Bemserkninger. Denne ticlligere alenc af Wilson 
observerede Art slntter sig aabenbart nser til de 3 fore- 
gaaende Arter og danner saramen med dem en egen Q-ruppe 
af SI. Nymphon, vsesentlig karakteriseret ved de stserkt 
forltengede Saxlemraer og Folere. Naermest synes den at 
komme N. elegans Hansen, men er dog let kjendelig ved 
den ualmindelig spinkle Form af samtlige Lemmer. Sax- 
lemmernes Haand er saaledes endnu betydelig smalere og 
navnHg ulig ved den Maade, hvorpaa Fingrene ender. Ogsaa 
Folerne skiller sig kjendeligt ved et forskjelligt Lrengde- 
forhold af do dem sammenssettende Led. Bndelig er Bi- 
kloorues ualmindelige Stoi-relse et godt og sikkert Kjende- 
nuerke. 
Beskrivelse. Legemets Laeijgde er hos de stdrste 
undersogte Exemplarer 8 mm , med en Spandvidde af 85“ m . 
Arten opnaar saaledes ikke fuldt samme Stdrrelse som 
N. elegans. 
Formen er idethele (se PL IX, Fig. 2) ualmindelig 
spinkel, isser hvad Lemmerne angaar. Selve Kroppen 
(Fig. 2 a) er af den ssedvanlige smalt cylindriske Form 
og bar Sidefortsatserne temmelig vidt skilte. Hovedseg- 
mentet er ogsaa hos denne Art af betydelig StOrrelse, idet 
dets Lmngde er lig de 3 folgende Segmenter tilsammen, 
og Pandedelen er temmelig stserkt udvidet, omend ikke 
fuldt saa stserkt som hos de 3 foregaaende Artor. Halsen 
er kjendelig tyndere og ogsaa noget mere forhenget end 
hos hine Arter. 
0ieknuden (Fig. 2 b) er temmelig stserkt ophoiet, af 
noget pyramidal Form og afstumpet i Enden. Lindserne 
er af betydelig Storrelse og elliptisk Form. 
Snabelen (se Fig. 2 a) er af regelmsessig cylindrisk 
Form og omtrent af Hovedsegmentets Lsengde. 
Saxlemmerne (ibid.) udmaerker sig ved sin spinkle 
Form og er, lige udstrakte omtrent af Kroppens Lsengde 
(-5- Snabelen). Skaftct er smalt cylindriskt og ganske lige, 
ikke som hos foregaaende Art bpiet i Enden, samt bserer 
1 den ovre Kant user Spidsen nogle temmelig lange og 
tynde Burster. Haandei), der omtrent er af Skaftets 
Lsengde, er sserdeles smal og har Fingrene kjendelig hen- 
gere end Palmen. Begge Fingre er overordentlig tynde 
og ender med en yderst fin, jevnt indboiet Spids (se Fig. 
2 d); i Inderkanten bserer de talrige spidse Tsender, der 
navnlig paa den ubevsegelige Finger er af betydelig Lsengde, 
skjpndt noget ulige i Stprrelse. 
Folerne (Fig. 2 e) er endnu tyndere end hos fore- 
gaaende Art og viser et noget forskjelligt Lsengdeforhold 
af Leddene. 2det Led er saaledes her nsesten dobbelt saa 
langt som 3die, og af de 2 ydre Led er det sidste baade 
kortere og betydelig smalere end mcstsidste; begge disse 
Led tilsammen er kjendelig lsengere end 3die. 
De falske Fodder udspringer som hos foregaaende 
Art fra Siderne af Halsen og i nogen Afstand fra de for- 
reste Sidefortsatser (se Fig. 2). De er hos Hannen 
B,emarks. This animal, previously observed by Wilson 
alone, has, it is evident, great affinity to the 3 foregoing 
species, and constitutes along with them a separate group 
of the genus Nymphon, characterized, in particular, by the 
exceedingly elongated chelifori and palpi. It seems to 
approximate closest N. elegans Hansen, but yet is, easily 
distinguished by the remarkably slender form of all its 
limbs. The hand of the chelifori is, thus, very much nar- 
rower, and especially dissimilar in the way in which the 
fingers terminate. The palpi, too, differ appreciably in 
the longitudinal proportions of the joints composing them. 
Finally, the unusual size of the auxiliary claws is a good 
and reliable distinctive character. 
Description. The length of the body in the largest 
specimens examined is 8””", with an extent of 8o mm . 
The species, therefore, does not quite attain the size of 
N. elegans. 
The form is, on the whole, (see PI. IX, fig. 2) uncom- 
monly slender, particularly as regards the limbs. The 
trunk itself (fig. 2 a) is of the usual narrow-cylindrical 
form, and has the lateral processes rather widely sep- 
arated. The cephalic segment occurs in this species, too, 
of considerable size, its length equalling that of the 3 fol- 
lowing segments taken together, and the frontal part is a 
good deal expanded, though not quite so much as in the 
3 preceding species. The neck is appreciably thinner, and 
also somewhat more elongated than in those forms. 
Tlie oculiforous tubercle (fig. 2 b) is rather consider- 
ably elevated, of a somewhat pyramidal form, and blunted at 
the extremity. The lenses are large and elliptic in form 
The proboscis (see fig. 2 a) has a regular cylindrical 
form, and is about same length as the cephalic segment. 
The chelifori (ibid.) distinguish themselves by their 
slender form, and, when fully extended, are about same length 
as the body (less the proboscis). The scape is narrow-cylin- 
drical and quite straight, not as in the preceding species 
bent at the extremity, also furnished on the upper edge near 
the point with a few rather long and slender set®. The 
hand, of about the length of the scape, is exceedingly 
narrow, and has the fingers appreciably longer than the 
palm. Both fingers are remarkably thin, and terminate 
in a very fine, evenly incurvated point (see fig. 2 d); on 
the inner edge they carry numerous sharp teeth, which, 
more particularly on the immobile finger, are of consider- 
able length though somewhat unequal in size. 
The palpi (fig. 2 e) are even thinner than in the 
preceding species, and shew a somewhat different longitud- 
inal relation in the joints. The 2nd joint is, thus, in this 
animal, almost twice as long as the 3rd one, and of the 
2 outer joints, the last is both shorter and considerably 
narrower than the penultimate one ; both these joints taken 
together are appreciably longer than the 3rd. 
The false legs issue, as in the foregoing species, 
from the sides of the neck, and at some distance from the 
foremost of the lateral processes (see fig. 2). In the
