A LIST OF SPIDERS COLLECTED IN " UPPER FORTH " 227 



a considerable share of attention, with the results embodied in 

 the following list. My investigations have been made mainly 

 around two centres, Callander and Aberfoyle, and for the 

 most part in the months of April, May, and September. A 

 few weeks' diligent search at other seasons of the year, 

 especially during late autumn and winter, when many of the 

 small TJieridiidce reach the adult state, would no doubt have 

 materially lengthened the catalogue of species, but hitherto 

 I have not been able to spare the necessary time for this. In 

 1861 the Rev. O. P. Cambridge spent a couple of days (3Oth 

 June and ist July) at the Trossachs collecting Spiders 

 (vide "Zoologist" for 1862, and "Entomologist" for 1877), 

 and obtained four species which as yet I have not found 

 in the district : these we have inserted in their proper 

 places. 



The present list contains 125 species, but future research 

 ought to well-nigh double the number ; for the district, with 

 its warm valleys, and hillsides clothed with heather, juniper, 

 oak copse, birch, bog myrtle, etc., has few superiors in Scot- 

 land. Of the 125 species here recorded, sixteen are not in 

 our Edinburgh District list (" Proc. Roy. Phys. Soc.," xii. 

 pp. 527-590, and xiii. pp. 308-315), while one Episinus 

 truncatus does not appear to have been previously detected 

 in Scotland. Taking our Edinburgh list, which now contains 

 1 80 species, 1 to represent " Lower Forth," we have thus a 

 total of 1 96 recorded for the whole of " Forth." To this 

 should perhaps be added about half a dozen species from 

 the north-east corner of Berwickshire recorded in Dr. 

 Hardy's lists, which we have not yet found within the water- 

 shed. 



I have again been fortunate in securing the co-operation 

 of my friend Mr. Carpenter of the Dublin Museum in the 

 most important part of the work, namely, the proper identifica- 

 tion of the specimens collected ; and we have jointly to thank 

 the Rev. O. P. Cambridge, F.R.S., for the continuation of 

 his assistance in cases of difficulty.]
