Artacharacter. Legemet af undersætsig Form, fint
laaddent oventil, med Sidefortsatserne tæt sammentrængte
og kortere end Kroppens Brede. Hovedsegmentet omtrent
saa langt som de 3 følgende Segmenter tilsammen, Halsen
særdeles kort og tyk, Pandedelen temmelig bred,
Halesegmentet noget opadrettet. Øieknuden forholdsvis lav, stumpt
tilrundet. Snabelen kortere end Hovedsegmentet.
Sax-lemmerne smaa, tæt og kort haarede, Haanden betydelig
kortere end Skaftet, med Palmen jevnt bred og længere
end Fingrene, der med samme danner en udpræget Vinkel.
Folerne ualmindelig smaa, 2det Led størst, sidste Led
afrundet ovalt, neppe kortere end næstsidste. De falske
Fødder omtrent af Legemets Længde. Randtornerne smaa,
noget krummede og utydeligt saugtakkede. Gangfødderne
kort laadne overalt, ualmindelig robuste, noget
sammentrykte, neppe 3 Gange længere end Legemet, 2det Lægled
jevnt bredt, omtrent 2’/j Gange længere end det terminale
Afsnit, Tarsalleddet ligesaa bredt som langt, Fodleddet
omtrent 3 Gange saa langt, noget opsvulmet i sit basale
Parti, med en Rad af circa 8 stærke, udad i Længde
tiltagende Torner i Inderkanten; Endekloen halvt saa lang
som Fodlecraet, stærkt krummet; Bikløerne vel udviklede,
af Endekloens halve Længde. Legemets Længde 6""";
Spandvidde 33""".
Bemærkninger. At den her omhandlede Fonn er
identisk med den af Krøyer under ovenstaaende Navn
beskrevne og afbildede Art, antager jeg for givet, og dette
bekræftes ogsaa ved den nylig af Dr. Hansen meddelte,
temmelig udførlige Diagnose. Derimod holder jeg det for
meget tvivlsomt, hvorvidt Krøyer’s og Fabricius’s Art er
den samme, og maa fremdeles fastholde, at der er vel saa

Specific Characters. Body thickset in form, delicately
pubescent above, with the lateral processes closely crowded
together and shorter than the trunk is broad. Cephalic
segment about as long as the 3 following segments taken
together, neck exceedingly short and thick, frontal part
rather broad, caudal segment directed somewhat upwards.
Oculiferous tubercle comparatively low, obtusely rounded.
Proboscis shorter than the cephalic segment. Chelifori
small, densely and shortly hispid, hand considerably shorter
than the scape, with the palm uniformly broad, and longer
than the fingers, which make with the former a prominent
angle. Palpi remarkably small, 2nd joint largest, last
joint rounded oval, hardly shorter than the penultimate
one False legs about the length of the body, marginal
spines small, somewhat bent and indistinctly serrated.
Ambulatory legs everywhere shortly hispid, uncommonly
robust, somewhat compressed, scarcely 3 times longer than
the body, 2nd tibial joint uniformly broad, about two and
a half times longer than the terminal section, tarsal joint
as broad as long, propodal joint about 3 times as long,
somewhat swollen in its basal part, with a row of about
8 strong spines on the inner edge, increasing in length
outwards; terminal claw half as loug as the propodal
joint, strongly bent; auxiliary claws well developed, half
the length of the terminal claw. Length of body 6""";
extent 33""".
Bemarks. That the fonn treated of here, is identical
with the species described and figured by Kröyer under
the above name, I assume to be certain, and the rather
full diagnosis lately given by Dr. Hansen tends to establish
this. On the other hand, I regard it to be highly
doubtful whether Krøyer’s and Fabricius’s species is the
same form, and must still maintain, that there is quite as
