 Of Spongozoa : Pyhjmastia mamiUaris o. f. Muiier, P- hemisphæricnm sare and Sty- 



locordyla horealis Loven- 

 Of Anthozoa, finally, an Actinia aud Funicidina quadrangnlaris pan are new; 



and Kophohelemnon stellifermn o. f. mhUci-, can now with certainty be said 



to beloug to the Danish part of the Skager Rack. 



In all about 40 new species have thus beeu added to the Danish fauna, 

 all from the Skager Rack. For we do not hesitate to class the animals in 

 nearly the whole of the Skager Rack among the Danish fauna, being of the 

 same opinion as G Winther in his »Prodromus Ichthyologiæ Danica Marinæ«, 

 1879, that it is the deepest part of this sea which forms the uatural boundary 

 between the faunas of the countries; aud if we draw the boundary-line in the 

 middle of the very deepest part, all the above-mentioned stations, with the ex- 

 ception of Nr. 9, will fall within the Danish part. After all, however, this 

 questiou of the boundaries is not a very essential one. The main point is, to 

 get acquainted with the fauna of the open Skager EacJc. To this the above may 

 contribute a little, but, certainly, only a little; for it is but occasionally we 

 have got the large as well as the smallest animals, aud the piaces we have 

 investigated are, as yet, too few in number.
