Led og retter sig lige fortil. er af en meget smal, linear 
Form og i Enden utydeligt leddet og borstebesat; Epigna- 
theu er af samme Beskaffenhed som paa foregaaende Par, 
men af nsesten cirkelrund Form. Bag denne udgaar fra 
Roddelens ydre Bide en smal tungeformig Flig. som ogsaa 
forefindes paa det folgende Par saint paa samtlige F odder. 
3die Par Kjsevefpdder (Fig. 16) er stterkt forlsengede, 
fodformige og rsekker fortilstrakte omtrent til Spidsen ai 
2 det Par Foleres Blad. Af Stammens 5 Led er det Bdie 
storst og mindre skarpt adskilt fra det foregaaende, samt 
temmelig stasrkt krummet. Sidste Led er ikke meget kortere, 
men staerkt afsmalnende mod Enden, der er udtrukken i 
en sylformig Spids. Det er ligesom de foregaaende Led 
besat med trntte Borsteknipper, som navnlig i den indre 
Kant er stserkt udviklede, hvorimod egentlige Tomer mangier. 
Til Ydersiden af Stammens 2det Led er fsestet en 
vel udviklet Exognath, paa. hvilken kan adskilles en smalt 
cylindrisk Basaldel og en noget sammentrykt, maugeleddet 
og med lange Fjaerbprster besat Endedel. Den hele Exo- 
gnaths Lsengde er lige udstrakt omtrent at Stammens 
Lsengde. 
Endelig er til Ydersiden af Stammens Rodled fsestet 
en oval eller elliptisk Epignath, der i hoi Grad udmserker 
sig derved. at den bar antaget Beskaffenheden af en virkelig 
Gjelle, idet der fra dens ydre Flade liar life vet sig 8 -9 
tydelige bladformige Tvaerfolder. 
Samtlige Fodder bar fsestet til Ydersiden af 2det Led 
en vel udviklet Svommegren (Exopodit) ligesom bos Schi- 
zopoderne og svarende til den saakaldte Exognath paa 
Munddelene. 
De to forreste Par er kortest og som bos Pasiphae 
forsynede med Saxe; de 3 bagestePar er derimod simple i 
Enden. 
lste Fodpar (Fig. 17) er knapt saa langt som sidste 
Par Kjsevefodder og af forholdsvis svag Bygning. Af Led- 
dene er det 4de storst og bengere end de 3 foregaaende 
tilsammen. 5te Led danner med dette i Regelen en stserk 
knaeformig Boining og er knapt */s saa Lngt. 6te Led 
eller Haanden er kun lidet tykkere end det foregaaende 
Led og indtager omtrent '/.j at Fodens .Lamgde. Fingrene 
er, sammenlignet med samme bos Pasiphae, meget korte, 
neppe lialvt saa lange som Palrnen, temmelig tynde og i 
Spidsen svagt krummede (se ogsaa Fig. 18). Alle Led er 
mere eller mindre tet borstebesatte, navnlig i den indre 
Kant; dog er Borsterne paa selve Haanden meget korte. 
Svommegrenen er stserkt udviklet og rsekker lige for- 
tilstrakt ud over 4de Led. Dens Bygning stemmer forov- 
rigt fuldkommen overens med Exognatben paa sidste Par 
Kjsevefodder.

The exognath, attached to the outer side of the 2nd joint 
of the stem and protending straight forward, has an ex- 
ceedingly slender, linear form, and at the end is indis- 
tinctly articulated, and beset with bristles; the epignath 
exhibits a structure similar to that in the preceding pair, but 
a well-nigh circular form. Posterior to the latter, proceed 
from the outer side of the basal part a narrow, linguiform 
lobule, which also occurs on the succeeding pair, arid on 
all of the legs. 
The 3rd pair of maxillipeds (fig. 16) are greatly pro- 
duced, pediform, and reach, extended anteriorly, about 
to the point of the scale of the 2nd pair of antennae. Of 
the 5 joints of the stem, the 3rd is the largest, and less 
distinctly separated from the preceding, as also a good deal 
curved. The terminal joint is not much shorter, tapers 
rapidly toward the extremity, which is drawn out to an 
awl-shaped point. Like the preceding joints, it is beset 
with dense fascicles of bristles, which, more particularly 
on the inner margin, are strongly developed; true spines, 
however, do not occur. 
To the outer side of the 2nd joint of the stem is 
attached a well-developed exognath, on which can be dis- 
tinguished a narrow, cylindric basal portion and a somewhat 
compressed, multiarticulate terminal part, beset with long, 
plumose bristles. The whole length of the exognath, when 
fully extended, equals about one-third of the length of the 
stem. 
Finally, on the outer side of the basal joint of the 
stem is attached an oval or elliptic epignath, strikingly 
distinguished by having assumed the character of a true 
brancliia, 8 or 9 distinct transverse folds rising from its 
outer surface. 
All of the legs have a well-developed natatory branch 
(exopodite) attached to the outer side of the 2nd joint, as 
in the Schizopods, corresponding to the so-called exognath 
on the oral appendages. 
The two anterior pairs are shortest, and, as in Pasiphae. 
furnished with chela; the three posterior pairs are, on the 
other hand, simple at the extremity. 
The 1st pair of legs (fig. 17) are scarcely as loug as 
the last pair of maxillipeds, and comparatively feeble in 
structure. Of the joints, the 4th is the largest, and longer 
than the three preceding ones taken together. The 5th 
joint forms along with the 4th, as a rule, a strong, geniculate 
bend, and is hardly one-third as long as the latter. The 6th 
joint, or hand, is but little thicker than the preceding joint, 
and measures about one-fourth of the length of the leg. 
The fingers, as compared with those in Pasiphae, are ex- 
ceedingly short, scarcely half as long as the palm, somewhat 
I slender, and at the point slightly curved (see, too, fig. 18). 
All of the joints are more or less densely beset with bristles, 
in particular along the inner margin; the bristles on the 
hand itself, however, are very short. 
The natatory branch is powerfully developed, and 
reaches, anteriorly extended, beyond the 4th joint. For 
the rest, its structure perfectly agrees with that of the 
exognath on the last pair of maxillipeds.
