DISTRIBUTION OF THE SPECIES. 
1. Bottom Organisms. 
(Crustacea, Pycnogonida, Echinodermata. ) 
As in the Danmark Expedition, I have taken 200 m. as the limit 
between the littoral zone and the deeper portions. The littoral zone is 
further divided into an algae belt (0—35 m.) and a non-algal (35—200 m.).
