mellem hvilke deres ydre Del feeder frem, er af den stcd- 
vanlige smsekre Bygning og kan strmkkes med hele Skaftets 
sidste Led foran 0inene. 
2 det Par Foleres Basaklel riser udad en sterk, for- 
tilrettet og i den indre Kant tandet Torn og indenfor deune 
et nsesten dobbelt saa langt, lancetformigt, bevtegeligt Ved- 
haeng, der svarer til Bladet bos Macrureme. Dette Ved- 
haeng overrager med sin Spids 0inene og er besat med 
spredte Haar. Den traadformige rfvpbe er omtrent af Lege- 
mets Lamgde og delt i talrige korte Led. 
Pangarmene er meget ulige udviklede og, som altid 
Tilfseldet er hos Arterne af den egentlige Sltegt Eupagurus, 
den hoi re stprst. Den er omtrent af liele Legemets Lsengde 
og af en sserdeles kraftig Bygning. De 3 fprste Led er, 
naar Dyret sees ovenfra, ganske skjulte under Forkroppen. 
4de Led er af prismatisk Form, indad nassten plant og 
udvidet mod Enden, hvor det er forsynet med nogle spredte 
Tomer og Bprster. 5te Led eller Vristen er omtrent al 
samme Storrelse og af nsesten trekantet Form. Dets 0vre 
Flade er uoget hvadvet og torsynet med talrige tornformige 
lvnuder, som mod den i ndre Kant bliver storre og ordner 
sig i mere eller miudre tydebge Lamgderader ; mellem Tor- 
nene staar tette Borsteknipper. Haanden (se ogsaa Fig. 9) 
er sserdeles kraftig, af bredt oval Form, uoget aifladet og 
lidt laengere end Vristen. Dens ovre Flade er meget ujevn 
og viser 3 tydeligt markerede Lmngdekjoler, bvoraf de to 
iiultager Sidekanterne og er forsynede med skarpe Saug- 
takker, medens den 3die lober langs ad Midteu og er mere 
stumpt afrundet samt forsynet med mindre knudeformige 
Forhoininger, som dog bagtil del vis antager Formen af 
spidse Torner. Mellem Kjolerne er Overtladen tydelig ind- 
bulet og her kun forsynet med adspredte stumpe Knuder. 
Fingrene er noget kortere end Palmen, brede og noget 
affladede samt jevnt krummede mod S])idsen. De er som 
den ovrige Del af Haanden besatte med Borsteknipper og 
viser i den indre Kant uregelmsessige storre og mindre 
Knuder. Haandens ydre Kjol fortsretter sig som en saug- 
takket Kam langs ad den ubevsegelige Finger lige til dens 
Spids, og ogsaa den mediane Kjol lader sig delvis forfplge 
langs ad den indre Kant af Fingeren. Den bevtegelige 
Finger er saavel paa sin ovre Flade som i Kanten forsynet 
med tydelige tornformige Knuder. 
Den venstre Fangarm er, som ovenfor antydet, be- 
tydelig baade kortere og svagere bygget end don lioire. 
Vristen er ogsaa her paa sin ovre Flade besat med spidse 
Torner, der dog er langt fserre i Antal. Haanden (se Fig. 
10) er ligesom Vristen tet haaret og af aflang oval Form, 
indad uden Spor af Torner, udad derimod forsynet med 
en saugtakket Kam, og langs Midten af den ovre Flade 
med en bagtil sterlet fremspringende tandet Kjol. Fingrene 
neath the eyes, between which their exterior portion projects, 
exhibit the usual slender structure, and admit of being 
exsertod, along with the whole of the last segment of the 
peduncle, in front of the eyes. 
The basal portion of the 2nd pair of antennae ex- 
hibits exteriorly a stout, anteriorly directed, and, along the 
inner margin, dentate spine, on the inner side of which is 
an almost double as long, lanceolate, moveable appendage, 
corresponding to the scale in the Macnira. This appen- 
dage projects with its point beyond the eyes, and is beset 
with scattered hairs. The filiform flagellum is about of 
the same length as the body, and divided into numerous 
short segments. 
The chelipeds are very unequally developed, and, as 
is always the case in species of the true genus Eupagurus, 
the right one is the larger; it attains about the length of 
the whole body, and has an extremely powerful structure. 
The 3 anterior segments are, when the animal is viewed 
from above, wholly concealed beneath the cephalo-thorax; the 
4th segment is prismatic in form, inward almost plane, 
and furnished toward the extremity with a few scattered 
spines and bristles; the 5th segment, or wrist, is about of 
the same size and well-nigh triangular in form; its upper 
surface is somewhat arcuate and provided with numerous 
spiniform protuberances, which, toward the inner margin, 
gradually increase, and are arranged in more or less dis- 
tinct longitudinal series; between the spines occur closely 
disposed bunches of bristles; the hand (see also tig. 9) is 
exceedingly powerful, broadly ovate in form, somewhat bev- 
elled, and a trifle longer than the wrist; its upper surface 
is very uneven and exhibits 3 distinctly marked longitudinal 
car i rue. two of which occupy the lateral margins, and are 
distinctly serrate throughout, whereas the 3rd carina runs 
along the middle, and is more obtusely rounded, as also 
beset with small tuberculiform protuberances, which, however, 
in places, assume the form of sharp spines; between the 
carina 1 , the surface is distinctly hollowed out, and fur- 
nished there with only a few scattered knobs; the fingers 
are somewhat shorter than the palm, broad and slightly 
bevelled, as also uniformly curving towards the point; like 
the remaining portion of the hand, they are beset with 
bunches of bristles, and exhibit along the inner margin 
irregular-shaped tubercles, varying in size; the exterior 
carina of the hand is produced as a serrate comb along 
the immovable finger to its very point, and the median 
carina may be partly traced along the inner margin of the 
finger; the moveable finger is provided, both on its upper 
surface and along the margin, with distinctly spiniform 
tubercles. 
The left cheliped is, as stated above, considerably 
shorter, and exhibits besides a much more slender form than 
the right; the wrist, too, is beset over its upper surface with 
acute spines, which, however, are very considerably less 
numerous; the hand (see fig. 10) is, like the wrist, densely 
ciliated and oblongo-ovate in form, exhibiting interiorly not 
a trace of spines, but exteriorly furnished with a serrate 
comb, and having along the middle of its upper surface
