previous visits, the explanation of its apparent absence was 

 perhaps the somewhat ungenial conditions obtaining at the time 

 of the excursion. A Roe-Deer was seen in Cleij'horn Woods. 



Mr. D. A. Boyd reported that specimens of Trichoniscus 

 pusillus, Brandt, one of the terrestrial Isopoda, and Tomocerus 

 tridentiferus, Tullb., one of the Collembola, were observed under 

 rotten wood in moist places. Most of the rarer plants recorded 

 at former visits to the district were again observed. Among the 

 Mosses obtained were specimens of Hypnum Schreberi, Willd., 

 with capsules. Thirty-five species of Fungi were noted, among 

 which were Polystictus radiatus, Fr., found on dead branches of 

 Alnus glutinosa ; P. abietinus, Fr., on a dead trunk of Pinus 

 sylvestris ; and Grandinia granulosa, Fr., on dead wood. The 

 Microfungi are included in a separate report. 



Loch Riddon, 23rd May, 1907. — Mr. Alexander Ross, 

 conductor, reported that probably the threatening nature of the 

 weather had accounted for the small number — four in all — who 

 took part in this excursion ; but the smallness of the company in 

 no way detracted from enjoyment of the beautiful scenery for 

 which the district is famed. From Colintraive for about a mile 

 and a-half on both sides of the road are plantations of young 

 trees, mainly oak, the varying colours of whose opening foliage 

 make a fine picture. Further on. birch is the prevailing species. 

 Just where the road turns up Loch Riddon, the highest elevation 

 in this part is attained. A splendid view of the Kyles of Bute 

 is here obtainable. Right below, and stretching southward, are 

 the narrows, where the water makes its way between low-lving 

 and dangerous-looking islands. Extending northward, in all its 

 grandeur, is Loch Riddon, a narrow gulf shut in by rugged and 

 precipitous mountains. Attention was directed to a small and 

 inconspicuous island, Eilein Dheirrig, or Eilein Dubh, situated 

 near the mouth of the loch, which recalls the unsuccessful 

 rebellion of 16S5, and the part played therein by Archibald, 

 ninth Earl of Argyll. 



At the head of the loch, and towards the roadway on the 

 west side, are some fine specimens of Beech and Fir. 

 Ormidale was reached in time to allow of the exploration of 

 Craig Burn, which tumbles down a rugged, rock-strewn course.
