gende tilsammen. Bisvoben ex' forholdsvis liden og bestaar 
kun af 3 Led. 
2det Par Folere (Pig. 3 b) er omtrent af samme Lsengde 
som IstePar og har Skaftets naxstsidste Led kengst. Svoben 
er xieppe lfengere end paa lste Par og bestaar omtrent af 
det samme Antal Led. 
Miuiddelene dtekkes ikke ganske til Siderne af lste 
Pax- Epimerer, men rager for en Del frit frem nedenfor 
samme (se Pig. 3). I deres Bygning er der kun liden 
Porskjel at bemserke fra de 2 lrengere nedenfor beskrevne 
Aider. 
Kindbakkerne ( Pig. 3 c) har Tyggeknuden vel udviklet 
og temmelig stferkt fremspi’ingeiide. Palpen er fsestet i 
Hoide med denne og er temmelig stor, med sidste Led 
noget udvidet paa Midten og taet borstebesat. 
lste Pax- Kjxever (Pig. 3 d) liar den midterste Gren 
(den egentlige Tyggelap) kraftigt udviklet og bevsebnet med 
stserke Torner. Den indre Lap er derimod ganske liden 
og ved Spidsxm forsynet med 2 cilierede Borster. Palpen 
overrager kun lidet den midterste Lap og er paa Enden 
af det samxnentrykte sidste Led forsynet med en Rad af 
korte Torner. 
2det Pai' Kjaxver (Fig. 3 e) bestaar som ssedvanligt 
af 2 fra en belles Basaldel udgaaende Lapper, hvoraf den 
indre er noget mindre end den ydre, begge t;et borstebe- 
satte, 
Kjievefodderixe (Fig. 3 /) viser den ssedvanlige Byg- 
ning. Den ydre Tyggelap er temmelig stor, af skjsevt oval 
Form og ved det indre Hjorne forsynet med en Del Torner. 
Palpens sidste Led er meget smalt, linexert og kun sparsonxt 
bprstebesat, Endekloen forholdsvis svag. 
lste Podpar (Pig. 3 g) er temmelig undersxetsigt bygget 
og xxfuldkomment subcheliformt ligesom hos Arterne af 
Skegterne Lysianassa og Socarnes. Sidste Led tiller Haan- 
den er omtrent saa langt som de 2 foregaaende Led til- 
sammen og afsmalner jevns mod Enden uden at vise nogen 
tydeligt begrsendset Griberand. 
2det Podpar (Pig. 3 h) viser den tor Pamilien char- 
acteristiske spixilde Bygning og har de 3 ydre Led tmt 
haarede og Endekloen rudimentser. 
De 2 folgende Podpar (Pig. 3 i) udmserker sig isser 
ved den usxedvanlige Form af Endekloen. Denne er tem- 
melig tyk, dolkformig og neppe mxerkeligt knxmmet. 
De 3 bagre Podpar (se Pig. 3) har som ssedvanligt 
Hofteleddet pladeformigt udvidet, af oval Form og i den 
bagre Rand utydeligt saugtakket. Sidste Par (Fig. 3 k) 
udmsei-ker sig dog i hoi Grad derved, at det nedre bagre 
Hjorne af dette Led er udtruklcet i en skarp dolkformig 
og skraat bagudrettet Poi'tsats, ligesom en Spore. 
the 1st being, as usual, lai'gest, and about equal in length 
to the 2 succeeding ones, taken together. The secondary 
bagel lu m is comparatively small, and consists of only 3 
articulations. 
The 2nd pair of antennae (fig. 36) are about of the 
same length as the 1st pair, and -have the penultimate joint 
of the peduncle longest. The flagellum is scarcely at all 
longer than that on the 1st pair, and consists about of the 
same number of articulations. 
The oral appendages are not quite covered at the 
sides by the 1st pair of epimera, projecting as they do, in 
part, freely forward below them (see fig. 3). In structure, 
they exhibit but little difference from those in the 2 species 
described below. 
The mandibles (fig. 3 c) have the molar protuberance 
well developed and rather prominently projecting. The palp, 
attached at the same height as the protuberance, is com- 
paratively large, with the last joint somewhat dilated in the 
middle and densely beset with bristles. 
The 1st pair of maxillm (fig. 3 d) have the medial 
branch (the true masticatory lobe) powerfully developed, 
and armed with strong spines. The inner lobe, on the 
xithcr hand, is quite small, and furnished at the point with 
2 ciliated bristles. The palp projects but little beyond the 
medial lobe, and is furnished at the extremity of the com- 
pressed terminal joint with a row of short spines. 
The 2nd pair of maxillae (fig. 3 e) consist as usual 
of 2 lobes proceeding from a common basal part, of which 
the inner is somewhat smaller than the outer — both densely 
beset with bristles. 
The uxaxiUipeds (fig. 3 f) exhibit the usual structure. 
The outer masticatory lobe is rather large, obliquely oval 
in form, and at the inner corner armed with a number of 
spines. The hist articulation of the palp is exceedingly 
slender, linear, and but sparingly beset with bristles — the 
terminal claw comparatively weak. 
The 1st pair ot legs (fig. 3 g) are rather thickset in 
structure, and imperfectly subcheliform, as in the species 
of the genera Lysianassa and Socarnes. The terminal ar- 
ticulation, or hand, is about as long as the 2 preceding 
articulations taken together, and tapers gradually towards 
the end. without exhibiting any distinctly defined palm. 
The 2nd pair of legs (fig. 3 h) exhibit the slim, fragile 
structure characteristic of the family; they have the outer 3 
articulations thickly covered with hair and the terminal 
claw rudimentary. 
The 2 succeeding pairs of legs (fig. 3 i) are disting- 
uished more especially by the unusual form of the terminal 
claw, which is rather thick, dagger-shaped, and well-nigh 
imperceptibly curved. 
The 3 posterior pairs of legs (see fig. 3) have, as 
usual, the basal joint lamelliform-dilated, oval in structure, 
and, along the posterior margin, indistinctly serrate. The 
last pair (fig. 3 k) are highly characterized by the lower 
posterior corner of the said joint being drawn out as a 
sharp, dagger-shaped projection, or, as it were, spur, di- 
rected obliquely backward.
