(se Tab. XVI, Fig. 3) Formen af nedadrettede aflange, 
noget buede og uregelmessigt fligede Plader, hvis 
convexe Side vender fortil, den concave bagtil, og 
som i Kanterne er rigeligt borstebesatte. Man kan 
paa dem adskille de samme 3 Hoveddele som hos 
andre Branchiopoder, nemlig Endopodit, Exopodit og 
' Epipodit. Endopoditen, eller den egentlige Stamme, 
har ved Basis indad en meget tydeligt. sondret 
Coxallap (mx) af temmelig compliceret Bygning (se 
Fig.4). Den er noget skraat indadrettet, af stumpt 
konisk Form og meget rigeligt forsynet med Bor- 
ster. Ved Spidsen har den 2 korte Pigge, og en lig- 
nende Pig findes ogsaa paa den indre Side. 
denne sidste Pig strekker sig en noget skraat 
lobende Rad af lange, leformigt indad krummede 
Borster, der alle er tydeligt 2-leddede og fint cili- 
erede. En anden Rad af cilierede Borster strekker 
sig langs den ydre Kant af Coxallappen, men disse 
Borster er ikke leformigt krummede og aftager hur- 
tigt i Lengde mod Spidsen. Umiddelbart ovenfor 
dem udgaar fra Yderkanten en noget stzrkere, 
skraat indadrettet Borste. Den indre Kant af En- 
dopoditen er ved smaa Indsnit delt i 4 korte og 
brede Lappe (Enditer), der berer en dobbelt Rad af 
fint cilierede Borster, hvoraf de i den ene er ser- 
deles lange, tydeligt 2-leddede og bagudboiede. Den 
yderste af disse Lappe er noget mere fremspringende 
end de ovrige, og til dens ydre Side er articuleret 
en smal tungeformig Lamelle, rundt om besat med 
cilierede Borster. Denne Lamelle forestiller den 
yderste (Ste) Endit, eller Endopoditens Endeled, det 
eneste tydeligt begreendsede Led paa Foden. Epi- 
poditen (ep) har Formen af et aflangt ovalt, noget 
sekformigt Appendix, uden ethvert Spor af Borster. 
Den er festet til Ydersiden af Endopoditen i en 
kort Afstand fra dennes Basis og rettet lige opad 
over Siderne af Kroppen (se Tab, XV, Fig. 1). 
Exopoditen (ex), der udspringer med en bred Basis 
ligeledes fra Ydersiden af Endopoditen og umiddel- 
bart nedenfor Epipoditen, er af betydelig Storrelse 
og delt i 2 smale i forskjellig Retning udgaaende 
Lappe, en ventral og en dorsal. Den ventrale Lap 
rekker omtrent til Spidsen af Endopoditens Ende- 
lamelle, og er ligesom denne rundtom kantet med 
cilierede Borster. Den dorsale Lap (ex!) er betyde- 
lig mindre end den ventrale, neppe overragende 
Epipoditen, og er berstebesat alene i den ydre Kant. 
Paa 9de til 11te Fodpar er imidlertid hos fuldt ud- 
viklede Individer (se Tab. XV, Fig. 1) denne Lap 
udtrukket til en meget lang traadformig Fortsats, 
der rager op i Skallens dorsale Cavitet, hvor den 
tjener til Feste for den her sig ansamlende Aig- 
masse. 23de eller sidste Fodpar (Fig. 5, 6) skiller 
sig i visse Henseender kjendeligt fra de ovrige. Det 
er serdeles lidet og har Endopoditen ganske kort, 
med kun 3 Lappe indad, foruden Coxallappen. Bor-

difficult to count.. They all (see Pl. XVI, fig. 3) 
have the shape of down-pointing, oblong, somewhat 
curved, and irregularly lobed lamin, whose convex 
side turns to the front, the concave to the back, 
and whose edges are thickly clothed with bristles. 
The same 3 principal parts can be distinguished in 
them as in other Branchiopods, namely, endopodite, 
exopodite and epipodite, The endopodite, or stem 
proper, has on the inner side of the base a very 
distinctly-defined coxal lobe of rather complicated — 
structure (see fig. 4). It is directed rather obliquely 
inwards, is of a bluntly conical shape, and abun- 
dantly provided with bristles. At the point it has 
two short spines, and a similar spine is also found 
on the inner side. From this last-mentioned spine, 
runs a rather oblique row of long, falciformly 
incurved bristles, all distinctly 2-jointed and finely 
ciliated. Another row of ciliated bristles runs along 
the outer edge of the coxal lobe, but these are not 
falciformly curved, and they rapidly decrease in length 
towards the point. Immediately above them, there 
issues from the outer edge a somewhat stronger 
bristle, directed obliquely inwards. The inner edge 
of the endopodite is divided by small indentations 
into 4 short, broad lobes (endites) carrying a double 
row of finely ciliated bristles, which in one row are 
particularly long, distinctly 2-jointed, and bent back- 
wards. The outermost of these lobes is rather more 
projecting than the others, and to its outer side is 
articulated a narrow lingular lamella, edged all 
round with ciliated bristles. This lamella represents 
the outermost (5th) endite, or the terminal joint of 
the endopodite, the only distinctly defined joint in 
the leg. The epipodite (ep) is in the shape of an 
oblong oval, somewhat sac-like appendage, with no 
trace of bristles. It is attached to the outer side 
of the endopodite at a short distance from its base, 
and is directed straight upwards over the sides of 
the body (see Pl. XV, fig. 1). The exopodite (ex), 
which issues with a broad base also from the outer 
side of the endopodite, and immediately below the 
epipodite, is of considerable size, and is divided into 
2 narrow lobes, one ventral and one dorsal, pro- 
jecting in opposite directions. The ventral lobe 
reaches almost to the point of the terminal lamella 
of the endopodite, and is likewise edged all round 
with ciliated bristles. The dorsal lobe (ex') is con- 
siderably smaller than the ventral, scarcely reaching 
beyond the epipodite, and is edged with bristles 
only on the outer margin. On the 9th, 10th and 
11th pairs of legs in fully-developed specimens, how- 
ever (see Pl. XV, fig. 1), this lobe is drawn out to 
a very long filiform projection, which extends up 
into the dorsal cavity of the shell, where it serves 
as an attachment for the accumulated egg-mass 
there. The 23rd or last pair of legs (figs. 5 and 6) 
is conspicuously distinguished in certain respects
