Do fric Forkropssegmenter er kun veil smaa og smale 
laterale Inclsnit adskilte fra hinanden. Det forreste er be- 
tydelig kortere end de 0vrige, som omtrent er dobbelt saa 
brede som lange. 
Bagkroppen er af ssedvanligt Udseende og bar sidste 
Segment meget kort og bagtil stumpt tilrundet. 
Af 0ine eller sserskilte fra Hovedskjoldet afgrsendsede 
0ieiilober er der ligesaalidt som hos Slsegtens ovrige Arter 
noget Spor at bemaerke. 
Iste Par Folere (Fig. 31) er omtrent af Hovedskjol- 
dets Laengde og bestaar kun af 3 Led, der hurtigt aftager 
i Tykkelse mod Enden. Iste Led er temmelig bredt ved 
Basis, lacngere end de 2 ovrigo tilsammen og langs sin indre 
Kant forsynet med en Bad af Bprster. Sidste Led er 
meget smalt, 1 meant og barer ved Spidsen et Knippe af 
usaedvanlig lange Borster. 
2det Par Folere (Fig. 32) er omtrent af samme Langde 
som Iste Par, men meget tyndere, og udmserket ved den 
betydelige Lamgde af de 2 midterste Led. 
Kindbakkerne (Fig. 33) viser den for Slag ten cbarac- 
teristiske Bygning. De er i Modsaetning til bvad Tilfaeldet 
er hos foregaaende Slaegt kraftigt udviklede og belt igjennem 
stmrkt incrusterede, med forholdsvis stort, kileformigt Corpus. 
Den forreste tandbaerende (iren gaar i lige Flugt med Corpus, 
men bpior sig ved Enden vinkelformigt indad og viser en 
lignende Forskjel i Bevmbniugeu paa ho ire og venstre Ivind- 
bakke som hos lbregaaemle Sbegt. Tyggefortsatsen udgaar 
fra Corpus under en ret Vinkel og er af cylindrisk Form, 
dog noget udvidet mod Enden og her bevtebnet med et 
Antal af stasrke knudeformige Udvsexter. 
De ovrige Munddele viser intet ussedvanligt i sin Byg- 
ning. 
Saxfodderne (Fig. 34) er vistnok kraftigt byggede, men 
har som hos Slsegtens Ovrige Arter selve Haanden forholdsvis 
liden og smal samt kortere end dot foregaaende Led (carpus). 
Fingrene er simple, uden nogen bemserkelig Crenulation og 
noget kortere end Palmen. 
De 3 folgende Fodpar (Fig. 35) er af meget spinkel 
Form, med Basalleddet ganske smalt og Endekloen tynd, 
bprsteformig. De 3 bagerste Par (Fig. 36) er temmelig ulig 
disse, betydelig kortere og har Basalledet meget tykt og 
opsvulmet. 
Bagkroppens Buglemmer (Fig. 37) er vel udviklede, 
med t£et borstebesatte Endeplader. 
Halevedhsengene (Fig. 38) er forholdsvis smaa, men 
■ forsynede med 2 vel udviklede og tydeligt 2-leddede (Irene, 
hvoraf den indre er noget, skjpndt ikke meget laengere end 
den ydre. 
Farven er den ssedvanlige hvide, her dog paa Grand 
af lntegumenternes Tyndhed mindre ren. 
Laengden at de stprste erholdte Exemplarer er kun 
lidet over l 1 //™. 
The free segments of the, anterior division of the body 
are separated from one another only by small and narrow 
lateral incisions. The foremost is considerably shorter than 
the rest, which are about twice as broad as long. 
The posterior division of the body is of the usual 
appearance, and has the last segment exceedingly short and, 
posteriorly, obtusely rounded. 
Of eyes, or of ocular lobes separated from the cephalic 
shield, there was, as in the other species of the genus, no 
trace to be detected. 
The 1st pair of antennas (fig. b!) are about of the 
same length as the cephalic shield, and consist of only 3 
joints, rapidly diminishing in thickness toward the extremity. 
The 1st joint is rather broad at the base, longer than the 
2 others taken together, and furnished on its inner margin 
with a row of bristles. 
The 2nd pair of antennae (fig. 32) are about of the 
same length as the 1st pair, but much more slender, and 
characterized by the considerable length of the 2 median 
joints. 
The mandibles (fig. 33) exhibit the structure peculiar 
to the genus. Contrary to what is the case in the preced- 
ing genus, they are powerfully developed, and strongly in- 
crusted throughout, with a comparatively large, wedge-like 
corpus. The foremost dentiferous branch extends in the 
same plane as the corpus, bending however straight inward 
at the extremity, and exhibiting a difference in the armature 
on the right and left mandibles similar to that observed in 
the preceding genus. The molar projection springs at right 
angles from the corpus ; it is cylindrical in form, though 
somewhat dilated at the extremity, where it has a number 
of strong, tuberculiform protuberances. 
The remaining oral appendages exhibit nothing unusual 
in their structure. 
The ckelipeds (fig. 34) are, indeed, powerfully developed, 
but have, as in the other species of the genus, the hand 
itself rather small and narrow, as also shorter than the 
preceding joint (carpus). The fingers are simple, without 
any obvious crenellation, and somewhat shorter than the 
palm. 
The 3 succeeding pairs of logs (tig. 35) are exceed- 
ingly feeble in structure, with the basal joint quite narrow, 
and the terminal claw slender, setiform. The 3 posterior 
pairs (fig. 36) differ a good deal from these, being shorter 
and having the basal joint exceedingly thick and swollen. 
The pleopods (fig. 37) are well developed, with densely 
setiferous terminal plates. 
The caudal appendages (fig. 38) are comparatively 
small, but furnished with 2 well developed and distinctly 
two-jointed branches, of which the inner is somewhat, though 
not much, longer than the outer. 
Colour, as usual, white, but less pure in this animal, 
owing to the great tenuity of the integuments. 
Length of the largest specimens taken but very little 
more than D/ 2 mm .
