 tish Hymenomycetous Fungi, Ilydnum n'ujrum and Lactarius contro- 

 versus. 



Mr. Eedhead, F.L.S. , exhibited a specimen in fruit of Ouhifa

 time on tho mainland of Europe), by Mr. "VV. Glassford, at Algeceii-as, 

 near Gibraltar. 



Mr. Busk, Sec. L.S., exhibited, on the part of Sir E. I. Murchison 

 Bart., a specimen of a sort of silky web, found lining the inner sur- 

 face of the hatches of the steamer ' Onward,' which had brought a 

 cargo of Indian corn from Trieste to London. Various suggestions 

 were oifered as to the Insect by Avhich this substance had been pro- 

 duced ; and Mr. Stainton thought it not improbable that it might 

 have been the work of Tinea granella.

 the note by Sir John Lubbock, in No. 43 of the Society's Journal, 

 " On the discovery of Planaria terrestris in England," and calling 

 attention to the fact that he had himself, in his " Observations in 

 Natural History," published in 1866, described the same animal, 

 under the name of " Ground Fluke," as common in damp woods in 

 Cambridgeshire, and expressed his belief of its identity with the 

 Fasciola terrestris of MiiUer. Mr. Jenyns further stated that the 

 animal also occurs in woods about Bath, where many specimens had 

 been collected during last summer.
