aware it is the only find of this species known from within the 
Scaw. The species under consideration must be noted as new to the 
Danish fauna. 
Prionospio Steenstvupi Mgrn. 
“Dana“ St. 2889, 1 spec. 
Only one specimen was secured by the “Dana“, originating 
from the same locality as the preceding species. 
Magelonidæ 
Magelona papillicovnis (O. F. M.). 
Samsø belt. Fast of “Pughavn“. 4 m. 24.VI.12. Bl eg vad. 
2 spec. 
In 1920 the genus under consideration was stated to belong to 
the Danish fauna as Eliason mentions M. rosea Moore as taken in 
the South-Eastern part of the Kattegat. 
It is quite interesting that the two specimens at my disposal 
and originating from the western part of the Kattegat, belong to M. 
papillicornis. The bristles of the ninth setigerous segment thus 
terminate in a bulbous tip and are in shape perfectly agreeing with 
the figures of Mcintosh from 1878 (65). The two specimens are 
put down on the list from the Danish Biological station (76) p. 25 
as Spionidæ. 
Disomatidæ 
Disoma multisetosum Ørsted. 
Nyborg Fjord. 27.VIII. 1920. Blegvad. 4 spec. 
As the distribution of this interresting form is very little known 
I notice here the find from the area of the Great Belt. It is be- 
sides not astonishing that the species enters a water the salinity 
of which is so low as that of Nyborg Fjord, as it has been re- 
corded from the western parts of the Baltic.

Civvatulus tentaculatus Mont.
