med et stærkt chitiniseret knudeformigt Fremspring.
Sidehjørnerne af Hovedsegmentet mindre uddragne end hos A.
echinata. Øieknuden lige opadrettet. pyramidal, endende
i en konisk Spids, Lindserne omtrent ved Midten. Snabelen
stærkt nedadrettet, neppe mere end halvt saa lang som
Legemet. Saxlemmerne noget niere end halvt saa lange
som Snabelen, Skaftet kølleformigt, uden nogen tydelig
dorsal Fortsats, Endedelen uregelmæssig oval. Følerne
8-leddede, ’2det Led kortere end 4de, Endedelen omtrent
af dette sidstes Længde. Gangfødderne neppe dobbelt saa
lange som Legemet, uden tydelige Pigge, men med spredte
Haar, 1ste Hofteled oventil ved Enden forsynet med en
knudeformig Fortsats, alle Hofteled hos Hannen temmelig
tæt haarede; Fodleddet forholdsvis endnu kraftigere end
hos foregaaende Art, noget fortykket paa Midten;
Endekloen over halvt saa lang som Fodleddet, Bikløerne
særdeles smaa. Legemets Længde 1.50"""; Spandvidde 6™’.
Bemærkninger. Jeg antager det for rimeligt, at
dette er Hodge’s Achelia lævis, men Beskrivelsen er altfor
ufuldstændig til med fuld Sikkerhed at afgjøre om saa er
Tilfældet. Arten er imidlertid i begge Kjøn meget let at
kjende fra foregaaende, navnlig ved den fuldstændige
Sam-menvoxning af alle Kropssegmenter, ved Øieknudens Fonn
og Gangføddernes Mangel af Pigge. Ogsaa i
Saxlemmer-nes og Følernes Bygning er der, som af ovenstaaende
Diagnose vil sees, vel udprægede Differentser. Foruden
Han og Hun har jeg af denne Art ogsaa havt Anledning
til at undersøge ganske unge Individer med tydeligt
cheli-forme Saxlemmer.
Beskrivelse. Legemets La’iigde er hos dell fuldt
udvidlede Hun neppe mere l’/a™, med en Spandvidde af
6""". Hannen er ubetydelig større.
I ydre Habitus har denne Art (se PI. XIII, Fig. 2,
2 a) stor Lighed med foregaaende. Kroppen (Fig. 2 b,
2 c) er dog om muligt endnu noget plumpere og i høi
Grad udmærket derved, at samtlige Segmenter er
fuldstændig sammenvoxne, uden at det mindste Tegn til nogen
Tværsuturer kan opdages hverken oventil eller nedentil.
Sidefortsatserne er forholdsvis noget kortere end hos
foregaaende Art og har ved Enden oventil, som hos denne, 2
Fortsatser; men disse er her meget ulige, idet dell forreste
er meget liden, tilspidset og paa Toppen forsynet med en
kort Børste, medens den bagerste har Formen af en
temmelig stor og stærkt chitiniseret konisk Knude uden
terminal Børste. Hovedsegmentet er, som hos foregaaende
Art, fortil næsten lige afkuttet, men har Sidehjørnerne
betydelig mindre fremspringende. Halesegmentet er af
lignende Udseende som hos J. echinata.
Øieknuden (Fig. 2 d) er lige opadrettet, stærkt
ophøiet og af pyramidal Form, fra Midten af successivt
setiferous process, and posteriorly with a strongly ehitiiiised
nodiform protuberance. Lateral corners of the cephalic
segment less drawn out than in A. echinata. Ocular
tubercle directed straightly upwards, pyramidal,
terminating in a conical point; the lenses situated nearly in
the middle. Proboscis directed strongly downwards,
scarcely more than half the length of the body.
Chelifori somewhat more than half as long as the proboscis,
scape claviform, without any distinct dorsal process,
terminal part irregularly oval. Palpi 8-jointed. 2nd
joint shorter than the 4th, terminal part about same
length as the last-named. Ambulatory legs scarcely
twice as long as the body, without distinct spines but
with scattered setæ, 1st coxal joint furnished’at the end
above with a nodiform process, all the coxal joints
in the male rather densely setous; propodal joint,
relatively still more powerful than in the preceding species,
somewhat tumeficated at the middle; the terminal claw
more than half as long as the propodal joint,
auxiliary claws particularly small. Length of the body 1.50""";
extent 0""".
Remarks. I suppose it to be probable that this is
Hodge’s Achelia lævis. but the description is much too
incomplete to enable this to be determined with perfect
certainty. The species is, however, in both sexes, verv
easy to distinguish from the preceding one, particularly
by the perfect accretion of all the segments of the body,
by the form of the ocular tubercle, aiid the absence of
spines on .the ambulatory legs. In the structure of the
chelifori and palpi also, as will be observed from the
above diagnosis, there are marked differences. Besides
male and female, 1 have, also, of this species, had the
opportunity of investigating quite young individuals with
distinct forcipated chelifori.
Description. The length of the body in the fully
developed female is scarcely more than 11/._.""" with an
extent ot 6""". The male is inconsiderably larger.
In external habit this species has (see Pl. XIII,
fig. 2, 2 a) great resemblance to the preceding one. The
trunk (fig. 2 b, 2 c) is, however, if possible, still more
thick-set, and in an eminent degree remarkable by the
fact that all the segments are completely coalesced, without
it being possible to observe the least trace of any
transversal sutures either above or below. The lateral
processes are relatively somewhat shorter than in the
preceding species, and, like it, have, at the extremity above,
2 processes, but these are here very unlike, inasmuch
that the foremost one is very small, pointed, and at the
top furnished with a short bristle, while the posterior one
has the shape of a pretty large and strongly chitinised
conical nodule without a terminal bristle. The cephalic
segment is, as in the preceding species, almost straightly
truncated in front, but has the lateral corners considerably
less prominent. The caudal segment resembles in
appearance that of A. echinata.
The ocular tubercle (fig. 2 d) is directed straight
upwards, strongly protuberant, and pyramidal in form,
