Exemplarer af denne eiendommelige og interessante 
Schizopode blev under Expeditionens tste Togt indsamlede 
ved Huso paa 40 — 60 Favucs Dyb. Den er foruden ved 
Gorges Vest- og Sydkyst observeret ved Shetlandsoerne af 
Norman ( Oenomysis alata), og jeg liar nylig liavt Anled- 
ning til at undersoge 3, under “Challenger” Expeditionen 
udenfor det gode Haabs Forbjerg indsamlede Exemplarer, 
der i ingeri Henseende skiller sig fra den nordiske Form. 
Fam. 2. Euphausiidse. 
37. Nyctiphanes norvegica, (M. Sars). 
Mine Undersogelser af det sserdeles righoldige under 
Challenger-Expeditionen indsamlede Materiale af Euphau- 
siider bar overbevist mig om, at dennef-Forni ikke er nogen 
segte Thysanopoda, hvorimod den noie slutter sig til en i 
det australiske Hav forekommende Form, som noiere vil 
blive beski*even i min Report over Challenger-Expeditionens 
Schizopoda. Jog bar derfor for begge disse After troet 
at maatte opstille en ny Slmgt, Nyctiphanes. 
Nreroerende smukke Art blev under vor Expedition 
observeret ]iaa Here Steder i det jaabne Hav udenfor vor 
Kyst, svommende lige i Overfladen af Vandet, som oftest 
dog kun i yngrc Exemplarer. Paa en'af Stationerne (75), 
V at Namsenfjord, var den tilstede i saadanne enorine 
Masser, at Soen paa enkelte Steder antog en brunlig Farve. 
Arten er udbredt langs vor bele Kyst og nordlig til 
Grordand, Nordamerikas 0stkyst og den murmanske Kyst. 
Det er muligt, at den af Bell observerede britiske Form, 
Thysanopoda Couchii er identisk med nservaerende Art.

Specimens of this peculiar and interesting Schizopod 
were collected, on the 1st cruise of the Expedition, off 
Huso, at a depth ranging from 40 to 60 fathoms. Besides 
the west and south coasts of Norway, the animal has also 
been observed off the Shetland Islands, by Norman {Cteiio- 
mysts alata), and I have recently had opportunity of ex* 
amining 3 specimens collected on the “Challenger” Ex- 
pedition off the Cape of Good Hope, which in no respect 
differ from the Northern form. 
Fam. 2. Euphausiidse. 
37. Nyctiphanes norvegica, (M. Sars). 
My investigations of the exceedingly abundant material 
ot Euphausiidm collected on the “Challenger” Expedition, 
have convinced me that this form can not be a true Thys- 
anopoda, while, on the other hand, it closely approximates 
a species occurring in the Australian Sea, to be described 
in detail in my forthcoming Report on the Schizopods ot 
the “Challenger” Expedition. Hence, I have seen fit t° 
establish for these two species a new genus, viz. Ny '($' 
phones. 
The present beautiful species was observed on the 
Norwegian Expedition in several localities, at a consider- 
able distance from the coast, swimming about at the 
surface of the water; as a rule, however, exclusively young 
individuals. At one of the Stations (Stat. 75), west of 
the Namsenfjord, the animal occurred in such profusion, 
that the sea, in some localities, had a peculiar brownish 
tint. 
The form is distributed along the whole of the Nor- 
wegian coast, extending as far north as Greenland, the 
east of North America, and the Murman coast. Maybe, 
the British form, Thysanopoda Couchii, observed by Bell, 
is identical with the present species.
