This species is thus very common at depths of from some few metres 
down to abt.50 m. For larva se p. 256.

This species is thus common in shallow water and down to abt. 
400 m., being most frequently found, however, from the surface to 
abt. 50 m.

18. Spirontocaris groenlandiea Fabr. 
Conspectus р. 34.

St. 79, 30—50 m., 2 spec. ; St. 89, 16—17 m., 2 spec., 1 young with larva 
of Phryxus abdominalis. — Skovfjord St. 156, 70—140 m., 1 spec. 
This species, otherwise extraordinarily numerous in all Greenland 
waters, is thus, as regards the area here investigated, not nearly so 
common as might have been expected. 
Besides the localities other than Greenland mentioned in the Con- 
spectus, the species has also been taken at Awatscha (Japan?) (Barss: 
Ostasiat. Decap., 1914, p. 45). 
For young form, vide infra p. 264. 
19. Spirontocaris microceros Kr. 
Conspectus p. 37. 
Bredefjord St. 48, 1 spec. 
The finding of this species is one of the most interesting results 
of the expedition; the specimen in question is somewhat defective, but 
the determination nevertheless certain.
