PROCEEDINGS OF THE SOCIETY. 129 



ANNIVERSARY MEETING 



Held ox the 19th of January, 1910, at 20 Hanoyer Square, W. 

 Sir Edwin Ray Lankester, F.R.S., etc., President, in the Chair. 



The Minutes of the Meeting of December 15, 1909, were read and 

 confirmed, and were signed by the President. 



Messrs. H. Taverner and C. D. Soar were duly elected as Scrutineers 

 of the Ballot for the election of Officers and Council of the Society for 

 the ensuing year. 



The List of Donations, exclusive of exchanges and reprints, 

 received since the last Meeting, was read, and the thauks of the Society 

 were voted to the donors. 



Attention was called by Mr. F. Shillington Scales to a projection 

 lantern, presented by Mr. J. W. Ogilvy, provided with a self-regulating 

 arc lamp of 3000 candle power, and having a neat and convenient 

 arrangement for taking any size slide. As it could be coupled on to 

 the electric supply of that room, it was likely to be of much service to 

 the Society, and was not only a very welcome donation, but one for 

 which they felt greatly indebted to the donor. 



On the Motion of the President the special thanks of the Society 

 were voted to Mr. Ogilvy for his valuable addition to their apparatus. 



Mr. C. F. Rousselet said he was exhibiting under a Microscope 

 in the room some specimens of a rare species of Pedalion, P. oxyure 

 Sernow, which he had found in material collected by Dr. Cunnington 

 and C. Boulenger in the brackish lake Birket Qarun, in the Fayum 

 Province of Egypt. It would be remembered that the first species of 

 this genus, remarkable amongst all other Rotifera, for the possession of 

 six arthropodous limbs, P. minim, was discovered in 1871 by Dr. C. T. 

 Hudson, at Clifton, near Bristol. A second species, P.fennicum, was 

 found by Dr. Levander, in Finland, in 1892, and the third species, 

 P. oxyure, now exhibited, was found by S. Sernow in 1903 in the Aral 

 Sea. This same species was also found last year by Professor von Daday 

 in material collected in Turkestan, and named by him P. mucronatum, 

 which name, therefore, is a synonym, and cannot stand. P. oxyure most 

 nearly resembles P. fennicum, but differs from it in the fact that the 

 posterior end of the body is drawn out into an elongated hyaline 

 projection. 



The President said it was extremely interesting to hear of this find, 

 and hoped they would hear more of it, his opinion being that Pedalion 

 was the most wonderful of all the Rotifers, as having legs and striated 

 muscles to work them, and hairs on them resembling those of Crustacea. 



Thanks were voted to Mr. Rousselet for bringing this specimen for 

 exhibition.
