Zoogeographical Investigations in Southern Greenland. 375 
beyond; the species taken nearer the surface will easily be seen from 
the lists on p. 347 (bottom fauna) and p. 354 (plankton). 
1. Bredefjord and Sermilik (chart p. 323). 
Bredefjord, with Sermilik, will here be taken first as the richest 
and best investigated water. With regard to the depths, vide p. 233, 353 
and for hydrographical conditions p. 362. 
The bottom Crustacea taken in this fjord at depths > 200m. are 
as followst?: 
Chionoecetes opilio, x Munidopsis curvirostra, Diastylis Goodsirii, 
Neohela monstrosa, Caprella Rinkii, Calathura brachiata, (Aega ven- 
trosa), Ianira maculosa, I. tricornis, x Eurycope producta, Saccopsis 
Terebellidis(?), x Scalpellum Stroemii. 
The following Pycnogonida were taken at > 200 m.: Pycnogonum 
littorale, Nymphon Stroemi ~ gracilipes, N. macrum, Chaetonymphon 
hirtipes. 
Also the followmg Echinodermata: Heliometra glacialis, x Hathro- 
metra Sarsii, Pteraster hastatus, x Poraniomorpha hispida, x Astro- 
gonium Parelii, Ophiura Sarsi, x Amphiura denticulata, x Ophiacan- 
tha anomala, <x Ophiolebes claviger, Ophioscolex glacialis, x Gorgono- 
cephalus Lamarckii, x Molpadia odlitica, x Laetmogone violacea, Cu- 
cumaria calcigera, Phyllophorus pellucidus, x Psolus valvatus. 
Among the Plankton the followimg species of Crustacea were only 
found at depths > 200m.: x Pasiphaé tarda, x Boreomysis arctica, 
x Scina borealis, (?) Pseudalibrotus Nanseni and Apherusa glacialis, 
i.e. 3 true Atlantic species, whereas the two lastnamed are arctic. These 
two last species were however, with the exception of Apherusa glacialis, 
(Bredefjord, St. 30, Nansen-net 550—450 m.) taken with the ringtrawl, 
so that it is not impossible that they may in reality have been taken 
nearer the surface. : 
This gives, for Crustacea, Pycnogonida, and Echinodermata, 37 
“species in all, of which 14 are true types of Atlantic fauna. 
Two species, Calathura brachiata, and Neohela monstrosa, are 
known from the arctic deep, but cannot be said to be truly arctic; vide 
Group 1. C. p. 366. 
Some species are also found in shallower water, and cannot there- 
fore be certainly classed as Atlantic deep sea forms, viz: 
Neohela monstrosa, Aega ventrosa, Ianira maculosa, Pycnogonum 
littorale, Nymphon Stroemu, N.macrum, Chaetonymphon hirtipes, 
Heliometra glacialis, Ophioscolex glacialis, Cucumaria calcigera, Phyllo- 
phorus pellucidus. 
With regard to these species, vide p. 368. 
The remainder should doubtless most properly be classed as arctic
