42 THE SCOTTISH NATURALIST 



Since writing the above I have received from Misses 

 Baxter and Rintoul the following interesting extract from 

 their journal : — 



i^tJi f/aie 1913, EdenmoutJi. — "An aeroplane passed over 

 us when we were near the Eden ; it put up the birds and 

 they flew off in flocks. The majority we saw were Sheldrake, 

 Oyster-catchers, and Curlew. The Sheldrake and Curlew 

 flew right off in the direction of the sea ; the Oyster-catchers, 

 on the other hand, were more inclined to circle round and 

 settle again on the sand." 



Some Mountain Spiders, including Erigone tiroleusis, 

 L. Koch, from the Tay and the Forth Areas.— For the 

 critical determination of the following spiders, collected by me 

 a number of years ago on two fairly high hills in Perthshire, I 

 am indebted to Dr Randell Jackson, Chester, the author of the 

 two most recent contributions to our knowledge of the Spider-fauna 

 of the Scottish Highlands. 



1. From under stones on the very summit of Cru Ben (3250 

 feet), Tarmachans, near Killin, 20th August 1905: — Erigone 

 tiroleusis^ L. Koch, 2 (^ , i $ ; Hiiaira frigida, Thor., several ? ; 

 also Mitopus /Jiorio, F. (Phalangid), two. On Craig Cailliach, 

 another of the Tarmachans, Harpactes hoinbergii, Scop., i $ , and 

 some immature Argiopids, etc., were found. 



2. From Stuc-a-Chroin (3189 feet), near Callander, 17th 

 September 1906, under stones on the Forth side of the summit 

 ridge : — Erigone tiroknsis, L. Koch, 1,^,1 $ 5 Hiiaira frigida, 

 Thor., 2 $ ; Pa'cilonela globosa, AN'id. {Bathvphantes variegatus, 

 Bl.), 2 5 j Macrargus abnorniis, Bl., 1 ? ; Caledonia evansii, Cb., 

 I (^ ; also the Phalangids, Mitopus niorio, F., and Neinastoma 

 chrysomelas, Herbst. 



Erigone tirolensis was added to the British list by Ur Jackson 

 so recently as 191 3, he having discovered it on Ben Nevis in July 

 of that year. In 1914 he again found it on the same mountain, and 

 also on Cairn Toul and Ben Muich Dhui. Hiiaira frigida — under 

 the name of Tmeticiis fnontigena, L. Koch — has already been 

 recorded by me from Tay (Ben Vorlich) and Forth (Am Binnein) in 

 Ann. Scot. Nat. Hist., 1905, p. 120. — William Evans, Edinburgh,
