CRUSTACEA COPEPODA. II. 19 
Distribution. — In Norway at Kvalé, on the Nordland coast, 40-50 fath. (G. O. Sars); further- 
more east of Hope Island (south-east of Spitzbergen), roo fath., and off Kolgujew Island (rather far south- 
west of Novaya Zemlia) (Th. Scott). 
Pseudomolgus G. O. Sars. 
This genus is the only representative for the family Lichomolgide sens. Sars hitherto found in the 
“Ingolf” area, and even only a single species has been discovered. Sars describes in his Account 8 genera 
with 24 species from Norway, and it must certainly be possible to collect several of these forms at the Feeroes, 
Iceland or Greenland.

(Pl. II, figs. 7 a—7 g.) 
Female. — In general aspect rather similar to P. dilatatus G. O.S., but it differs from all 3 Nor- 
wegian species in some features. — The body is nearly half as broad as long (caudal rami included) and 
broadest at the posterior angles of the head (fig. 7 a); the abdomen is shorter in proportion to the cephalo- 
thorax than in other species. The front part of the head is a little produced between the antennule, which 
therefore are inserted on the sides of this quite short frontal plate. Last thoracic segment broader than the 
genital segment, which is slightly broader than long (fig. 7 b); second and third abdominal segment very short, 
taken together even conspicuously or slightly shorter than the anal segment, which is about as broad as 
long and somewhat shorter than the genital segment. Caudal rami only a little longer than the last segment, 
and the seta on the outer margin is inserted distinctly before the middle. —- Ovisacs large, very oblong, 
with numerous small eggs. 
Antennule (fig. 7c) as usual 7-jointed, a little shorter than the head; fifth joint as much shorter 
than the fourth as longer than the sixth. — Antenne (fig. 7 d) very robust; first joint with a slender and small 
process near the end; the 4 apical claws strong, with a very sharp bend or a kind of articulation at the middle, 
while their distal half is very much curved; the sete on the last joint may be seen on the figure. — Distal 
portion of the maxille (fig. 7 e) characteristic, with 6 processes, the first rather short and not marginal, 
the four following processes marginal and strong, while the terminal process is unusually long and distally 
thin. — First legs when seen from below (fig. 7 f) with rows of fine spines at the outer distal edge of first 
joint, and on the distal margin of second joint at both sides of the origin of the endopod, furthermore on 
half of the outer margin of first joint of the exopod and along the outer part of the distal margin of first 
joint of the endopod; endopod much more slender than in the Norwegian forms, with the third joint long, 
while the second joint is about half as long as the third; the exopod has the first joint long and very broad, 
expanded outwards, with the outer margin very convex, the second is not half as long as the first. The number 
of setze and spines on these legs as in P. dilatatus; in second to fourth pair of legs the terminal joint of both 
rami possesses 3 spines on the outer margin, besides the terminal spine. — Fifth leg (fig. 7 g) not quite three 
times as long as broad, thus broader than in the Norwegian forms; the lateral margin is not ciliated, but 
on the broad end bearing the long terminal spine some 5 or 6 fine denticles are seen.
