I—INTRODUCTION AND LOCALITY RECORDS.” 
THE following paper contains an account of a short holiday in Scotland, 
which was spent for the most part in collecting spiders. I was only absent 
from home fifteen days, and was much hampered by wet and stormy weather. 
Nevertheless, I had considerable success, and believe that this was due 
chiefly to the carefully planned itinerary. In all thirteen species were 
added to the Scottish list. Eight of these were new to Britain, and two of 
these eight I am introducing as new species. The following are the names 
of these thirteen species :— 
Xysticus luctuosus Bl. Coryphceus mendicus L. Koch. 
Entelecara errata Camb. Erigone tirolensis L. Koch. 
Styloctetor morula Camb. Tiso zstivus L. Koch. 
Maro Falconerii Jackson. Theridion bellicosum E. Sim. 
Maso Brittenii Jackson. Robertus scoticus sp. nov. 
Clubiona subsultans Thor. Leptyphantes cacuminum sp. nov. 
Zilla Streemii Thor. 
Of these the first five are new to Scotland, the next six to Britain, and the 
last two, I believe, to Science. In all 130 species of Aranee, 6 of Opiliones, 
and 2 of Pseudo-scorpiones were obtained. I did not, however, go out of my 
way to look for common species. 
The following places were visited :—Aberlady links and sandhills, a day ; 
Trossachs, about three hours; Rannoch, about four days; Schiehallion, a day; 
Ben Nevis, rather over two days; Mallaig, a couple of hours; Crinan, a couple 
of hours. 
Of course in such an extended tour a great deal of time was spent in 
travelling. I must admit, too, that much was consumed in the admiration of 
scenery. The weather during the whole time I was at Rannoch was terrible. 
The chief moral of these results is that the Highlands of Scotland are 
almost virgin soil as far as Arachnids are concerned. Prof. Trail, Mr W. 
Evans, and the Rev. J. E. Hull have done good work, but far more in- 
vestigators are wanted. Half-a-dozen collectors in different parts of the 
Highlands would do wonders. Is it too much to expect that Edinburgh 
should produce them ?— 
On June 5th, Mr Wm. Evans kindly took me to Aberlady, the locality
