in small crustacea, much Ticher in several respects than for instance 
the gulf of Naples and the harbour of Messina, but our knowledge 
of this fauna is still more insignificant than our knowledge of the 
littoral microfauna in the seas at America, Asia and Australia! 
I am able to set forth a few supplementary remarks on the occur- 
rence of the Asterocheridæ. 
In bottom material — treated with a sieve clothed with silk- 
gaze (no. 7) and preserved in spirit — secured by the »Ingolf'- 
Expedition in various stations in the southern part of the Davis 
Strait I have found numerous Copepods and among them a number 
of Asterocheridæ, at least about five species belonging to various 
genera. At least the major part and perhaps all these Copepods 
have lived at the bottom, and the depths noted for the stations are: 
318, 582, 1190 and 1435 fathoms. — In bottom material secured 
by Dr. Th. Mortensen two years ago in various localities in the gulf 
of Siam from depths between 1 io 30 fathoms I have found several 
forms of Asterocheridæ. — I am inclined to believe that the family 
contains several hundreds of species, and that they can be found in 
all seas from the shore to depths of at least 1500 fathoms.
