8 SJÖSTEDTS KILIMANDJARO-MEEU EXPEDITION. 21: 2. 



researchs about the stabilily of this characler will probably give reason for a more nat- 

 ural combination between the genera. I have made numerous examinations in this 

 matter but the time and the space do not permit of my giving in this paper the results 

 I have reached. 



I shall here only give a survey over the essential morphological characters of the 

 numerous genera belonging to the subfamily: Oniscinae. 



The numbers below refer to the following papers, which contain contributions to 

 the systematic of the Oniscinae.
