themselves, and presented an elegant object as the festoons and 

 masses gently swayed and bent in the slowly running water. The 

 diatoms proved to be Fragillaria, probably capiiciua, a not very 

 interesting species, being almost without markings ; the only 

 advantage possessed being that it was an opportunity for obtain- 

 ing an almost unmixed gathering of a filamentous species. A 

 fine OsciUato7'ia growing on the bottom close by was most likely 

 0. /rolichii. 



Flumatella was taken in abundance, as were water-mites, and, 

 of course, many species of Entomostraca, and larvae of Diptera. 

 Fresh-water sponge was in masses on the brickwork of a bridge, 

 while tiny specimens occurred frequently on the water-lily leaves 

 and petioles. Ohara in fruit was found. Rotifera were taken in 

 considerable numbers ; the species have not so far been reported. 

 It was a fine afternoon, and the twenty-four members present 

 were quite satisfied with the results.
