Haai'besietning, og kun ved Enclen af Sidefortsatserne be- 
mserkes nogle meget smaa og fine Haar. Hovedsegmentet 
er om treat saa langt som de 2 folgende Segmeuter tilsam- 
men og bar en tydelig, skjondt ikke meget lang, cylindrisk 
Hals; Pandedelen er mindre starlet udvidet end bos de 
pvrige Arter, men skarpere afmarkeret fra Halsen. Hale- 
segmentet er, som hos Ch. tenellum, simpelt cylindnskt, men 
altid skjsevt opadrettet. 
Oieknuden (Fig. 2 c, 2 d) er stserkt ophoiet, meget 
smal og lidt bagudrettet; Spidsen er afstumpet og forsynet 
med 2 divergerende tornformige Fremspring. Lmdserne 
er af meget ulige Storrelse, idet det forreste Par er mere 
end dobbelt saa stort som det bagerste, der ogsaa liggei 
betydelig hoiere (se Fig. 2 d). 
Snabelen (se Fig. 2 a, 2 b) er af betydelig Storrelse, 
fuldkommen saa lang som Hovedsegmentet, lige fortilstrakt 
og af regelmressig cylindrisk Form. 
Saxlemmerne (ibid.) er forholdsvis svagere byggede 
end hos de ovrige Ai’ter, med Skaftet smalt cylindiiskt 
og besat med temmelig lange, men spredte Haar. Haanden 
(Fig. 2 e) er kjendelig kortere end Skaftet og har, som 
hos de ovrige Arter, Palmen forholdsvis kort og af trian- 
gular Form, med Inderkanten i sit ydre Parti tmt besat 
med lange og standee Haar. Fingrene er nmsten dobbelt 
saa lange som Palmen og, navnlig den bevmgelige, over- 
ordentlig tyrnle, samt stserkt krummede i Enden. Taenderne 
i Inderkanten er at samme Beskaffenhed som bos de 2 
foregaaende Arter. 
Folerne (Fig. 2 f) udmserker sig, ligesom Saxlemmerne, 
ved sin usaedvanlig spinkle Form og er, navnlig mod Enden, 
tnet haarede. Af Beddenc er 2det lsengst. He 2 ydie 
Led er indbyrdes omtrent af ens Lsengde og tilsammen 
betydelig lsmgere end 3die, begge meget smale. 
De falske Fodder hos Hannen (se Fig. 2 b, 2 g) er 
stserkt forkengede og tynde, forovrigt i sin Bygning naer 
overensstemmende med samme hos Ch. tenellum. 5te Led 
er starlet krummet og ganske successivt fortykket mod 
Enden samt kun besat med meget korte og fine Burster. 
Randtornerne (Fig. 2 i) er meget smale, mesten linesere, 
med stump Spids og Kanterne regelmsessigt saugtakkede. 
Endekloen (Fig. 2 h) har 7 Sidetamder. 
Gangfoddorne (se Fig. 2) er omtrent 3 Gange lamgere 
end Legemet, smrdeles spinkle og besat i sin hele Lsengde 
med temmelig lange men forholdsvis spredte Haar. Hos 
Hunnen er Laarleddet ualmindelig stserkt opblsest i sit 
basale Parti paa Grand af de indsluttede forholdsvis store 
JEgceller, medens det ydre Parti har bibeholdt sin oprmde- 
lige smale Form. Hos Hannen er hele dette Led saerdeles 
smalt og har Inderkanten ganske svagt bugtet, men uden 
tydelige Tuberkler. 2det Ltegled er overordentlig tyndt 
. og viser en eiendommelig, nsesten Sformig Bpining; det er 
kun lidet lsengere end lste Ltegled, men omtrent dobbelt 
saa langt som det terminate Afsnit. 
usual hairy covering, and only at the extremity of the lateral 
processes are there observed a few minute and delicate 
hairs. The cephalic segment is about as long as the 2 
following segments taken together, and has a distinct, 
though not very long, cylindrical neck; the frontal part 
is less expanded than in the other species, but moie 
distinctly demarcated from the neck. The caudal segment 
is, like that of Ch. tenellum , plain cvlindric, but always 
directed obliquely upwards. 
The ocular tubercle (fig. 2 c, 2 d) is strongly pro- 
minent, very narrow, and slightly directed backwards; the 
point is blunted and furnished with 2 divergent aculeiform 
projections. The lenses are of very diffei’eut size; the 
anterior pair being twice the size of the posterior pair, 
which, also, are placed considerably higher (see fig. 2 d). 
The proboscis (see fig. 2 a, 2 b) is of considerable 
size, quite as long as the cephalic segment, directed 
straight forward, and of regular cylindric form. 
The chelifori (ibid.) are relatively more slender in 
structure than in the other species, with the scape narrow 
cylindrical and beset with rather long but scattered setae. 
The hand (fig. 2 e) is appreciably shorter than the scape, 
and has, as in the other species, the palm relatively short 
and triangular in form, with the inner edge in its outer 
portion closely beset with long, stiff setae. Plie fingeis 
are almost twice as long as the palm, and, especially the 
mobile one, are extremely slender and greatly curved at 
the extremity. The teeth on the inner margin are of the 
same kind as in the 2 preceding species. 
The palpi (fig. 2 f), like the chelifori, are distinguished 
by their unusual slender form, and are, especially at the 
extremity, densely setous. Of the joints, the 2nd is the v 
longest. The 2 outer joints are, mutually, about equal in 
length, and are together considerably longer than the 3rd 
one; both very narrow. 
The false legs in the male (see fig. 2 b, 2 g) are 
greatly elongated and slender in structure; otherwise they 
almost correspond with the same limbs in Ch. tenellum. The 
5th joint is greatly bent, quite gradually tumefied towards 
the extremity, and only beset with very short and fine 
bristles. The marginal spines (fig. 2 i) are very delicate, 
almost linear, with blunt point, and the edges regulailv 
serrated. The terminal claw (fig. 2 h) has 7 lateral 
teeth. 
The ambulatory legs (see fig. 2) are about 3 times 
as long as the body, particularly slender, and beset 
throughout their entire length with pretty long but, rela- 
tively, scattered setae. In the female, the femoral joint is 
unusually greatly expanded in its basal portion, by reason 
of the enclosed relatively large egg-cells, whilst the outer 
portion maintains its original slender form. In the male, 
the whole of this joint is particularly slender, and has 
the inner margin quite faintly curvate, but without dis- 
tinct tubercles. The 2nd tibial joint is extremely thin 
and exhibits a peculiar almost S-formed curvature; it is 
only a little longer than the 1st tibial joint, but nearly 
twice as long as the terminal section.
