In 1933 Dr. G. J. van Oordt together with a number of biological students made an excursion to the Camargue. During that trip he collected some samples of mud from brackish ponds and pools in the Rhône Delta, which collection he entrusted me for further research. At this place I will bring him my renewed thanks for his contribution to nematology. Although the collection was not great, it brought to light some interesting new species. Moreover it allows us to say something about the penetration of marine forms into brackish waters. A comparison of the list of forms given below with the lists I have given from Nematodes found to occur in the former Zuidersea shows that the penetration of marine forms into brackish waters in the Mediterranean is performed in... |

In June 1932 my friend Prof. Dr. G. C. Hirsch made some biological studies at the marine biological laboratory of Palma di Mallorca. He was accompanied by Dr. E. Ries, at that time Rockefeller Fellow. Both did collect for me some samples of marine sediments from which I have picked out the freeliving marine nematodes for further study. In the same year Dr. A. Oosterbaan made an excursion to Ibiza together with some other geological students and brought home from there for me some samples of mud with marine nematodes. The result of the 3 mentioned small collections, of which that of Hirsch is the most important, will be given in this paper. Next to a comparatively great number of typical mediterranean marine nematodes, a restricted number has a more... |
