is on the contrary most frequent, reaching a maximum of 303,600 ind. pr 1, but only at 

 a depth of 60 m. As at other stations it is accompanied by Ch. diadema, both having to 

 a large extent passed to the sporal stage, especially the latter species. Also Thalassio- 

 sira Nordenskiöldii is tolerably common under the 30 °/oo limit.

There is a distinct heaping up of peridinians in the 20 — 30 m layer, that may be 

 put in correspondance with a similar, but still richer, accumulation at the same depth 

 at the foregoing station 6.
