ARACHNIDA. 

 BY WILLIAM EVANS, F.RS.E. 



OKDER ARANEIDEA. 



ARRANGEMENT AND NOMENCLATURE : Eev. O. P. Cambridge's List of 

 British and Irish Spiders, 1900. 



"Clyde" on account of its position and the diversity of country will, when 

 thoroughly investigated, probably be found to occupy a high place among 

 the ' drainage areas ' of Scotland. This should act as a stimulus to resident 

 naturalists to take up the work begun by the late Morris Young and H. C. 

 Young. Their records have been of the greatest service in compiling this 

 list. Help has also been received from many local naturalists to all of whom 

 I here tender my best thanks. I have personally only * sampled ' the Clyde 

 spiders at various points but my captures include 5 new to the Scottish list, 

 two (Tapinocyba pollens and Cornicularia Jcarpinskii) being first records for 

 Britain. 



The number of species in this list is 201 out of 290 recorded from Scot- 

 land and as against 215 in the adjoining "Forth" area. A good many are 

 rarities, but space does not allow me to particularise. 



Reliability in the identification being of the first importance, it is satis- 

 factory that the high authority of the Eev. O. Pickard-Cambridge, F.R.S., 

 can be cited for nearly every species on the list. My personal obligations to 

 him in this matter are very great, and he has my hearty acknowledgment 

 and thanks. I have also to thank Mr. G. H. Carpenter, B.Sc., for verifying 

 the determinations of some of my Arran specimens.
