Slaegtscharacteristik. Legemet af robust Form, del- 
vis pigget, mod. Sidefortsatserne mere eller mindre tset sam- 
mentrsengte. Hovedsegmentet af middelmaadig Storrclse, 
stserkt udvidet i Enden, mod forboldsvis kort og tyk Hals. 
De 2 sidstc Kropssegmenter tydeligt afgrsenscde fra hin- 
anden. Halesegmentet foi’lamget, koniskt, delvis pigget. 0ie- 
knuden stumpt tilrundet, med vel udviklede Synselementcr. 
Snabelen skjaevt nedadrettet, konisk. Spidsen mamilleformigt 
udtrukket, Mundaabningen omgivet af en tmt lvrands af 
line Borster. Saxlemmeme kraftigt udviklede, Skaftet pig- 
get, Saxen (bos fuldt udviklede Individer) robust, skraat 
nedadrettet, udvidet mod Eiulen, Fingreue indadrettede, 
korte og tykke, med tuberkelformige Frcraspring i Inder- 
kanten og stump Spids. De f'alske Fodder 10-leddede, en- 
dende med en vel udviklet Klo, 5te Led bos Hannen med 
en kort Flig i Enden. Gangfwlderne mere eller mindre 
underage tsige, piggede; Laarleddet bos Hunnen etserkt op- 
svulmet; Tarsalledddet meget lidet; Fodleddet mere eller 
mindre krummet, med stserke Torner i Inderkanten ; Ende- 
kloen kraftigt udviklet, men uden Spor af Bikloer. De 
ydre ACggemasser med talrige forboldsvis smaa /Eg omgivne 
af en fmlles Membran. 
Bemserkninger. Jeg er fuldkommen enig med Dr, 
Hansen i, at denne af Wilson forst opstillede Slffigt bor op- 
retholdes. Foruden ved den fuldstsendige Mangel af Bi- 
kloer, adskiller denne Slmgt sig fra den typiskc ved Here 
andre vigtige Characterer, saasom Snabelens Form, Saxlem- 
mernes Bygning, de med en tydelig Klo endende lalske 
Fodder, den eiendommelige piggede Bevsebning af Gangfod- 
clerne; endelig, som af Dr. Hansen paavist, ogsaa ved Ud- 
viklingen. Man kjender bidtil kun med Sikkerhed 2 her- 
ben horende Arter, som begge er nordiske og i det fol- 
gende naermere vil blive omtalte.

Generic Characters. Body robust in form, partly 
spinous, with lateral processes more or less crowded together. 
Cephalic segment of medium size, very much expanded at 
the extremity, with comparatively short and thick neck. 
The 2 last segments of the trunk distinctly defined from 
each other. Caudal segment produced, conic, partly spinous. 
Oculiferous tubercle obtusely rounded, with well developed 
visual elements. Proboscis directed obliquely downwards, 
conic, point mamilliforra exserted, oral orifice surrounded 
by a dense wreath of delicate bristles. Chelifori powerfully 
developed, scape spinous, the chela (in full-grown specimens) 
robust, directed obliquely downwards, expanded towards 
the extremity, fingers directed inwards, short and thick, 
with nodular projections on the inner edge and point 
obtuse. False legs ten-jointed, terminating with a ■well 
developed claw, 5th joint in male with a short lobe at the 
extremity. Ambulatory legs more or less thickset and spinous; 
femoral joint in female exceedingly swollen; tarsal joint very 
small; propodal joint more or less curved, with strong spines 
on the inner edge; terminal claw powerfully developed, but 
without any trace of auxiliary claws. The outer egg- 
masses, consisting of numerous comparatively small ova, 
enveloped in a common membrane. 
Remarks. I quite agree with Dr. Hansen, that this 
genus, first ctablished by Wilson, should be maintained. 
Besides its absolute want of auxiliary claws, the genus dif- 
fers from the typical one in divers other important charac- 
ters, as, for example, the form of the proboscis, the struc- 
ture of the chelifori, the false legs terminating in a distinct 
claw, the peculiar spinous armature of the ambulatory legs ; 
and finally, too, as pointed out by Dr. Hansen, in the de- 
velopment. Up to the present time, only 2 species can, with 
certainty, be referred to this genus; both Northern ones 
and which will subsequently be spoken of more at large.
