COPEPODA 



47 



Parasitism. In several specimens the body cavity was partly filled with a nematod, which 

 was very distinct through the skin on account of its white colour; this parasite was observed in a young 

 female from Thor St. 153, in 5 f!j> from St. 183 and in one from St. 82, and mag. sci. Hj. Ditlevsen 

 has kindly informed me that it is a larval stage, the exact determination of which is impossible on 

 account of bad conservation.

 of Iceland.

The Thor Expedition has taken this species at about 12 stations in the Atlantic south and 

 south-east of Iceland. Only at the following 6 stations more than single specimens (generally adult 

 females) were found.

In Denmark Strait the Ingolf did not take any specimens, but the Thor brought it home from 

 the following stations.
