CRUSTACEA COPEPODA. II. Ir 
Occurrence. — Not taken by the “Ingolf”’, but by Dr. F. Borgesen in May 1808. 
Feeroes: Glyvenes near Thorshavn, Strdm6; 1 female. 
Distribution. — West coast of Norway at Aalesund, Io fath., and at Kalvaag (G. O. Sars) ; “distri- 
buted round the British Islands’’, both in surface-net during night and dredged, down to forty fathoms (Brady) ; 
Wimereux and Pas-de-Calais, in low water (Canu); in the Mediterranean at Triest (Claus) and at Naples 
(Giesbrecht). — G. M. Thompson’s statement (1883) that this species occurs in Otago Harbour, New 
Zealand, is most probably wrong. 
11. Acontiophorus antennatus n. sp. 
(Pl. I, figs. 7 a—7 d.) 
Female. — This species is closely allied to A. scutatus, but differs in a few particulars. Two spe- 
cimens are to hand, the large one 1.23 mm. long (caudal rami included), thus somewhat larger than A. scutatus, 
while the other specimen is 0.79 mm. — Antennule with 11 joints and completely as in A. scutatus, excepting 
that the distal sensory filament preserved (in the large specimen) is considerably longer than the whole 
antennula. — The antenne differ materially from those in A. scutatus; in the inner ramus the second joint 
is from about half as long again to twice as long (fig. 7 b) as the first, and near the end with about 4 spines 
instead of setze; the outer ramus is long and reaches far beyond the middle of second joint of the other ramus; 
the peduncle has a few setae somewhat from the end. — Sipho considerably shorter than in A. scutatus, as 
in the large specimen it reaches to the middle of the genital segment, in the small specimen scarcely to the 
base of that segment. — Maxille (fig. 7c), maxillipeds (fig. 7 d), and the other appendages do not seem to 
show any appreciable difference from those in A. scutatus. — Caudal rami in the small specimen scarcely 
as long as third plus half of second abdominal segment, and each ramus is only two and a half times as long 
as broad; in the large specimen the rami are elongated (fig. 7 a), as long as the two posterior segments together, 
and each ramus is only a little less than five times as long as broad. 
Remarks. — It is only after prolonged hesitation that this species is established. Giesbrecht has 
pointed out some variation in A. scutatus, but the fact that the sipho is considerably shorter than in A. scu- 
tatus, together with the striking differences in the antennee make the reference of the two specimens to A. scu- 
tatus rather difficult. The strong difference in length and slenderness of the caudal rami between the two 
specimens is curious, but may be due to age. 
Occurrence. — Taken by the “Ingolf’”’ at a single deep station. 
Davis Strait: Stat. 36: Lat. 61°50’ N., Long. 56°21’ W., 1435 fathoms, temp. 1°5; 2 females. 
Metapontius n. gen. 
Cephalothorax in the female greatly expanded, in the male considerably more narrow; the head in 
the female exceedingly large with the postero-lateral corners nearly rectangular and not produced, while 
third and fourth segments are very short, and the sternite of the fourth is extremely short. — Abdomen short 
with the genital segment of very moderate breadth; caudal rami rather large. 
Antennulz proportionately somewhat short, in the female with 14, in the male with 17 joints. — An- 
tennee robust, 4-jointed as usual, with thick distal spines; an exopod not discovered (? wanting or rudimentary).
