shown by*C'heviakoff to be due to a secretion of filaments of this 

 nature ; but here, of course, the question of the surface-film 

 does not arise. 



Mr. Rousselet read a paper on " Triarthra hracldata^' a new 

 species of Rotifer which had been found on Putney Common, 

 and had also been sent to him from the North of Ireland, 

 •concluding with some remarks on the spines of the Triarthradae 

 in general, and the relation of these rotifers to the suiface-fihn. 

 The paper was illustrated by drawings and by specimens exhibited 

 under the microscope, 



Mr. Scourfield said he could confirm the observation as to 

 the adhesion of these rotifers to the surface-film of water, but 

 would like to ask if Mr. Rousselet had ever seen them suspended 

 from it in such a way as to suggest that they were deliberately 

 making use of the surface-film for support. 



Mr. Rousselet said he had not seen this in the case of the 

 rotifers just described, but he had, he thought, seen Philodina 

 suspended in this way. 



A hearty vote of thanks to Mr. Rousselet for his paper was 

 unanimously carried. 



Mr. Karop said they had another paper on the agenda by 

 Mr. Merlin " On the Spermatozoon of the Rat." This was no 

 doubt a very excellent piece of work, which he thought it would 

 be a pity to read at that hour ; it was therefore proposed to 

 defer it to the next meeting. 



The proceedings then terminated with the usual conversazione.
