 and 2 of the „Bulletin". The greater part of the content is of 

 hydrographical interest, but in No. 2 plankton-iists occur. 

 At the hydographical stations samples of plankton are collected 

 by means of different nets; the determinations of these plankton- 

 samples are published in the above-mentioned bulletin in tabular 

 form the comparative abundance is indicated by means of ordi- 

 nary Symbols. No. 2 of the bulletin contains lists 1. from the
