Lenimiea Jluviatilis, Agardh, a fresh-water alga from Bardrain 

 Glen, Gleniffer, was exhibited by Mr. S. M. "Wellwood. This 

 species is not common in Britain, but it has been found several 

 times in the West of Scotland. The specimens exhibited 

 consisted of sexual shopts or '• fronds." Mr. Wellwood gave the 

 following brief general outline of the life-history of a Lemanea 

 from the observations of Professor Atkinson, of the Alabama 

 Polytechnic Institute, U.S.A. : — '• On the germination of the 

 carpospore a series of cells are formed, w^iich may consist of short 

 polyhedral cells or confervoid filaments. This is the first form 

 of the protonema, and is described as the prostrate form. This 

 form is permanent, and gives rise to the secondary form, which 

 bears a striking resemblance to a Chantransia plant, but produces 

 no gonidia. In Batrachospermum the secondary stage is also 

 Chantransia-like, but bears gonidia, the non-sexual spores of which 

 may propagate the form indefinitely without developing a sexual 

 shoot of the Batrachospermum. In Lemanea the Chantransia 

 form is sometimes developed directly from the spore. The last 

 form of the Lemanea plant is the sexual shoot or ' frond.' These 

 ' fronds ' originate as special lateral shoots from the Chantransia 

 form. The individual shoot is simple, or bearing short branches 

 sparingly. It consists of a single row of tubular cells, and
