Zoogeographical Investigations in Southern Greenland. 369 
3A. Endemic West Greenland (and Eastern American) species -- the 
corresponding “American” species. 
(K. St., Danmark Exped. p. 582; Conspectus p. 419). 
To this group belong 24 (21) Crustacea (Ianthe libbeyi Ortmann 
erased as bemg synonymous with Ianira tricornis Kr.); the “American” 
fauna including Chionoecetes opilio, Spirontocaris Fabricii, Sp. maci- 
lenta, and Eudorellopsis integra. In addition, we have here to add the 
new species Halirages bispiosus n. sp. Of Echinodermata there are 
3 (Asterias polaris, Ophioglypha nodosa, and A. Stuwitzi) which are 
only found in East-American and W. Greenland waters. 
Of these 27 (24) species, the “Rink” has only found 8, viz. Spiron- 
tocaris microceros, Metopa groenlandica, M. carinata, Paramphithoé 
Boeckii and Halirages bispinosus, and (of American species) Chionoe-: 
cetes opilio, Spirontocaris Fabricii, and Asterias polaris. Of these, Chio- 
noecetes has not hitherto been found S. of abt. 664%4° N. and Paramphi- 
thoé Boeckii not S. of Godthaab (abt. 64° N.). The new Halirages bi- 
spinosus was only found in one place. 
3B. Endemie Greenland species. 
(K. St., Danmark Exped. p. 584; Conspectus p. 419). 
Of Crustacea, 5 species belong here, of which two are “American” 
viz; Nectocrangon lar and Spirontocaris groenlandica. Of Echinoder- 
mata the only one falling to this group, is Pedicellaster palaeocrystallus. 
This group is in the “Rink” material represented by the two “Ame- 
rican” species and Amphithopsis megalops. 
3C. Aretic littoral species, found from Greenland to Spitzbergen or 
farther east, but not N. of Siberia, and in Norwegian waters not S. of 
Finmark. 
(K. St., Danmark Exped. p. 584). 
To this group belong 36 (27) species of Malacostraca and Pycno- 
gonida, besides the following 6 (3) Echinodermata: 
Trochoderma elegans ?Stichaster albulus 
?Solaster glacialis ?Pedicellaster typicus 
— _ squamatus: | Amphipholis Torelli 
In addition, the group should also include the following Echino- 
dermata, which may be called “American” as they are also found on 
both sides of the American continent. 
Chirodota laevis 
Kupyrgus scaber 
Cucumaria calcigera 
Of these 47 (33) species, the “Rink” has only taken 12, viz; Sclero- 
crangon boreas, Aristias tumidus, Anonyx nugax, Dulichia spinosissima, 
LIIl. 24 
Henricia sanguinolenta 
?Pteraster obscurus
