ARGYLLSHIRE EXCURSIONS. 149 
Species of fresh water algae belonging to the genera Microspora 
and Cladophora were got in the mountain burns, while in bog 
pools several species of Mougeotia, some in the conjugating stage, 
were collected. 
The ornithologists had the pleasure of seeing the ptarmigan 
(Zagopus mutus, (Montin)) on the “Cobbler.” The most 
interesting of the summer birds observed in the valley were the 
whinchat (Pratincola rubetra (Linnzus)), the wood wren 
(Phylloscopus sibilatrix (Bechstein) ), and the tree pipit (Anthus 
trivialis (Linnzus) ), 
The entomologists confined themselves to the ground on the 
right bank of the Loin river. Their captures, owing to the state 
of the weather, were mainly tipulidz, of which the following are 
recorded :— 
DIxa MACULATA, Mg. ERIOPTERA TZNIONOTA, Mg. 
LIMnosia NEBECULOSA, Mg. LIMNOPHILA MEIGENII, Ver.
