Inderkanten. Begge Fingre er stserkt chitiniserede og’ dei- 
for af mark hornbrun Farve, Hos yngre Individer (— P- 
discoidea, K raver) viser disse Lemmer (se Fig. 3 h) et tem- 
melig afvigende Udseende og - er idetbele betydehg s\ageie 
udvildede end hos fuldvoxne Exemplarer. Navnlig er Saxen 
meget forskjellig. Den er nemlig paa langt ncer xkke saa 
stserkt opsvnlmet og af teimnelig regelmsessig oval b orm, 
med Fingrene udstrakte i Palmens Axe saint endende i en 
fin, noget indbpiet Spids. Inderkanten af begge Fingre er 
desuden fint tandet i liele Lsengdon, og den ubevsegelige 
Finger mangier ethvert Spor at det stserke knudeformige 
Fremspring, som forefindes her hos fuldvoxne Individer. 
De falske Fodder, der er f'sestede noget ventralt, ne- 
denunder Forkanten af de forrcste Sidefovtsatser, er torholds- 
vis korte, navnlig hos Hunnen. Hos Ilannen er do vistnok 
noget hong ere (se Fig. 3 a), men opnaar dog neppe Lege- 
mets Lsengde. 5te Led har hos Ilannen ved Lnden en lig- 
nende fligformig Fortsats som hos foregaaende Slsegt. De 
4 yd re Led (Fig. 3 d) aftager successivt i Storrelse og er 
langs Inderkanten forsynede med en Del teimnelig uregel- 
msessigt ordnedc Tomer uden Sidetsender (Fig. ■> e). Det 
forholdsvis lille sidste Led har kun 2 saadanne og bserer i 
Spidsen en vel udviklot Endeklo, der i Inderkanten ei tint 
tandet. 
Gangfeddeme (se Fig. 3, 3 f) er af ussedvaulig kort 
og robust Form, neppe mere end dobbelt saa lange som 
Kroppen, og bevsebnede med talrige koniske, i Kanterne 
fint baarede, pigformige Fortsatser, liver bserende i Spidsen 
en stiv Borste. Disse Fortsatser er paa de 2 Lscglod tem- 
melig regelmsessigt ordnede i 3 Raikker, hvoraf de i den 
yd re Kant fsestede navnlig er stserkt udvildede, givende 
Faddernc her et regelmsessigt saugtakket Udseende (se Fig. 
3f). Paa Laarleddet or de noget mere uregelmsessigt ord- 
nede, og paa Hoftepartiet grupperer de sig isser om Enden 
af Leddene. Som hos foregaaende Slsegt er Laarleddet bos 
fuldt udvildede H miner (Fig. 3) stserkt opsvul.net paa Grand 
af do sig i dets Indre udviklende Jig, der dog her aldrig 
opnaar en saa betydelig Storrelse. Hos Hannernc er dette 
Led (se Fig. 3 f) adskilligt smalere, noget mdsnaret paa 
Midten og desuden udmserket ved 2 stserke afrundede Knu- 
der i Inderkanten; en lignende Knude Andes ogsaa paa et- 
hvert af de 2 falgende Led nser Basis. Angaaende Ledde- 
nes indbyrdes Lsengdeforhold, saa er Laarleddet omtrcnt saa 
langt som de 3 Hofteled tilsammen; IsteLsegled er omtrent 
af Laar led dets Lsengde, medens 2det er kjendebg lamgere 
og smalere. Tarsalleddet er meget Met, dog iorboldsvis 
storre end hos foregaaende Slsegt, af triangular form, med 
Inderkanten skydende ud i en afrundet, med korte Tomer 
besat Lap. Fodleddet er kraftigt udviklet og temmelig 
stserkt krummet; det er langs Inderkanten bevsebnet med 
omkring 8 — 10 stserke Torner, livoraf de 4 bagerste er stent 
Endekloen er stserkt cliitiniseret, noget kortere end Fod- 
leddet og jevnt krummet. Af Bikloer er der lkke det 
mindste Spor at opdage.

projection in the middle of the inner margin. Both fingers 
are highly chitinized and therefore of a dark horny brown 
colour. In young specimens (— P. discoidea, K rover) these 
limbs exhibit a rather deviating appearance (see fig. 3 h) 
and are, on the whole, much less developed than in tull- 
grown examples. The chela especially is very different. 
It does not occur nearly so tumid and has a rather 
regular oval form, with the fingers extended in the axis 
of the palm and ending in a fine, somewhat incurvate 
point. The inner edge of both fingers, moreover, is deli- 
cately dentated throughout its whole length, and the im- 
mobile finger fails to exhibit any trace ol the prominent 
nodular projection, found here in adult specimens. 
The false legs, which are attached somewhat ventrally 
underneath the anterior edge of the foremost lateral processes, 
are comparatively short, more especially in the female. In the 
male they are, indeed, somewhat longer (see fig. 3 a), hut hardly 
attain the length of the body. The 5th joint in the male 
has, at the extremity, a lobular process similar to that in the 
preceding genus. The 4 outer joints (fig. 3 d) diminish 
successively in size, and are furnished along the inner edge 
with a number of rather irregularly disposed spines without 
lateral teeth (fig. 3 e). The last, comparatively small joint 
has only 2 such spines, and hears at the point a well de- 
veloped terminal claw, finely dentated on the inner edge. 
The ambulatory legs (see fig. 3, 3 f) are remarkably 
short and robust in form, scarcely more than twice as long as 
the body, and aimed with numerous conical spiniform projec- 
tions delicately ciliated on the- edges, each bearing at the tip 
a stiff bristle. On the 2 tibial joints these projections are 
rather regularly arranged in 3 series, those attached to the 
outer edge being, in particular, strongly developed, impairing 
to the legs here a regular serrate appearance (see fig. 3 f). 
On the femoral joint they are somewhat less regularly disposed, 
and on the coxal part they group themselves mostly about 
the extremity of the joints. As in the preceding genus, the 
femoral joint in fully developed females (fig. 3) is very ranch 
swollen, owing to the eggs in course of developement within, 
which do not, however, attain here any considerable size. In 
the males this joint (see fig. 3 f) is much more slender, some- 
what constricted in the middle, and distinguished, moreover, 
by 2 prominent rounded protuberances on the inner edge; 
a similar protuberance is also found on each of the 2 suc- 
ceeding joints near the base. Respecting the mutual longi- 
tudinal relation of the joints, the femoral joint is about as 
long as the 3 coxal joints taken together; the 1st tibial joint is 
about the length of the femoral joint, whereas the 2nd is appre- 
ciably longer and narrower, r lhe tarsal joint is very small, 
yet comparatively larger than in the preceding genus, trian- 
gular in form, with the inner edge projecting as a rounded 
lobe, beset with short spines. The propodal joint is powerfully 
developed and rather strongly curved; it is armed along 
the inner edge with about 8 — 10 strong spines, the 4 hind- 
most of which are largest. The terminal claw is highly chi- 
tinized, somewhat shorter than the propodal joint, and evenly 
l curved. Of auxiliary claws not a trace can he detected.
