Slsegtseharacter. Legemet mere eller mindre smsek- 
kert. med forholdsvis lange Sidefortsatser. Hovedsegmentet 
fortil indknebet og fremragende over Roden af Snabelen. 
Halesegmentet mere eller mindre forlsenget. 0ieknuden 
beliggende yed Enden af Pandedelen, vel udviklet eller 
rudimentser. Snabelen udgaaende fra Hovedsegmentets ven- 
trale Side, skraat nedadrettet. Saxlemmerne forholdsvis 
svage, liaarbesatte, med Saxen liden og .Fingrene neppo 
forciperede. De falske Fodder hos Hannen 6-leddede, 
sidste Led meget lidet, borstebesat, uden Klo. Gangfpd- 
derne spinkle, mere eller mindre forlamgede, sparsomt 
liaarbesatte. Tarsalleddet meget kort, Fodleddct forlsenget, 
med Inderkanten fremspringende ved Basis og her bevseb- 
net med stserke Torner, Endekloen stserkt forlsengst. lofor-

gende foran Endekloens Yderkant. Flere kuglelormige

Bemserkninger. Den Character, hvorpaa W ilson 
vsesentlig synes at have gruudet denne Sliegt, nemlig den 
formentlige Mangel af Bikloer, er vistnok ubrugelig, da 
saadanne i Yirkeligheden forefindes, skjondt i en meget 
rudimentser Tilstand; men jeg tror dog, at Slsegten bor 
opretholdes, da de herlien horende Arter viser en Del 
andre eiendommelige Characterer, der synes at maatte 
kunne tillmgges generisk Betvdning, saasom Hovedsegmen- 
tets characteristiske Form, Saxlemmernes svagere Bygning, 
og navniig det storre Antal Led i do falske Fodder. 
Slsegten synes at tadle ikke faa Arter. Foruden den typi- 
ske Form, A. lentus Wilson, og do to nedenfor nmrmere 
beskrevne Arter, horer herlien Phoxichilidium virescens 
Hodge, samt efter al Sandsynlighcd de 2 af Dolirn be- 
skrevne middelhavske Arter, P. angidatum og exiguum. 
Endelig synes den af Hoek fra Challenger Expeditionen 
opforte Art P. insigne, ialfald at domme efter de falske 
Fodders Hdseende, nsermest at maatte henregnes til samme 
Slsegt.

Generic Character. Body more or less slender, with 
comparatively long lateral processes. Cephalic segment 
anteriorly constricted and projecting beyond base of pro- 
boscis. Caudal segment more or less elongate. Oculifer- 
ous tubercle located at extremity of lrontal part, well-deve- 
loped or rudimentary. Proboscis issuing from ventral side 
of cephalic segment, directed obliquely downwards. Cheli- 
fori comparatively feeble, covered with hair, having the 
chela small and the fingers scarcely forcipate. False legs 
in the male 6-jointed, terminal joint very small, bristle- 
bearing, without any claw. Ambulatory legs slender, more 
or less elongate, sparingly hair-beset, tarsal joint very short, 
propodal joint produced, with inner margin projecting at 
base, and armed there with strong spines, terminal claw 
elongate, falciform, auxiliary claws exceedingly small and 
rudimentary, not projecting beyond outer margin of ter- 
minal claw. Several globular egg-masses attached to the 
false legs in the male. 
Remarks. — The character on which Wilson would 
seem to have chiefly founded this species, viz., its supposed 
want of auxiliary claws, is certainly untenable, as such do 
really occur, although in a very rudimentary state; meanwhile 
the genus should, I cannot hut think, he retained, as the 
species classed under it exhibit certain other peculiar 
characters, to which apparently we can assign generic 
value, thus, for example, the characteristic form of the 
cephalic segment, the feebler structure of the chelifori, and 
more especially the greater numbef of joints in the false 
leg S . The genus would appear to comprise not a few 
species. Excluding the typical form, A. lentus, Wilson, 
and the 2 species described below, it counts Phoxichilidium 
virescens , Hodge, and in all probability the 2 Mediterranean 
species, P. angulatum and exiguum, described by Dohrn. 
Finally, the species etablished by Hoek from the Chal- 
lenger” Expedition, P. insigne, judging at least by the ap- 
pearance of the false legs, would appear to approximate 
the same genus closest.
