Hvad de forskjellige Lemmer angaar, saa viser 
de til det forreste Afsnit af Legemet horende neppe 
nogen vesentlig Forskjel fra samme hos Hunnen, 
skjondt maaske Iste Par Folere er noget storre og 
rigeligere forsynede med Lugtepapiller. Derimod 
bemerkes flere characteristiske Eiendommeligheder 
ved de til det bagerste Afsnit horende Lemmer eller 
Branchialfodderne. For det forste er deres Tal her 
constant et ringere, nemlig kun 10 Par ialt, og der- 
nest er iste Par meget uligt samme hos Hunnen, 
idet det er omdannet til et Par serdeles kraftige 
Griberedskaber, hvormed Hannen under Parringen 
fastholder Hunnens Skal (se Tab. XX, Fig. 6). 
Fig. 7 fremstiller en Fod af dette Par, seet fra den 
forreste Flade, og Fig. 8 det ydre Parti af samme 
noget sterkere forstorret. Som det vil sees, er 
Exopoditen og Epipoditen, ligesom ogsaa Coxal- 
lappen, noget neer af samme Udseende som hos Hun- 
nen. Derimod er det terminale Afsnit af Endopo- 
diten meget sterkt modificeret og omdannet til en 
med den proximale Del bevegeligt forbunden Haand, 
ligesom de til dette Afsnit horende Enditer er eien- 
dommeligt omformede. Selve Haanden er nesten 
qvadratisk af Form, med den indre Kant, eller Pal- 
men, sterkt buet og bevebnet med en Rad af 9 
meget sterke, noget pladeformige Pigge, mellem 
hvilke rager frem stive Borster. Den yderste Endit 
er omformet til en kraftig, leformigt indadkrummet 
Klo, der udgaar med en noget udvidet Basis fra 
Enden af Haanden og kan ved Hjelp af en Del 
Muskler boies ind mod de ovenomtalte Pigge. Ved 
Roden af denne Klo udgaar et andet Appendix, der 
sedvanligvis ogsaa er indadkrummet, men ender i 
en stump, med lange Borster besat Spids og som 
synes at forestille den nestsidste omformede Endit. 
Lengere indad, mellem Kloen og de ovenomtalte 
Pigge er endelig feestet nok et Appendix, der er lige 
nedadrettet og har Formen af et ovalt Blad, tet 
besat med Borster. Dette Blad synes at repraesen- 
tere den 3die sidste Endit. Fra den proximale Del 
af Endopoditen udgaar indad en enkelt bred plade- 
formig Udvidning kantet med en dobbelt Rad af 
lange Borster, og rimeligvis fremkommen ved en 
Sammensmeltning af de 2 inderste Enditer. 
2det Fodpar (Fig. 9) er fuldkommen normalt 
bygget, men skiller sig dog ved en noiere Under- 
segelse fra samme hos Hunnen ved den nestsidste 
Endits Beveebning (se Fig. 9 a). Foruden de seed- 
vanlige Borster findes der nemlig langs den indre 
Kant af denne Endit en Rekke af eiendommelige, 
i Enden tvedelte Torne, der successivt tiltager i 
Lengde mod Spidsen. Den yderste af disse Torne 
(Fig. 9,b) har foruden de 2 Endespidser i den indre 
Kant 4 korte Smaateender. 
De folgende 6 Par stemmer i alt viéeondiiligt 
The limbs belonging to the anterior section of 
the body exhibit scarcely any essential difference 
to those in the female, although the first pair of 
antenne are perhaps rather larger and more abun- 
dantly provided with olfactory papille. On the 
other hand, several characteristic peculiarities may 
be noticed in the jimbs belonging to the posterior 
section, or the branchial legs. In the first place 
their number is invariably smaller, namely, only 10 
pairs in all; and in the second place, the 1st pair 
is very unlike that in the female, being converted 
into a pair of exceedingly powerful prehensile organs, 
by. means of which the male, during copulation, 
grasps the shell of the female (see Pl. XX, fig. 6). 
Fig. 7 represents one leg of this pair seen from the 
front, and fig. 8, the outer part of the same, mag- 
nified rather more highly. As will be seen, the 
exopodite, the epipodite, and the coxal lobes are 
nearly of the same appearance as in the female. 
The terminal section of the endopodite, on the other 
hand, is very greatly modified and converted into — 
a hand, movably connected with the proximal part, 
the endites belonging to this section also being 
peculiarly transformed. The hand itself is almost 
quadratic in shape, with the inner edge, or palm, 
much arched and armed with a row of 9 very 
strong, somewhat lamellar spines, between which 
project stiff bristles. The outermost endite is trans- 
formed into a powerful, falciform, inward-curving 
claw, which issues with a somewhat expanded base 
from the end of the hand, and can, by the aid of 
certain muscles, be bent in towards the above- 
mentioned spines. At the root of this claw, issues 
another appendage, which is also usually bent in- 
wards, but ends in a blunt point clothed with long 
bristles, and seems to represent the penultimate 
transformed endite. Farther in between the claw 
and the above-mentioned spines, there is attached 
yet another appendage, which points straight down- 
wards, and is in the shape of an oval lamina, 
closely set with bristles. This lamina seems to — 
represent the antepenultimate endite. From the 
proximal part of the endopodite there runs inwards 
a single, broad, lamellar expansion edged with a 
double row of long bristles, and probably produced 
by a coalescence of the two innermost endites. 
The 2nd pair of legs (fig. 9) is quite normal in 
structure, but on a closer examination, is distin- 
guished from that of the female by the equipment 
of the penultimate endite (see fig. 9a). In addition 
to the usual bristles, there is also, along the inner 
edge of this endite, a row of peculiar bifid spines, 
which successively increase in length towards the 
point. The outermost of these spines (fig. 9, b) has, 
in addition to the two terminal points, 4 short den- 
ticles on the inner margin. 
The succeeding 6 pairs agree in all essential
