Bemærkninger. Denne Slægt staal" vistnok meget
nær foregaaende, men synes mig dog at burde opretholdes,
da flere Arter i den nyere Tid er opdagede, der viser
lignende Forskjelligheder fra Slægten Eurycyde som den
typiske Art. Af disse Forskjelligheder kan fremhæves den
sinale forlængede Form af Legemet. Snabelens enorme
Udvikling og Mangel af noget tydeligt Skaft.
Saxlemmernes Structur, endelig de falske Fodders Bevæbning og
Halesegmentets Form. Den af Dohrn opstillede Slægt
Barana synes i visse Henseender at komme nærværende
Type endnu nærmere end foregaaende Slægt, og navnlig
viser den ene af Arterne, B. castelli, i sin ydre Hahitus en
umiskjendelig Lighed med Arterne af Slægten
Ascorhyn-chus, medens den anden Art, B. arenosa i denne
Henseende mere minder om Slægten Eurycyde. Der er
imidlertid visse Furhold, der synes at skille begge disse Arter
saavel fra Slægten Eurycyde som Ascorhynchus og soul
taler imod at forene dem med nogen af disse Slægter.
Foruden den nedenfor nærmere beskrevne Art hører herhen
3 af Hoek fra Challenger Expeditionen beskrevne Arter,
og en af Bohm under Benævnelsen Gnamptorliynchus ramipes
opfort Fonn fra Japan henføres af Hoek ligeledes til denne
Slægt. Arternes Antal bliver saaledes for Tiden ikke
mindre end 5 ialt.

Remarks. This genus certainly approximates to the
preceding one pretty closely, but it appears to me,
bow-ever, that it should be maintained, as several species have
been discovered in later years which exhibit similar
divergencies from the genus Eurycyde as the typical species.
Of these divergencies may be accentuated, the narrow
elongated form of the body, the enormous development of the
proboscis and the absence of any distinct scape, the
structure of the chelifori and, finally, the armature of the false
legs and the form of the caudal segment. The genus
Barana. established by Dohrn, appears, in some respects,
to approach the present type still closer than the
preceding genus; and the one of the species B. castelli,
especially, shows in its external habit an unmistakable
resemblance to tile species of the genus Aschorynchus,
whilst the second species. H. arenosa, reminds in this
respect more of the genus Eurycyde. There are, however,
certain features that appear to separate both those species
from the genus Eurycyde as well as Ascorhynchus, and
which forbid their union with any of those genera. Besides
the species more particularly described hereafter. 3 species
from the Challenger Expedition, described by Hoek,
pertain to it, and a form from Japan described by Bohm,
under the .appellation Gnamptorynchus ramipes, has also
been referred by Hoek to this genus. The number of the
species is thus, at present, not less than 5 altogether.

Specific Characters. Body narrow cylindrical, with
-relatively short and widely separated lateral processes.
The 3 foremost segments with the posterior part elevated,
and continued into a pointed process directed upwards; a
similar but somewhat smaller process at the extremity of
each of the lateral processes. Cephalic segment
somewhat longer than the 2 succeeding segments together;
frontal part successively expanded towards the extremity,
wbich£is abruptly truncated. Caudal segment very
narrow, somewhat bent downwards. Ocular tubercle quite
in front, bluntly rounded at the end, with a short
dentiform prominence on each side and without trace
of visual elements. Proboscis of particularly great size,
as long as the 3 anterior segments together, strongly
tumeficated at the middle, almost piriform and folded
under the belly. Chelifori about half as long as
the cephalic segment, scape single-jointed, hand, in fully
