Spidsen. Folerne smale, kort haarede, 2det Led betydelig
længere, inen smalere end 3die; dette noget længere end
de 2 ydre Led tilsammen; sidste Led meget lidet, ovalt.
De falske Fodder hos Hannen omtrent ’/i længere end
Legemet. Endedelen saa lang som 5te Led, Randtornerne
forholdsvis smaa, smalt lancetformige og grovt saugtakkede
i Kanterne. Gangfadderne stærkt forlængede, næsten 5
Gange længere end Legemet, men temmelig robuste og
kun lidet afsmalnende mod Enden, 2det Lægled mere end
3 Gange længere end det terminale Afsnit, Tarsal- og
Fodled omtrent af ens Længde, begge ualmindelig kraftige,
det sidste med 6—8 stærke Torner i Inderkanten;
Ende-kloen omtrent halvt saa lang som Fodleddet, temmelig
stærk; Bikløerne vel udviklede, næsten halvt saa lange
som Kloen. Legemets Længde 12’""; Spandvidde 117""".
Bemærkninger. Den mest iøinefaldende Character
for nærværende Art er de eiendommelige Fremspring paa
Kroppens Rygside, hvortil intet Spor findes hos nogen
anden bekjendt Art af Slægten. Ogsaa i flere andre
Henseender skiller den sig kjendeligt fra de i det foregaaende
beskrevne Arter, hvorimod den i sine anatomiske Detailler
idethele slutter sig meget nær til folgende Art.
Beskrivelse. Legemets Længde naar op til 12’"™
med en Spandvidde af 117™™, og den hører saaledes til
de største Arter af Slægten.
Formen maa (se PI. X, Fig. 2) vistnok idethele
kaldes’ smækker, men dog paa langt nær ikke i den Grad
som hos enkelte af de i det foregaaende omtalte Arter,
og navnlig har Gangfodderne, omend af betydelig Længde,
et umiskjendelig robust Præg. Selve Kroppen viser, seet
ovenfra (Fig. 2 a). den sædvanlige cylindriske Form, og
har Sidefortsatseme temmelig store og tykke samt skilte
ved vel markerede Mellemrum. Sees Kroppen fra Siden
(Fig. 2 b), fremtræder imidlertid en for nærværende Art
meget udmærkende Character, idet ethvert af de 3 forreste
Segmenter bagtil sees at hæve sig til et temmelig høit,
skarpt tilspidset og noget bagudrettet Fremspring. Ryggen
faar herved et eiendommeligt, ligesom saugtakket Udseende;
deraf Artsbetegnelsen. Hovedsegmentet er omtrent saa
langt som de 3 følgende Segmenter tilsammen og har en
vel markeret, skjøndt ikke meget forlænget Hals;
Pandedelen er kun meget lidet udvidet og neppe synderlig bredere
end de midterste Kropssegmenter.
Øieknuden (Fig. 2 c) er noget ophøiet, af stump
konisk Fonn og lidt bagudrettet, med Lindserne af
middelmaadig Størrelse og beliggende omtrent ved Midten af
Øieknudens Hoide.
Snabelen (se Fig. b) er forholdsvis stor og tyk,
omtrent af Hovedsegmentets Længde, og af den sædvanlige
cylindriske Form, dog lidt afsmalnende i sit ydre Parti.
incurvate at the points. Palpi narrow, short-ciliate, 2nd
joint considerably longer, but narrower than the 3rd; the
latter somewhat longer than the 2 outer joints taken together;
last joint very small, oval. False legs in the male about
one-fourth longer than the body, terminal part as long
as the 5th joint, marginal spines comparatively small,
narrow-lanceolate, and coarsely serrated on the edges.
Ambulatory legs much elongated, almost 5 times longer
than the body but rather robust, and tapering but slightly
towards the end, 2nd tibial joint more than 3 times
longer than the terminal section, tarsal and propodal
joints about same length, both uncommonly powerful,
the latter with 6—8 strong spines on the inner edge;
terminal claw about half as long as the propodal joint,
rather powerful; auxiliary claws well developed, almost
half as long as the claw itself. Length of body 12"’™;
extent 117™".
Remarks. The most conspicuous character of the
present species is, the peculiar projections on the dorsal
surface of the body, of which not a trace is observed in any
of the other known species of the genus. Also in several
other respects it is perceptibly distinguished from all the
previously described species, whereas, in its anatomical
details it approximates, on the whole, very closely to the
following form.
Description. The length of the body reaches as
much as 12™", with an extent of 117’"’", and the animal
pertains, therefore, to the largest species of the genus.
The form (Pl. X, fig. 2) must certainly, on the whole,
be described as slender, though not nearly to the extent
characterising divers of the species described above; in
particular, the ambulatory legs, though of considerable length,
exhibit an unmistakeably robust appearance. The trunk
itself, when viewed from above (fig. 2 a), exhibits the usual
cylindrical form, and has the lateral processes rather large
and thick, as well as separated by well marked intervals.
On viewing the trunk from the side (fig. 2 b), however,
a character prominently distinctive of this species appears,
as each of the 3 foremost segments, behind, are seen to
rise into a rather high, sharply acuminated and somewhat
posteriorly directed projection. The back thus acquires a
peculiar, as it were, serrated appearance; hence the specific
designation. The cephalic segment is about as long as
the 3 following segments taken together, and has a well
marked, though not very elongated neck; the frontal part
is but very little expanded and hardly at all broader than
the medial segments of the trunk.
The oculiferous tubercle (fig. 2 c) is somewhat
elevated, of obtuse conical form, and directed a little
backwards, with the lenses of moderate size and placed about
mid-way up the tubercle.
The proboscis (fig. 2 b) is comparatively large and
thick, about as long as the cephalic segment and of the
usual cylindrical form, though tapering slightly in its outer
part.
