Nylig er sanime Form under den franske Expedition 
fundet meget almindelig paa de storre Dyb i Biscayerbugten. 
De to under vor Expedition erholdte Exemplarer op- 
toges i Trawl nett.et circa 20 Mil udenfor vor Yestkyst 
(Stat. 10 ) fra et Dyb af 220 Favne. 
Dens hidtil bekjendte geografiske Udbredning straekker 
sig saaledes igjennem circa 20 Bredegrader. Hvis Stimp- 
sons Art skulde vise sig at vsere identisk ined vor. bliver 
Udbredningen selvfplgelig endnu betydelig storre. 
Overalt er den kun fundet paa Dybder over 100 
Favne. og den er derfor at betragte som en segte Dybvands- 
form, noget. der ogsaa paa Forhaand vil kunne sluttes af 
enkelte Organisationsforhold, navnlig de lidet udviklede 0ine 
og disses lyse Pigment. 
De physiske Forhold. hvorunder den forekommer, synes 
endelig at vise, at den er en mere sydlig Form, der alene 
tilhorer den tempererede Area, men er ganske fremmed 
for den kokle.

Sir Wyville Thomson’s well-known work, “The Depths of 
the Sea,” under the name of Amathia Carpenteri. 
A short time since, the same form was met with on 
the French Expedition, occurring very abundantly through- 
out the great depths in the Bay of Biscay. 
The two specimens obtained on the Norwegian Ex- 
pedition were brought up in the trawl-bag, about 20 miles 
off the west coast of Norway (Stat. 10), from a depth 
of 220 fathoms. 
Hence, its geographical distribution as hitherto known 
comprises about 20 degrees of latitude. Should Stimpson s 
species prove to be identical with ours, the distribution is 
of course much more extensive. 
In every locality, this crustacean has been met with 
in depths exceeding 100 fathoms, and must therefore be 
regarded as a true deep-sea form, which could, indeed, be 
presumptively inferred from certain characteristics of organ- 
ization, in particular the slight development of the eyes 
and their light pigment. 
Finally, the physical conditions under which the animal 
occurs would apparently distinguish it rather as a southern 
form, exclusively belonging to the temperate and wholly 
unknown in the cold area.

Specific Character. — Body comparatively robust, 
beset with scattered fasciculi of bristles. Margin of front, 
in the middle, but slightly projecting. Eyes oblong clavi- 
form, shorter than the frontal margin. Chelipeds very un- 
equal, ciliated; right arm much larger and more power- 
fully developed than left, with the 5th segment (the 
wrist) comparatively thick, and densely beset with spiniform 
tubercles; hand broadly oval, with 3 longitudinal carinse, of 
which the 2 outer ones occupy the edges and are regularly 
and coarsely dentate, whereas the 3rd extends along the 
middle of the upper surface and is more obtuse than 
the two others. Surface of hand between the carinse
