Reports of excursions to Neilston Pad (see page 124), West 
Kilbride (see page 124), Queen’s Park (see page 125), and Gare- 
lochhead (see page 125) were read. 
Mr. Charles Hogg exhibited the King Bird of Paradise (Cicin- 
nurus regius (Linn.)) and two Corncrakes (Crea pratensis, Bechst.). 
Lemanea fluviatilis, Agardh, a fresh-water alga from Bardrain 
Glen, Gleniffer, was exhibited by Mr. 8. 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 shoots 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, which 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
