SPECIMENS EXHIBITED. 



Mr E. R. Alston exliibited two specimens of the bank vole 

 (Arvicola pratensis of Baillon) from the Upper AVard of Lanark- 

 shire. The most northern locality in Britain hitherto recorded in 

 connection with this species appears to be Roxburghshire, where 

 it is not uncommon, and Mr Wheelright states that it occurs in 

 Scandinavia, reaching even to the Arctic Circle. Mr Alston had 

 taken six specimens near Lesmahagow, and stated that this little 

 animal would be found common in other parts of Scotland. He 

 likewise made some interesting observations on the habits of the 

 species, as observed by himself. 



Mr David Robertson exhibited specimens of a new Entomos- 

 tracan, which he had discovered in the Paisley Canal, near 

 Glasgow, and for which Mr G. S. Brady had proposed the name 

 Candona simplexr' These he had found to be common in the 

 habitat referred to. As an instance showing how little this 

 and nearly allied species are aflfected by the condition of the 

 Avater in which they live, Mr Robertson mentioned the curious 

 fact, that 'he had this season observed swarms of these minute 

 organisms at the end of the wharf in Egiinton Street, where the 

 water is hot by the refuse supplies from neighbouring factories, 

 the surface clouded with patches of oil, and wdth foul gas from 

 below. In the mud brought up, which was quite black and slimy, 

 being mixed with every conceivable kind of rubbish, and having 

 a very offensive odour, he had found great numbers of Ostracoda, 

 particularly Cypris compressa, plump and clean, as if reared in a 

 habitat of the greatest purity. 



Dr Dewar exhibited an albino variety of the common guillemot 

 (Uria troile) which had been shot last month in the Kyles of Bute. 

 The specimen, which was perfectly white, was interesting from the 

 fact of albinoes being particularly rare among sea bii'ds. 



Mr John Young exhibited specimens of Balamis vulgaris, ob- 

 * Now named by Miiller, Candona detecta.
