rous legs, I have in Fig. 36—38 given drawings of parts of this pair 
of extremities. In Fig. 36 the $th joint of the ovigerous leg of a male 
is figured, showing the row of short spines, which in this spe- 
cies on the Tth to 10th joint take the place of the denticulated spines. 
Save this row of spines the whole joint — and the other joints 
also — is covered by numerous spines placed irregularly and being 
in the females stronger and more numerous than in the males. 
The claw of the same leg is figured in Fig. 37: the elaw is not 
pectinate but shows often — and especially in male specimens — 
a row of small knobs at the inside. This claw is in the females 
as a rule much shorter: for comparison I give a drawing of it 
in Fig. 38, which has been magnified as strongly as Fig. 37. The 
length of the ovigerous leg is not very considerable, being with 
males and females about as long as the body. The genital opening 
of the female is very large and found at the second joint of every 
leg. In Fig. 39 I give a drawing of it. The genital pores of the 
males are very small (Fig. 40) and occur only, at the third and 
fourth leg. Yet in numerous specimens I looked in vain for the- 
se pores; but as some of the latter specimens were furnished with 
young ones firmly attached to the ovigerous leg, and as they were 
by no means females, the large genital openings of these being very 
easily observed, I believe to be quite right in supposing that these 
specimens without distinet genital pores were males. 
A male specimen with young ones I figured in Fig. 35. The young 
ones remain for a very long time with their parent, till they form a 
very large mass of bodies and legs covering the whole ventral side 
of the animal. Of the rostrum, the palpi and the ovigerous legs 
nothing is to be observed: a large clew of larval bodies forms the 
central mass, from which four pair of legs and the two mandibles, 
bent over to the ventral side, seem to escape. 
The following is a complete list of the Stations where this species 
was collected during the cruises of the W. Barents 
Station N’ 8 (first ceruise: 1878). Lat. 74° 9’ N.; long. 45° 2’ E.; 
July 29, 1878. Depth of the sea 160 fathoms. Numerous young and 
12 adult specimens. 
HOEK, Pycenogonids.
