common, most of the records being based on one or two examples chiefly 
females, 
Philodromus emarginatus, Lycosa prativaga, and Dictyna pusilla, are 
generally regarded in Britain as southern forms. Perhaps the chief feature 
was the abundance of Dictyna pusilla and Leptyphantes expunctus. I was 
surprised at my failure to get the Rannoch animals Clubiona subsultans Thor., 
Zilla Stremii Thor., and Robertus scoticus Jackson. I worked specially for 
these, and their absence from my list is thus the more noteworthy.

I have so named the species taken on the Cairngorm mountains and 
recorded above. I think this is correct, but no direct comparison of specimens 
with the types hasbeen made. After the present continental war is concluded 
this will have to be done. 
Mr Simon’s original figures, in the Avachnides de France, do not show the 
lamella characteristica of the male, which is absolutely necessary for the . 
diagnosis of these species. Dr de Lessert however figures this, and though 
his figure was apparently done under smaller magnification than mine, I 
believe the species to be identical. 
The male of this species taken by me is 1°75 mm. in total length. Its 
general facies is that of a very dark example of JZ sublimis Camb., or 
M. rurestris O.L.K. The absence of the curved process at the inner side of 
the base of the palpal tarsus easily distinguishes it from the former, and 
the shape of the lamella characteristica from either (see Fig. 2). Eyes 
as in the female. 
The females vary in length from 1°8 to 21 mm. They are of a dark 
brown, usually nearly black, colour, The legs are all dark brown. Palpi dark 
brown, the last two joints darkest. 
The vulva is extremely like that of JZ rwrestris C.L.K., and M. sublimis 
Camb., but darker than either. In shape it more closely resembles the former 
species, but is often rather broader and in fact somewhat intermediate between 
the two. 
The falcal armature and chatotaxy are typical of Micryphantes, and the
