Spiders collected in Neighbourhood of Edinburgh. 573 
has been confirmed by Mr Cambridge. The species is recorded 
by M. Simon from Martigues, near the mouth of the Rhone, 
in France; Arbucias, Catalonia, in Spain; and Alexandria, in 
Egypt. The occurrence of such a characteristic Mediterranean 
species on the shores of the Firth of Forth, opens up some 
interesting problems in animal distribution. 
Plesiocrerus permixtus (Cb.). 
Walckenaéra permixta, Cambr. Spid. Dorset. 
In swampy places, widely distributed but not very com- 
mon. We have as yet taken it only in late summer and 
autumn, which is the season when it occurs in France, 
according to M. Simon, but Mr Cambridge has found it in 
Dorset in May.

Plesiocrerus alpinus (Cb.). 
This species, of which we have taken specimens in several 
localities around Edinburgh, and which is recorded now for 
the first time as British, appears to be a characteristically 
mountain form. It was discovered in 1865 by Rev. O. P. 
Cambridge, at Bruck-am-Muir, in the Styrian Alps, and has 
also been taken in the Tyrolese Alps, at an elevation of 6000 
feet. Its only other known locality is in the Maritime Alps 
1 While this paper is passing through the press, Rev. O. P. Cambridge 
records this species in Proc. Dorset Nat, Hist. and Ant. Field Club, vol. xiv.
