Cristatella Mucedo

Abstract

As this very beautiful polyzoon is generally believed to be nearly, if not quite extinct in ponds in the neighbourhood of London, I should like to record the fact that on November 19 last, I took a fine specimen two inches in length, which is still living. The colony was packed with statoblasts, most of which are now discharged. It was not perfect when taken, and has again divided since it has been in a small aquarium.
