korte og tsette Haar. Fingrene er nogct kortere end Pal- 
men, konisk tilspidsede og bar Spidserne noget boicde. In- 
derkanten af begge er forsynet med en tset Rad af smaa 
Tsender og slutter tad saminen, naar Saxen er lukket, idet 
de omhandlede Tsender griber ind mellem binanden. Af 
Fingrene er den bevsegelige noget lsengere end den ubevse- 
gelige og mindre bred ved Basis. 
Folerne ("Fig. 1 e), der udspringer noget nedenfor Sax- 
lemmerne til liver Side af Snabelens Basis (se Fig. 1 a), 
er lidt kortere end bine og meget spinklere. De bestaar, 
som bos alle Nympbonider, af 5 Led, bvoraf det lste er 
meget lidet. De 2 derpaa folgende Led er forbengede og 
indbyrdes omtrent af samrae Lsengde, det yderste af dem 
noget fortvkket mod Enden og besat i begge Kanter med 
en Del korte Burster. De 2 sidste Led danner tilsammen 
en temmelig bevmgelig Endedel, der danner en mere eller 
mindre tydelig Vinkel med foregaaende Led, af kvis Lsengde 
den omtrent er. Af dens 2 Led er det lste noget kortere 
end det 2det og kolleformigt opsvulmet i Enden. Sidste 
Led er af aflang oval Form, stnmpt tilrundet i Enden og, 
ligesom det foregaaende. tset besat mod korte og stive 
Burster. 
De falske Fodder (se Fig. 1 a, 1 b), der som ssedvan- 
lig udspringer til liver Side fra et afrundet Fremspring lige 
foran og noget nedenfor Basis at de forreste Sidefortsatser, 
og erboiede ind under Legemet med on mere eller mindre 
stank S-formig Boining, er forholdsvis korte, idet de, lige 
udstrakte, neppe er lamgere end Legemet. De bestaar af 
10 tydeligt begraendsede Led, hvoraf de 3 forste er meget 
korte, bvorimod de 2 derpaa folgonde er temmelig forlaen- 
gede og indbyrdes omtrent lige lange. Endepartiet (Fig. 1 f) 
er kjendelig lamgere end disse 2 Led tilsammen og har 1 ste 
Led kun lidet stone end det fulgende, men adskilligt tyk- 
kere og tab haaret. De 4 vdre Led er stserkt sammen- 
trykte og aftager successivt i Storrelse samt bserer i Tnder- 
kanten en regelnnessig Rad af lancettormige Tomer, 7 — 8 
paa livert Led. Disse Tomer er (Fig. 1 g) alle af ens Ud- 
seende, grovt saugtakkede i Kanterne, og bestaar ligesom 
af 2 Afsnit, et tykkere basalt Parti, der til liver Side gaar 
ud i en stairk Torn, og et mere sammentrykt terminalt 
Parti, der i liver Kant liar 6 regelmsessige Saugtakker. 
Endekloen er tydeligt udviklet, noget kortere end sidste Led 
og fint tandet i Inderkanten. 
Gangfudderne (se Fig. 1) er forholdsvis kortere end 
bos de uvrige Arter af Slsegten, neppe mere end 3 Gauge 
l;engere end Legemet, og besatte med spredte, men stieike, 
nsesten tornformige Burster. Laarleddet er kun lidet lam- 
gere end Hoftepartiet og bos Huniien temmelig stserkt op- 
svulmet. lste Laegled er kortere end Laarleddet, hvoiimod 
2det Lsegled omtrent er af dette Leds Lsengde, men meget 
smalere. Det terminale Pai'ti af Foden (Tarsal- og Fod- 
leddet) er mere end halvt saa langt som 2det Lsegled og 
meget bevsegeligt forbunden med samme. Tarsalleddet er 
(se Fig. 1 h) forholdsvis kort, successivt udvidet mod Enden 
og ved det indre Hjurne bevsebnet med en staerk Torn. 
Fodleddet er mere end dob belt saa langt som Tarsalleddet

towards the base of the fingers, and densely beset with short 
hairs. The fingers are a trifle shorter than the palm, conically- 
acuminated, and have the points somewhat bent. I he inner 
edges of both fingers have a row of close-set small teeth and 
lie close together, when the chela is shut, the said teeth inter- 
locking with eacli other. The mobile finger is somewhat 
longer than the immobile one and less broad at the base. 
The palpi (fig. 1 e), issuing a little below the clieli- 
fori on either side of the base of the proboscis (se fig. 1 a), 
are somewhat shorter than the latter and much more slen- 
der. They are, as in all Nymphonids, composed of 5 joints, 
the 1st being very small. The 2 succeeding joints are 
prolonged and of about equal length, the outer one being 
somewhat tumified towards the end and beset on both edges t 
with a number of short bristles. The 2 last joints together 
constitute a rather mobile terminal part, which forms a 
more or less distinct angle with the preceding joint, the 
length of which it about equals. Of its 2 joints the 1st is 
a trifle shorter than the 2nd and claviformly tumified at tire 
extremity. The last joint is oblongo-oval in form, obtusely 
rounded at the end, and, like the preceding one, is densely 
beset with short, stiff bristles. 
The false logs (see fig. 1 a, 1 b), issuing as usual on 
either side from a rounded projection immediately anterior 
to and a little below the base of the foremost lateral pro- 
cesses, and bent in under the body with a more or less 
prominent S-sbaped curve, are comparatively short, at- 
taining, when fully extended, hardly the length ol the body. 
They have 10 distinctly defined joints, the 3 first being very 
short, whereas the 2 succeeding ones are considerably 
elongated and about equal in length. The terminal part 
(fig. If) is appreciably longer than those 2 joints taken 
together, and its 1st joint is but little larger than the 
following one, but a good deal thicker and densely hirsute. 
The 4 outer joints are very much compressed, diminish 
successively in size, and on the inner edge carry a re- 
gular series of lanceolate spines, 7— 8 on each joint. These 
spines (fig. 1 g) are all of tlyem similar in appearance, 
coarsely serrate along the edges, and consist, as it were, 
of 2 sections, a thicker basal part projecting on either 
side as a strong spine, and a more compressed terminal 
part with 6 regular secondary teeth on either edge. The 
terminal claw is distinctly developed, somewhat shorter than 
the last joint, and finely dentate on the inner margin. 
The ambulatory legs (see fig. 1) are relatively shorter 
than in the other species of the genus, being hardly more 
than 3 times longer than the body, and beset with scat- 
tered, but strong, well-nigh aculeiform bristles. The femoral 
joint is but little longer than the coxal part, and in the 
female considerably swollen. The 1st tibial joint is shorter 
than the femoral joint, whereas the 2nd tibial joint is about 
the same length as the latter, but is much more slender. 
The terminal part of the leg (tarsal and propodal joint) is 
more than half as long as the 2nd tibial joint and very flexibly 
connected to it. The tarsal joint (see fig. 1 h) is compa- 
ratively short, successively expanded towards the extremity, 
and armed at its inner corner with a strong spine. The
