De ovre Folere (Tab. IV, Fig. 1) er betydelig 
lengere end hos Hunnen og, lige udstrakte, omtrent 
saa lange som Forkroppen og «Preabdomen» tilsam- 
men. Skaftet skiller sig ikke vewsentligt i sin Byg- 
ning fra samme hos Hunnen, hvorimod begge de ter- 
minale Vedheng er kjendelig forskjellige. Det blad- 
formige Vedheeng er forholdsvis betydelig storre og 
mere forlenget, omtrent 4 Gange saa langt som 
bredt, eller paa det nermeste af samme Lengde 
som de to sidste Led af Skaftet tilsammen. For- 
ovrigt viser det den samme characteristiske teette, 
kostformige Borstebesetning som hos Hunnen. Svo- 
ben er serdeles sterkt forlenget, mere end dobbelt 
saa lang som Skaftet og sterkt afsmalnende mod 
Enden. Den er sammensat af 17 vel begrendsede 
Led, hvoraf det Iste egentlig representerer 3 med 
hinanden sammensmeltede Led. De 9—10 forste 
Led er steerkt opsvulmede i sit ydre Parti og her 
besatte med en tet Krands af yderst fine gjennem- 
sigtige Sandseborster. De ydre Led bliver efter- 
haanden overordentlig tynde og forlengede; dog er 
sidste Led noget kortere end de umiddelbart fore- 
gaaende. 
De nedre Folere (se Tab. I, Fig. 3) er af hele 
Legemets Leengde, Halegrenene iberegnede, og ud- 
meerker sig iser ved den overordentlig tynde og 
forlengede, af talrige korte Led bestaaende Svobe, 
der ialmindelighed er lige bagud rettet. Derimod 
skiller Skaftet sig (se Tab. IV, Fig. 2) kun lidet fra 
samme hos Hunnen. Dog er dets sidste Led noget 
tykkere og mangler de lange Fjerborster, der hos 
Hunnen udgaar fra Enden, i hvis Sted der blot fin- 
des nogle meget fine Haar. 
Kindbakkerne og Overleben viser fuldkommen 
samme Udseende som hos Hunnen. 
Ogsaa de 2 Par Kjever (Fig. 3 og 4) er byg- 
gede paa samme Maade som hos Hunnen; men begge 
Par er forholdsvis mindre og har navnlig Tygge- 
lappene meget svagere udviklede samt kun forsynede 
med yderst smaa, simple Borster. 
Branchialfodderne (Fig. 5) har den egentlige 
Stamme, eller Endopoditen, betydelig svagere ud- 
viklet end hos Hunnen og neppe overragende Exo- 
poditen. Ogsaa er de paa den festede Borster kor- 
tere og alle af ens Udseende, uden at de i Spidsen 
feestede udmerker sig ved en paafaldende Lengde. 
I Modsetning hertil er saavel Exopoditen som Epi- 
poditen seerdeles store og deres Gjellestructur endnu 
mere udpreeget end hos Hunnen. 
Bagkroppens Svommefodder er idethele kraf- 
tigere udviklede end hos Hunnen (se Tab. I, Fig. 3), 
WS 
The superior antenne (Pl. IV, fig, 1) are con- 
siderably longer than in the female, and when 
straightly extended are about as long as the 
anterior division of the body and the preabdomen 
taken together. The peduncle does not particul- 
arly distinguish itself in structure from that of 
the female while, on the other hand, both the 
terminal appendages are perceptibly. different. The 
lamelliform appendage is, relatively, considerably 
larger and more prolonged, about 4 times as long 
as it is broad, or nearly of the same length as 
the two last joints of the peduncle together. It 
exhibits otherwise the same characteristic, close, 
brush-like, bristly armature as in the female. The 
flagellum is particularly greatly: prolonged, more 
than twice as long as the peduncle, and is greatly 
narrowed towards the extremity. It is composed of 
17 well-defined joints, of which the first one really 
represents 3, which are coalescent with each other. 
The 9—10 first joints are greatly thickened in their 
outer portion, and are here covered with a close 
wreath of estremely fine, transparent sensory bristles. 
The outer joints become gradually extraordinarily 
slender and prolonged; but the last joint is some- 
what shorter than the immediately preceding ones. 
The inferior antenne (see Pl. I, fig. 3) are as 
long as the entire body, the caudal rami included, 
and are especially distinguished by the extraordi- 
narily slender and prolonged flagellum, consisting of 
numerous short joints, which is usually directed 
straight backwards. On the other hand, the peduncle 
(see Pl. IV, fig. 2) distinguishes itself only little 
from the same part in the female. Still its last” 
joint is somewhat thicker, and is without the long 
plumose bristles which, in the female, issue from the 
extremity; in place of them there are only found a 
few very fine hairs. ?, 
The mandibles and upper lip exhibit exactly 
the same appearance as in the female. . 
The 2 pairs of maxille also (fig. 3 and 4) are 
constructed in the same manner as in the female; 
but both pairs are relatively smaller, and have, 
especially, the masticatory lobes much more faintly 
developed and only furnished with extremely small 
simple bristles. 
The branchial feet (fig. 5) have the stem-proper, 
or endopodite, considerably fainter developed than 
in the female, and scarcely reaching beyond the exo- 
podite. The bristles attached to it are also shorter 
and all alike in appearance, without those attached 
to the point distinguishing themselves by any re- 
markable length. “In contrast herewith the exopo- 
dite as well as the epipodite are particularly large, 
and their gill-structure more distinguished than in 
the female. , 
The swimming feet of the posterior division of 
the body are altogether more powerfully developed
