June 20th. — Mr. C. B. Clarke, F.R.S., President, in the chair. 



Mr. George Massee was elected a Fellow of the Society. 



Mr. F. Enock exhibited and made some remarks upon a living 

 specimen of an aquatic hymenopterous insect, Polynema natans, Lubbock. 



Messrs. E. Baker and C. Reid exhibited some rare plants from the 

 limestone hills, Co. Kerry, including Pinguicula grandijiora, Lam., con- 

 trasted with P. vulgaris, and Saxifraga geum contrasted with S. wnbrosa, 

 with a view of determining their value as subspecies or geographical races. 



Mr. Carruthers exhibited some feathers of a Cuckoo taken at Whit- 

 church, Shropshire, on May 23rd last, amongst which were some moulted 

 feathers which were held connected with the new feathers which had 

 replaced them by means of the barbed seed-capsules of a subtropical grass, 

 Cenchrus echinatus. 



On behalf of Mr. S. Loat, there was exhibited a Cuckoo's egg taken 

 from the nest of a Hedgesparrow, together with five white eggs of that 

 species, an abnormality not often met with. An examination of these 

 eggs under the microscope showed that in regard to the texture or grain of 

 the shell they agreed with eggs of the Hedgesparrow, and not with those 

 of the Robin, of which white varieties are not so rare. 



Mr. George West then gave the substance of a paper on some North 

 American Desmidiece, describing the characters of several new species with 

 the aid of specially prepared lanteru-slides. 



Mr. A. Vaughan Jennings gave a detailed account of the structure of 

 the Isopod genus Ourozeuktes, upon which an instructive criticism was 

 offered by the Rev. T. R. Stebbing, who was present as a visitor; some 

 further remarks being made by Mr. W. P. Sladen. 



Mr. F. N. Williams communicated the salient points in a critical paper 

 which he had prepared, entitled "A Revision of the genus Silene." 



On behalf of Mr. E. R. Waite, Prof. Howes gave an abstract of a well- 

 illustrated paper on " The Egg-cases of Port Jackson Sharks," and exhibited 

 several spirit specimens in further elucidation of the subject. 



This meeting terminated the session.
