gives, amongst other interesting information, another record of 

 the nesting of the Crested Tit. This is reproduced as follows 

 from The Field of 24th April : " In reply to Mr Pettitt's inquiry, the 

 Glengarry referred to is in Inverness-shire. It lies between Loch 

 Oich and Loch Hourn. The fir woods lie on the south side of 

 Loch Garry, and are, roughly, six miles long by one mile wide. 

 These woods are part of the old Caledonian Forest, the remains 

 of which (old fir roots) show that at one time it extended right 

 across Scotland. Another similar fir wood may be seen in Glen 

 Mallie, Loch Arkaig side, and is of even larger extent. Between 

 the years 1889 and 1906 the late W. Cameron (gamekeeper) used 

 to find the Crested Tit nesting there. I have not been there 

 since 1906, but there were several pairs there at that time. I 

 think Mr Kearton got his photos of the Crested Tit there. 

 I think this bird is commoner than is supposed, as it is easily 

 overlooked in those large woods." 



Fauna of Clyde Sea Area. About 160 species of animals, 

 almost all invertebrates, have been recorded by Louis P. W. Renouf 

 as occurring on the area of the Ascog Patches on the eastern side 

 of Bute {Glasgoiv Naturalist, vol. viii., 1920, p. 113). The list 

 contains the names of representatives of Sponges, Coelenterates, 

 Molluscs, Worms, Polyzoa, Crustaceans, Echinoderms, Tunicates, 

 and a few Fishes and Protozoa; while it makes no pretence to 

 completeness, it affords evidence of what variety a small area 

 may yield in a few days' dredging, and makes a useful contribution 

 to our knowledge of the detailed distribution of the Clyde fauna. 



Land and Freshwater Molluscs of Lanarkshire. A 

 valuable contribution (which now appears after his death) has been 

 made to the knowledge of the Molluscan fauna of Lanarkshire by 

 W. Denison Roebuck {Glasgotv Naturalist, vol. viii., 1920, p. 131). 

 His list of species, made up from the examination of many individual 

 collections, includes 58 species, of which 8 are slugs, 23 land and 

 27 freshwater shells. This represents on the whole a poor 

 Molluscan fauna, but the absence of several common species 

 such as the Great Slug, Li/nax inaximus, from the list suggests 

 that further collecting might result in the discovery of several 

 additional species.
