288 PROCEEDINGS OF THE 



He proposed, therefore, to mention briefly what seemed to be 

 the most striking characteristics of the various forms. 



Mr. Bryce stated that he had only seen one of the species or 

 varieties now described, but he was pleased to note that since 

 his return to Scotland Mr. Milne had already found in Aberdeen- 

 shire three of the species which he had previously discovered in 

 Cape Colony. Mr. Bryce then briefly described various species of 

 the genera — Macrotrachela, Habrotrocha,Mniobia, Scepanotrocha, 

 Pleuretra, Otostephanos and Adineta. 



In conclusion, Mr. Bryce stated that Mr. Milne hoped to furnish 

 as an appendix to this paper a list of all the Bdelloida he had 

 observed in South Africa. When this is prepared and the results 

 collated with the late James Murray's list of the species identified 

 and discovered by him in the same region, it may be expected that 

 the combined record of South African Bdelloida will be much 

 longer than can yet be shown for any other country in the world, 

 Great Britain alone excepted. 



The President, in commenting on the paper, said they were all 

 greatly indebted to Mr. Bryce for the care and pains he had taken 

 in bringing it before them. He (the President) had had the 

 advantage of seeing the plates illustrating it, which were very 

 beautiful and added greatly to the interest. He thought, how- 

 ever, it would be more convenient if the measurements of micro- 

 scopic objects were given in the metric system, which has now 

 superseded the statement of size in fractions of the English inch. 



A considerable amount of discussion ensued on this subject. 

 Mr. Bryce said he was quite in accord with the President in the 

 matter, and believed he was the first in this country to state the 

 measurement of Rotifera in microns. 



The Chairman proposed a hearty vote of thanks to the author, 

 and to Mr. Bryce for reading the paper, which was unanimously 

 agreed to by all present. 



At the 520th Ordinary Meeting of the Club, held on 

 November 28th, 1916, the President, Prof. Arthur Dendy, D.Sc, 

 F.R.S., in the chair, the miimtes of the meeting held on 

 October 24th, 1916, were read and confirmed.
