Another result of the recent investigations above referred 
to has been to show that the ZL. tenebricola of Cambridge’s 
“Spiders of Dorset” is not the Z. tenebricola of Wider, but 
must be restricted to the Z. tenwis of Blackwall. The latter 
name has, therefore, to be substituted for the other in our 
list. Mr Cambridge has specimens of the true L. tenebricola 
of Wider from “Scotland” (exact locality not known), so 
that it will probably be found in our district in time. All 
the specimens we have recently sent to the Messrs Cambridge 
have, however, been referred by them to Z. tenwzs (Bl.).

Spid. Dorset (in part); C. and E. List Spid. Edin., p. 578. 
Since the publication of our list, Mr Fred. O. P. Cambridge 
has examined a large number of specimens (including ours) 
of Tetragnathe from England, Scotland, and Ireland, and 
has found no less than four species besides the true Aranea 
(Tetragnatha) extensa, Linn. (the name hitherto applied to 
all British examples), represented. Those from the localities 
given in our paper he refers to 7’. solandrii, Scop. Specimens 
taken in May 1894 on a moor about two miles south of 
Callander he refers to 7’. extensa (L.), and this is the nearest 
locality from which we have as yet had it authenticated. 
III. ADDITIONAL LOCALITY-RECORDS, Evc. 
Drassus blackwallii, Thor.—This is one of the four species 
included in our list which we had not ourselves detected in 
the district. To the locality mentioned by Mr Cambridge 
(Arthur’s Seat), we are now, however, able to add another, 
namely, houses in Aberlady, where, in August 1896, we 
obtained an adult male (which Mr Cambridge has seen) and 
two females.
