 b) somewhat less than twice as broad as long; 
the two following segments short, together about as long as the terminal segment, which is conspicuously 
broader than long. Caudal rami about as long as the terminal segment, broad. 
Antennulee (fig. 2 c) somewhat less than half as long as the head, with 11 joints; the second joint is 
rather short, the third as long as the three following joints combined, the fifth as long as the sum of fourth and 
sixth, seventh joint slightly longer than the fifth and considerably longer than the eighth which is a little 
shorter than ninth and tenth joint together; eleventh joint slightly longer than the three preceding joints 
combined. — Antennee (fig. 2 d) slender; terminal joint somewhat longer than the third, and its middle apical 
seta is long. — Sipho reaches to the middle of the sternite of second free segment; its proximal part is some- 
what slender as in B. magniceps as figured by Sars. — Maxillulee (fig. 2 e) slender, with the inner branch 
considerably longer than the outer, and the terminal seta of the first-named branch is long (though its distal 
part is lost); the terminal setee on the outer branch long, but the longest one is broken. — Maxillee (fig. 2 f) 
have the dactylus with claw slender and somewhat longer than the proximal portion; the claw is somewhat 
long with a close row of tiny spines along somewhat less than the proximal half of its concave margin (fig. 2g), 
and on the proximal half of one of its sides with a close row of tiny triangular denticles; the distal part of the 
dactylus has a rather long lateral spine about as far before the claw as the length of the latter, furthermore 
a little before the long spine a short, tumid spine on the other side of the dactylus near its concave margin, 
and finally somewhat beyond the long spine and on the same side a rounded protuberance with a number 
of tiny, slender denticles. — Maxillipeds (fig. 2 h) normal; the claw as long as the dactylus; which consists 
of three joints. — Fourth pair of legs (fig. 2 1) with the endopod only about as long as the two proximal joints 
together of the exopod, but its joints are conspicuously broader than in any of the Norwegian species figured 
by Sars. — Fifth legs is a minute joint as broad as long, with three bristles. 
Length 2.25 mm. 
Male. — Cephalothorax (fig. 2k) more slender than in the female, about two-thirds as long again
