Spideo's a7}d Arachnids from the Edmhvrgh District. 173 



examples were found on rushes in a damp hollow on the 

 Pentland Hills, near Bavelaw Castle. During the same 

 month a few more were beaten out of heather in two 

 other localities on the Pentlands, namely, at Loganlee and 

 Craigenterrie. Occurs also on the Ochils above Milnathort. 



ALTERATIONS IN NAMES.

Dysdera ruhkunda, Blackwall's Spid. Gt. Brit, and Irel. 



Dysdera camhridgu, Carpenter and Evans' List Spid. Edin., p. 535. 



There can now be little or no doubt that the two $ Bysderce, 

 somewhat doubtfully recorded in our list as B. cambridgii, 

 Thor., and another since obtained in a house at North Berwick, 

 in August 1897, belong to the other British form, I), crocota, 

 C. L. K. We have been led to reconsider our former decision 

 by the discovery of a colony of the latter species, from which 

 both sexes were got, at Eyemouth, on the coast of Berwick- 

 shire, in September 1895 (Evans, Proc. Beriv. Nat. Cluh, xv. 

 p. 118), thus giving to it a much more northern range in 

 Britain than the other. The three specimens referred to 

 have, as the Eev. 0. P. Cambridge, to whom they have been 

 submitted, points out, on the upper side of the posterior 

 extremity of the femora of the fourth pair of legs, the one or 

 two small spines which are said to be almost always present 

 in crocota, but never in camhridgii. The latter name must 

 therefore be deleted from our list and the former substituted.

Mr Cambridge informs us that, after a careful comparsion 

 of the types, he has satisfied himself that our Scotch spider, 

 identified for us and described by him (loc. cit.) as Typhocrestus 

 digitatus, is not the same as his Continental spider of that 

 name, but is identical with his T. dorsuosus. The two forms 

 are evidently very closely related, and may not, after all, be
