derne neppe 3 G-ange lamgere end Legemet, temmelig 
spinkle og tset haarede, Laarleddet hos Hannen med kun 
3 Knnder i Inderkanten, det* terminale Parti meget smalt, 
Tarsalleddet lineaert, Fodleddet ikke fuldt dobbelt saa langt, 
med talrige lange og tynde Torner i Inderkanten; Ende- 
kloen omtrent halvt saa lang som Fodleddet; Bikloerne

Bemserkninger. Fra de 3 foregaaende Arter skiller 
denne sig ved en kjendelig spinklere Kropsform, hvad der 
Far givet Anledning til Artsbetegnelsen. Mest synes den 
at nserme sig til Ch. spinosum, men den smalt cylindriske 
Krop, 0ieknudens Form og Here andre Characterer skiller 
den bestemt fra samme. 
Beskrivelse. Legemets Lsengde hos den fuldt ud- 
viklede Han er kun 6 1 / 3 mra , med en Spandvidde af 34 wra , 
og denne Art er saaledes betydelig mindre end de i det 
foregaaende omtalte Former. 
Legemet er (se PL XII, Fig. 1) betydelig spinklere 
end hos nogen af de ovenfor omtalte Arter, og navnlig er 
selve Kroppen (se Fig. 1 a, 1 b) kjendelig smalere, ntesten 
cylindrisk, med Sidefortsatserne skilte ved temmelig brede 
Mellemrum. Paa Rygsiden er Segmenterne besatte med 
meget smaa, men tsette Haar, og det samme er ogsaa 
Tilfaddet med de temmelig tykke og plumpe Sidefortsatser. 
Hovedsegmentet er neppe laengere end de 2 felgende Seg- 
menter tilsammen og har en tydelig, men kort Hals ; Pande- 
delen udvides ganske successivt mod Enden og er her nsesten 
dobbelt saa bred som Kroppen paa Midten. Halescgmentet 
er af simpel cylindrisk Form, stumpt afrundet i Enden, og 
horizontalt. 
0ieknuden (Fig. 1 c) er noget mindre ophoiet end 
hos Ch. hirtipes og Ch. spinosum, men mere fremragende 
end hos Ch. hirtum. Den er lige opadrettet og af stump 
konisk Form, uden tydelige knudeformige Fremspring. 
Lindserne er forholdsvis store, elliptiske og beliggende 
nsermere Enden end Basis af 0ieknuden. 
Snabelen (se Fig. 1 a) er kortere end Hovedseg- 
mentet, horizontalt fortilrettet, og kjendelig afsmalnende 
mod Enden. 
Saxlemmerne (ibid.) ligner noget samme hos Ch. 
spinosum, men er noget spinklere og har Haanden (Fig. 
1 d) forholdsvis kortere og mindre strnrkt vroden. Palmen 
er forholdsvis storre og af temmelig regelmsessig trekantet 
Form, hvorimod Fingrene er betydelig kortere og mindre 
staii'kt krummede. Tmnderne i Inderkanten af Fingrene 
er lange og tynde, men ficrre i Antal end hos Ch. spinosum. 
Folerne (Fig. 1 e) er temmelig stmrkt forlsengede 
og, navnlig i sit ydre Parti, tfet haarede. Forholdet af 
Leddene skiller sig kjendeligt fra samme hos de foregaaende 
successively expanded towards the extremity, and short- 
hairy there; marginal spines comparatively small, obtusely 
lanceolate, irregularly crenulated on the edges. Ambul- 
atory legs scarcely 3 times longer than the body, rather 
slender and densely setous, femoral joint in male with only 
3 nodules on the inner edge, terminal part very narrow, 
tarsal joint linear, propodal joint not quite twice its 
length, with numerous long and slender spines on the 
inner edge; terminal claw about half as long as the propo- 
dal joint; auxiliary claws well developed. Length of body 
6 1 / 3 m ”'; extent 34"™. 
Remarks. From the 3 foregoing species the present 
differs in its appreciably slimmer body, which feature 
has suggested the specific designation. It seems to ap- 
proximate Ch. spinosum closest, but the narrow cylindri- 
cal trunk, the form of the oculiferous tubercle and 
several other characters distinguish it clearly from that 
species. 
Description. The length of the body in the fully 
developed male is only 6 1 //™, with an extent of 34'"™, 
and this species is accordingly much smaller than the 
preceding forms. 
The body (see PI. XII, fig. 1) is a good deal slim- 
mer than in any of the species above recorded, and more 
especially the trunk (see fig. la, lb) is appreciably 
narrower, well-nigh cylindric, with the lateral processes 
separated by rather wide intervals. On the dorsal side 
the segments are beset with very short but dense hairs, 
and that is also the case -with the rather thick and 
clumsy lateral processes. The cephalic segment is hardly 
longer than the 2 following segments taken together, and 
has a distinct though short neck; the frontal part expands 
successively towards the end, and is there almost twice 
as broad as the trunk in the middle. The caudal seg- 
ment is of simple cylindric form, obtusely rounded at the 
extremity, and horizontal. 
The oculiferous tubercle (fig. 1 c) is somewhat less 
elevated than in Ch. hirtipes and Ch. spinosum, but more 
prominent than in Ch. hirtum. It points straight upwards, 
and is conico-obtuse in form, without any distinct tubercu- 
liform projections. The lenses are comparatively large, 
elliptic, and placed nearer the extremity than the base of 
the tubercle. 
The proboscis (see fig. 1 a) is shorter than the 
cephalic segment, directed horizontally forwards, and tapers 
appreciably towards the extremity. 
The chelifori (ibid.) somewhat resemble those of Ch. 
spinosum , but are a little slenderer, and have the hand 
(fig. 1 d) relatively shorter and less contorted. The palm 
is relatively larger and tolerably regularly triangular in 
form, whereas the fingers are considerably shorter and less 
sharply curved. The teeth on the inner edge of the fin- 
gers are long and thin, but fewer in number than in Ch. 
spinosum. 
The palpi (fig. 1 e) are rather greatly elongated, and, 
particularly in their outer part, densely setous. The pro- 
portion between the joints differs appreciably from that in the
