held on the afternoons or evenings of such Thursdays from 

 jVoveinber to June inclusive as the Council may decide. 



Due notice of the days and hours of meeting shall be given 

 to erery Fellow whose address is known. 



The President explained that Prof. G. C. Bourne, the Zoological 

 Secretary of the Society, had, in consequence of the war, lost his 

 demonstrators, and therefore a much heavier share of wok had 

 fallen upon him, rendering it impossible for him to attend the 

 evening meetings, though he hoped still to attend the Councils. 



The Rev. T. R. R. Stebbixg hoped that it might not be deemed 

 inopportune if he ventured to congratulate the President on his 

 recent receipt of the Darwin Medal of the Royal Society for 

 his researches in heredity. These remarks were warmly applauded 

 by the meeting, and the President briefly acknowledged his 

 pleasure in the congratulations thus expressed. 



Mr. A. J. WiLMoTT, F.L.S., gave an account of the discovery 

 of Hydrilla verticillata, Casp., by Mr. Pearsall, in Esthwaite 

 Water, a small lake to the west of Windermere; illustrating it 

 by specimens under the microscope. 



Mr. James Groves and Mr. T. A. Dymes contributed further 

 remarks, and Mr. Wihnott replied to the questions raised. 



Mr. C. H. Wright, A.L.S., then gave a sunnuary of his paper, 

 " The Mosses and Hepaticse of West Falkland Islands, from the 

 collections of Mrs. Elinor Vallentin." Having made a collection 

 of phanerogams and ferns, which formed the basis of a paper 

 published in the Journal of this Society, Botany, vol. xxxix. 

 pp. 313-339, Mrs. Vallentin returned to the Falkland Islands 

 and made collections of the lower Cryptogams. The present 

 paper contains the determinations of this collection and atten)pts 

 to bring together the information previously published on other 

 collections. 



The paper was illustrated by specimens and coloured drawings 

 made by Mrs. Vallentin ; and the lantern-slides exhibited were 

 lent also by her. 



Mr. H. N. Dixon and Dr. Otto Stapf, Sec.L.S., spoke on 

 items connected with the topics raised in the paper, and the 

 author replied.

 ptera of the West Indies," which was read on behalf of the 

 author by the General Secretary.
