Endepartiet noget kortere, Fodleddet smalt og forlsenget, 
noget krummet og fint haaret i Inderkanten, Endekloen

Bemserkninger. Denne Art, den eneste hidtil be- 
kjendte af Slaegten, er kjendeligt beskrevet af Kioyer og 
afbildet i Gaimard’s store Yaerk. Senere er den at Dr. 
Hansen underkastet en fornyet Undersogelse, hvorved enkelte 
interessante Forhold ved dens Bygning er bleven oplyste. 
Beskrivelse. Laengden af de af mig undersogte Ex- 
emplarer, regnet fra Panderanden til Enden af Haleseg- 
mentet, overstiger ikke 27/™, og Spandvidden er omtrent 
1 0"”". Dr. Hansen opgiver Laengden af et ualmindelig 
stort Exemplar til 4.9™”', hvorved dog ogsaa Snabelen er 
medtaget i lige fortilstrakt Stilling. 
Legemets Form (se PI. XIV, Fig. 1) maa idethele 
siges at vaere temmelig undersaetsig, skjondt paa langt naer 
ikke i den Grad som hos Arterne af foregaaende Slaegt, 
og navnlig er Lemmerne betydelig spinklere. Selve Krop- 
pen (Fig. 1 a, 1 b) er forlioldsvis plumpt bygget og har 
alle Segmenter meget skarpt afsatte fra liinanden. Ved 
forste 0iekast. svnes den at vsere ganske nogen, men ved 
stserk Forstorrelse viser det sig, at den overalt er taet 
laadden af overordentlig smaa og fine Haar. der ogsaa 
fortsastter sig ud paa Snabelen. Sidefortsatserne er ualmin-

vals and finely setous on the margins. Cephalic seg- 
ment diminishing greatly anteriorly, the frontal part only 
little expanded and bluntly truncated at the extremity. 
Caudal segment horizontal, about as long as the 3 pos- 
terior segments of the body taken together, and a little 
behind the middle furnished with a transversal series 
of 4—6 strong bristles. Oculaf tubercle somewhat in 
front of the middle of the cephalic segment, particularly 
narrow, cylindric, slightly tumeficated at the extremity, 
the lenses of medium size, near the point. Scape of 
the proboscis about same length as the ocular tubercle, 
the terminal part more than twice as long as it, fusiform, 
broadest near the base. Chelifori longer than the cep- 
halic segment and the following one together, the last 
joint of the scape longest, and, like the preceding one, 
beset at the top with strong, coarsely ciliated bristles, 
hand particularly small, terminating in a pointed process 
and furnished anteriorly with a small 2-jointed appendix. 
Palpi, straightly extended, about '/ 2 longer than the cheli- 
fori, 3rd joint longer than the 2 succeeding ones together, 
the terminal part about the length of the 5th joint. 
False legs- in the male about same length as the body, 
the 4th joint longest, the joint of the terminal part 
diminishing successively in size. Ambulatoiv legs not 
quite twice as long as the trunk, tapering towards the 
extremity and beset with strong, coarsely ciliated bristles, 
femoral joint about same length as the coxal part and, 
in the male, furnished near the base with a conically 
pointed process, the 2 tibial joints, mutually, of equal 
length, terminal part somewhat shorter, propodal joint 
narrow and elongated, somewhat bent and finely setous 
on the inner margin, terminal claw relatively shoit. 
Length of the body (exclusive of the proboscis) 2.50™”. 
Extent 10”“. 
Remarks. This species, the only one of the genus 
hitherto known, has been recognisably described by Kroyer, 
and figured in Gaimard’s great .work. Subsequently it has 
been subjected to a renewed investigation by Dr. Hansen, 
which has elucidated a few interesting features in respect 
of its structure. 
Description. The length of the specimens examined 
by the author, measured from the margin of the frontal part 
to the extremity of the caudal segment, does not exceed 
and the extent is about 10’"“. Dr. Hansen states 
the length of an unusually large specimen as 4.9”“ in 
which, however, the proboscis, in a straight anteriorly ex- 
tended condition, is also included. 
The body (see PI. XIV, fig. 1) must be said to be, 
altogether, pretty stout, although not nearly to the same 
degree as in the species of the preceding genus, and the 
limbs are, in particular, slenderer. The trunk itself (fig. 
1 a, 1 b) is relatively plumply built, and has all the seg- 
ments very sharply demarcated from each other. At 
the first glance it appears to be quite bare, but upon 
powerful enlargement it appears everywhere finely shaggy, 
with extremely minute and delicate hairs, which are also 
continued out upon the proboscis. The lateral processes
