PROCEEDINGS OF THE SOCIETY. 



MEETING 



Held on the 15th of June, 1910, at 20 Hanover Square, W., 

 Professor J. A. Thomson, M.A. F.R.S.E., President, in the 

 Chair. 



The Minutes of the Meeting of May 25, 1910, were read and con- 

 firmed, and were signed by the President. 



The following Donation to the Society was announced : — 



From 

 Report of the British Association, Winnipeg, 1909. (8vo, \ sir Frank Crisp 

 London, 1910) .. .. .. .. .. .. .. / e ' 



The thanks of the Society were voted to the donor. 



The President said that he had the pleasure of exhibiting two in- 

 teresting and beautiful slides of a rare Synaptid sent by Mr. M.J. Allan, 

 Geelong, Victoria. One slide showed the entire animal well cleared ; 

 the other showed the characteristic spicules, which have the form of 

 hoops and complex wheels. It was interesting to recall the fact that the 

 complex wheels in these Echinoderms had a gradual development from 

 very simple, almost spherical, corpuscles. Mr. Allan had found the 

 Synaptid in some abundance in Cario Bay, and, noticing some pecu- 

 liarities, had regarded it as quite new. He had even given it a pro- 

 visional name, Amentum hamulus. This was, however, unnecessary, for 

 the specimen turned out to be the well-known, though rare, Trochodota 

 dumdinensis (Parker), first described by Professor Jeffery Parker. 



The President went on to say that he had sent the slides, which 

 struck him as interesting, to two well-known authorities on Holothuroids, 

 Professors R. Koehler and C. Vaney, of Lyon, joint authors of numerous 

 important memoirs on Echinoderms. With characteristic courtesy, 

 Professor Vaney had at once supplied the desired identification, and had 

 indicated that the specimen was of considerable rarity and much interest. 

 He expressed his desire to have a specimen, if there was any duplicate 

 available. The Society was indebted to Professor Vaney for his identifi- 

 cation of the specimen, and to Mr. Allan for sending it. He hoped that 

 Mr. Allan would not be too much disappointed at learning that what he 

 had found was not new. One of the services that the Society could render 

 was to secure the identification of specimens by experts, and it was to be 

 hoped that those benefited would remember the expert's desire for 

 specimens.
