CRUSTACEA COPEPODA. II. 15 
as broad. Third free segment covered excepting the postero-lateral corners, which are far from reaching the 
end of those from second segment. 
Antennule (fig. 21) scarcely half as long as the head, 13-jointed. Third joint about as long as the 
five following joints together; tenth joint longer than the sum of the four preceding joints, with three spines 
on the outer margin, the first of very moderate length and the two others short and robust; eleventh joint 
slightly longer than the thirteenth, and both these together about as long as the twelfth. One sensory filament 
on the second, fourth, sixth, seventh, eighth and ninth joint, 3 similar filaments on the third, and 2 on tenth 
joint. — Fourth pair of legs (fig. 2 m) shows conspicuously less difference in length and breadth of the joints 
respectively in the endopod and the exopod than in the female, as the endopod is proportionately more devel- 
oped, and it terminates in a thick and very curved spine. 
Length scarcely 2 mm. 
Remarks. — This species is allied to Bradypontius major established and figured by Sars, but the 
female differs in being somewhat smaller, without dorsal crest in front, in having only 11 joints in the anten- 
nul while 13 are found in B. major; furthermore the claw of the maxillipeds is proportionately longer than 
in B. major, while the dactylus of the maxillee is more slender, but unfortunately Sars has not specially in- 
vestigated the equipment with spinules ete. of the dactylus and the claw. The male differs very considerably 
from that of B. major both in the armature of tenth joint of the antennulee and in the shape and distal equip- 
ment of the terminal joint of the endopod in fourth legs. 
Occurrence. — Taken by the “Ingolf’’ at a single station.

15. Bradypontius dentatus n. sp. 
(Pl. II, figs. 3 a—3 e). 
Female. — Only a single specimen with several among the appendages mutilated is to hand. It is 
allied to, but considerably smaller than, B. caudatus G. O. Sars, and it may nearly be sufficient to point out 
the differences observed. 
The head is somewhat more narrow (fig. 3 a); the frontal crista is broad, and the postero-lateral 
corners distinctly more produced, acute. The three anterior free segments have their lateral parts produced 
extremely backwards into very oblong lobes, which are proportionately somewhat or considerably longer 
than in B. caudatus (fig. 3 a shows the anomaly that the right lobe of first segment is much shorter than the 
left and certainly misshaped). — Abdomen proportionately slightly shorter than in B. caudatus, second and 
third segment being rather short, each much shorter than the fourth, which is a little broader than long and 
as long as the caudal rami. 
Antennule (fig. 3 b) with ro distinct joints, and an eleventh is indistinctly indicated towards the distal 
end of the third joint. When not counting that indistinct joint the fifth joint is more than twice as long as 
the fourth and somewhat shorter than the seventh; the eighth and the ninth joint both somewhat shorter 
than the seventh and together distinctly shorter than the terminal joint; in B. caudatus the joint answering 
to the seventh in B. dentatus is divided into two well developed, shorter joints. — The antenne differ from
