For Tiden maa vi saalecles betragte den nedenfor 
nscrmere beskrevne Art som en temmelig isoleret staaende 
Form, der kun har en ijern Affinitet til SI. Pasiphae, men 
som maaske sammen med de 2 oveim;:evntc. erulnu kun 
ufoldstaendigt kjendte middelhavske Former tor danne en 
egen anomal Gruppe af Carider. i enkelte Punkter visende 
en Slags Overgang til Schizopoderne.

Artscharacteristik. Rygskjoldet jevnt hvaelvet, med 
den dorsale Kjol i den forreste Del bevasbuet med 4 6 
smaa T sender. Pandebornet sawdeles kort, med Enden til- 
spidset og den nedre Kant ubevsebnet. 0inene nsesten ko- 
niske, med Spidsen tilrundet og forsynet med opakt hvidt 
Pigment, lste Par Foleres Skaft kort cylindriskt, med 
Basalleddet storst; den ydre Svpbe lamgere og stffirkere 
end den indie, 2det Par Fplcres Blad 1 / 3 lsengere end lste 
Par’s Skaft, bredest paa Midten, med den ydre Kant glat 
og fortil endende med ct tandformigt Fremspring; Svoben 
mere end dobbelt saa lang som hele Legemet. De 2 for- 
reste Fodpar baade i Storrelse og Bygning ens, med Saxene 
lidet fortykkede og Fingrene kortere end Palmen. Sidste 
Led paa de 2 folgende Par forlxenget og afsmalnende, paa 
sidste Par linetei’t og tmt liaaret. Det midterste Haleved- 
bmng i Spidsen noget udvidet og her bevmbnet med 7 Torner, 
bvoraf de 5 midterste or af ens Ltengde, hvorimod de 2 
ydre er over 3 Gan go saa lange og stamkt divergerende. 
Farven intensiv blodrpd. Lsengden indtil 83"™.

Bemaerkninger. Naervaerende interessante og eien- 
dommelige Krebs er fprst opdaget under den 2den tydske 
X ordpolexpedition, men kun i et enkelt Exemplar, som af 
Bucbbolz paa ovenanfprte Sted er kjendeligt beskrevet og 
afbildet. Da Exemplaret maatte saavidt muligt skaanes 
for at kunne tjene som Type-Specimen, har Buchholz selv- 
folgeligt ikke kunnet anstille nogen dybere gaaende anato- 
nu’sk Undcrsegelse af samme og derfor heller ikke kunnet 
skaffe sig noget Kjendskab til Munddelenes Bygning, hvori 
den generiske Forskjel fra Pasiphae er sharpest, og tydeligst 
udtrykt. 
Beskrivelse. Legemets Form er (se Fig. 1 og 2), 
u lig samme hos Pasiphae, temmelig plump og nsesten trind, 
At present, therefore, we must regard the species 
described below as a rather isolated form, exhibiting but 
slight affinity to the genus Pasiphae, and which perhaps, 
more properly, may constitute, together with the above- 
mentioned, still imperfectly known Mediterranean forms, a 
peculiar group of Caridians, marking in some respects a 
kind of transition to the Schizopod type.

Specific Character. — Carapax uniformly arcuate, 
with the dorsal carina, along the anterior part, bearing from 
4 to 6 small teeth. Rostrum exceedingly short, with the 
extremity pointed and the lower margin unarmed. Eyes 
almost conical, with the point rounded off, and furnished 
with an opaque white pigment. Peduncle of 1st pair of 
antennae short, cylindric, with the basal joint largest; outer 
flagellum longer and more powerful than inner; scale of 
2nd pail- of antennae one-third longer than peduncle of 
1st pair, broadest in the middle, with the outer margin 
smooth, and terminating anteriorly in a dentiform projec- 
tion; flagellum more than twice the length of the whole 
body. The 2 foremost pairs of legs precisely similar, 
alike in size and structure, with the chelae but slightly in- 
crassated and the dactyli shorter than the palm. Terminal 
joint on the 2 succeeding pairs elongate and tapering, on 
the last pair linear, and densely clothed with hair. Telson 
somewhat dilated at the point, which is armed with 7 spines, 
the 5 median of one length, but the 2 outer ones more 
than 3 times as long, and strongly diverging. Colour a 
deep blood-red. Length reaching 83"™.

Bemarks. — This interesting and very peculiar form was 
first met with on the Second German North Pole Expedi- 
tion. one specimen only having however been secured, which, 
in the aforecited work, Buchholz has recognizably described 
and figured. The said example having had to be handled 
with the greatest possible care, to admit of reserving it as 
a type-specimen, Buchholz could not of course undertake 
a comprehensive anatomical examination ; and hence he 
failed to learn aught concerning the structure of the oral 
appendages, in which the generic difference between this 
form and Pasiphae is most salient and conspicnous. 
Description. — Form of body, contrary to what is 
observed in Pasiphae (see figs. 1, 2), rather clumsy and
