Af Lemmer Andes hos Hunnen kun de 4 Par Gang- 
fodder. Hertil komrner imidlertid hos Hannen et 5tc Par, 
fra Bugsiden af Hovedsegraentet udgaaende Lemmer, de 
saakaldte falske Fodder (sc Fig. 1 f). Derimod er der hos 
fuldt udviklede Dvr intetsomhelst Spor hverken afSaxlem- 
mer eller Folere at opdage. 
Gangfpdderne (Fig. 1 c) er af temmelig plump og 
kraftig Bygning, noget kortere end Legemet og bestaaende 
af det smdvanlige Antal (8) Led. Af de 3 Hofteled er 
det lste stprst og temmelig bredt, isser paa sidste Fodpar 
(se Fig. 1), hvor dot ligger tmt ind mod Halesegmentet, 
der herved viser sig ligesom indkilet mellem Basis af dette 
Fodpar. Laarleddet er omtrent saa langt som de 2 sidste 
Hofteled tilsammen og af en noget uregelnnessig Form, 
med den indre Kant vinkelformigt udbuet paa Midten og 
den ydre eller 0vre Kant gaaende ud ved Enden af Led- 
det i 2 jevnsides stillcde, mere eller raindre tydelige koniske 
Fremspring. lste Ltegled er lidt kortere end Laarleddet, 
staerkt indknebet ved Roden og gaar ved Enden paa den 
ovre Side ud i 2 lignende, men noget mindre Fremspring. 
2det Lsegled er betydclig mindre, noget skraat afskaaret i 
Enden og viser Antydning til lignende Fremspring som 
paa de 2 foregaaende Led. Tarsalleddet (se ogsaa Fig. 
1 d) er meget kort, af trekantet Form og paa Ydersiden 
nsesten ganske dsekket af foregaaende Led; dets indre Kant 
er bueformigt boiet og, ligesom en Del af foregaaende Leds 
Inderkant, tret besat med korte, tornformige Borster. Fod- 
leddet er mere end 3 Gange leengere end Tarsalleddet, 
men betydclig smalere, temmelig staerkt krummet og over- 
alt omtrent af ens Brede. Inderkanten er noget concav 
og tret besat med lignende korte Borter som paa Tarsal- 
leddet og ender med en liden smalt afrundet Lap. Ende- 
kloen er srerdeles kraftig, mere end halvt saa lang som 
Fodleddet og af hornbrun, ofte rues ten sort Farve. Den 
er i sit ydre Parti jevnt krummet og ender med en syl- 
skarp Spids. Af Bikloer er der ikke det mindste Spor at 
opdage. 
De falske Fodder Andes, som anfort, alene hos Han- 
nerne, og deres Function synes her udelukkende kun at 
vjere den at fastholde den ydre iEgmasse. De er (se Fig. 
1 f) frestede til hver Side under den forreste Del af Ho- 
vedsegmentet til et lidet afrundet Fremspring, og er i 
Sammenligning med samme hos andre Pycnogonideer meget 
smaa og svage, idet de knapt opnaar 1 / J , af Legemets 
Lrengde. Yed noiere Undorsogelse (Fig. 1 g) viser de sig 
at bestaa af det samme Antal Led som Gangfodderne og 
ender som disse med en kraftig Klo ; men Lrengdeforholdet 
mellem Leddene er meget forskjelligt. De 4 forste Led er 
forholdsvis meget smaa og nsesten af ens Lrengde, hvori- 
mod de folgende 4 er noget storre, navnlig 5te og 6te. 
Langs den indre Kant af Leddene bemrerkes nogle meget 
smaa og uregelmressigt fordelte Tomer af ganske simpel 
Form (Fig. 1 h). Endekloen er omtrent saa lang som det 
usual triangular form, though wanting distinctly developed 
lip-plates. 
Of limbs, occur in the female only the 4 pairs of am- 
bulatory legs. The male however is furnished with a 5th 
pair, the so-called false legs (see Ag. 1 f), issuing from the 
ventral side of the cephalic segment. On the other hand, 
in fully developed animals no trace can be detected of 
I either chclifori or palps. 
The ambulatory legs (Ag. 1 c) are rather clumsy and 
powerful in structure, somewhat shorter than the body, 
and composed of the usual number (8) of joints. Of the 
3 coxal joints, the Arst is the largest, and rather broad, 
more especially on the last pair of legs (see Ag. 1), where 
it lies close up to the caudal segment, which has thus the 
appearance of being wedged in between the base of this 
pair of legs. The femoral joint is about as long as the 2 
last coxal joints taken together and of a somewhat irregu- 
lar form, with the inner margin bent out angularly in the 
middle and the outer or upper margin running at tire ex- 
tremity of the joint into 2 parallel, more or less distinctly 
conic projections. The I st tibial joint is a trifle shorter 
than the femoral, very considerably instrictod at the base, 
and divides at the extremity on the upper side into 2 
similar, but somewhat smaller projections. The 2nd tibial 
joint is a good deal smaller, cut off somewhat obliquely at 
the extremity, and indicates the occurrence of similar pro- 
jections, as in the 2 preceding joints. The tarsus (see Ag. 
1 d) is very short, triangular in form, and on the outer side 
well-nigh wholly covered by the preceding joint; its inner 
margin is arched arid, as with part of the inner margin of 
preceding joint, densely beset with short spiculiform bristles. 
The propodus has more than 3 times the length of the 
tarsus, but is considerably narrower, very much curved, and 
everywhere of well-nigh the same breadth. The inner margin 
is a little concave, densely beset with short bristles similar 
to those on the tarsus, and terminates in a small, narrowly 
rounded lobe. The terminal claw is remarkably powerful, 
more than half as long as the tarsus, and of a horny 
brown, often well-nigh black colour. It has the outer part 
uniformly curved and terminates in a sharp point. Of 
auxiliary claws not a trace can be detected. 
The false feet occur, as stated above, in the males 
only: and their function would seem to be exclusively that 
of grasping the outer egg-mass. They are afflxecl (see 
Ag. 1 fj on either side, under the foremost part of the 
cephalic segment, to a small rounded projection,, and are, 
as compared with those limits in other Pycnogonids, very 
small and feeble, attaining scarcely one-fourth of the length 
of the body. On closer examination (Ag. 1 g), they are 
found to have the same .number of joints as the ambu- 
latory legs, and, like those limbs, they terminate in a powerful 
claw; but as to length, the proportion between the joints is 
rather different. The 4 Arst joints are comparatively very 
small and almost equal in length, whereas the following 
4 are somewhat larger, in particular the 5th and 6th. 
Along the inner margin of the joints extend a few very 
small and irregularly distributed spines of quite a simple
