Abstract
ON July 12, 1944, while collecting planarians in the Cam at Cambridge, we found a small orange-coloured worm in the leaf axils of Glyceria aquatica stems. Afterwards many more were found. The general structure, including the proboscis, showed clearly that it was a nemertine. The only freshwater nemertine previously recorded from Great Britain was a single specimen found by Benham1 in the River Cherwell, of which, however, there is no full description. There is also a single record of a freshwater nemertine from Ireland in Co. Dublin2. The present record is therefore of interest.
