EDITOKIAL NOTE. 



On the return of the Expedition the specimens of Nemertea, along with the 

 Annelida, were placed in the hands of Professor W. C. M'Intosh, F.K.S., for 

 description. In the year 1884, however, Professor M'Intosh's time being fully 

 occupied with the Annelida, Professor A. A. W. Hubrecht of the University 

 of Utrecht, was requested to undertake the investigation and description of 

 the Nemertea, and the results of his labours are presented in this interesting 

 and valuable Report. 



The Manuscript was received by me in instalments between the 12th 

 October and 18th November 1886
