Second Contribution to Spider Fauna of Scotland. 179 
On June 6th, Ben Nevis was ascended. There was about eight feet of 
snow on the summit, which was enveloped in clouds and bitterly cold. 
Specimens were taken chiefly from three areas. 
About 2000-2200 feet :— 
Crypheeca silvicola C.L.K. 
Theridion bellicosum Sim. Both sexes. Males much rarer 
than females. 
Robertus lividus Bl. 
Walckenaéra capito Westr. One female. 
Micryphantes sublimis Camb. Two males. 
Leptyphantes Zimmermannii Bertk. 
. Whymperii F. Camb. One female. 
Obisium muscorum Leach. 
This locality was the scree bed above the half-way house. 
Between 3000 and 3500 feet the following occurred :— 
Styloctetor morula Camb. Two females. 
Entelecara errata Camb. Both sexes. 
Erigone tirolensis L. Koch. Both sexes. 
Coryphceus mendicus L. Koch. Two females. 
Hilaira frigida Thor. Females only. 
Leptyphantes cacuminum Jackson. One female. 
Nemastoma chrysomelas Herbst. One male. 
Over 4000 feet :— 
Entelecara errata Camb. 
Coryphceus mendicus L. Koch. 
Hilaira frigida Thor. Not rare. 
Macrargus adipatus L. Koch. One female. 
Leptyphantes cacuminum Jackson. One female. 
3 Whymperii F. Camb. Females. 
Linyphia pusilla Sund. One male. 
a clathrata Sund. One male. 
The occurrence of the two species of Linyphia is very unusual in such a 
situation. No doubt each had reached the place on a chance aeronautic 
excursion. Both were found under stones, the specimen of clathrata in a 
very snowy neighbourhood not far from the summit. Spiders of all species 
were much rarer than in 1913. I was on Ben Nevis in that year a week 
later, but there was far more snow about then than in the present year.
