THE SPIDERS OF THE TYNE VALLEY. 343 



The chief subalpine forms in the list are Caledonia Evansii 

 (Camb.), Tmeticus prudens (Csivah.), Tmeticus arcamis (Ca.mh.), 

 Microtieta stiblimis (Camb.), and Bolyphantes alticeps (Sund.). 



Lastly a few spiders here recorded are chiefly of southern 

 habit. Although several of them extend into Scotland, they 

 all have their British headquarters in the South of England. 

 Such are Xystiats pint (Hahn.), Xysticus lanio (C. L. K.), 

 Amanrobitis ferox (Walck.), Gongylidiuvi graminicolum (Sund.), 

 Enidia cormita (Bl.), Cyclosa C07iica (Pall.), and Cercidia 

 protTiinens (Westr.). 



Finally I have to thank those who have so kindly assisted 

 me in my pleasant observations on the Tynedale spiders. 

 The Rev. O. P. Cambridge, F.R.S., has seen and identified all 

 the spiders which I had not taken before in other localities. 

 He has also verified my identification of nearly all the other 

 species. The only forms I have not sent to him are the very 

 common ones. He has at all times been ready to assist me 

 with his advice, and with specimens from his unrivalled 

 collection. I have followed his nomenclature of genera and 

 species almost exclusively, but in the case of the arrangement 

 of the minute spiders have adopted M. Simon's family 

 Argiopidae with its subdivisions. The Rev. J. E. Hull, the 

 author of the " Catalogue of the Spiders of Northumberland 

 and Durham," has also been very kind in directing me to 

 certain localities, as well as in looking up many Continental 

 references in works to which I have not had access. Mr. 

 Falconer, of Huddersfield, Mr. F. P. Smith, of Islington, and 

 Mr. J. C. Varty-Smith, of Penrith, have all assisted me in 

 sending MS. lists of the spiders of their respective districts. 

 Mr. Falconer has also sent me many rare, and several new 

 Yorkshire spiders for comparison with Northumbrian examples, 

 and Mr, Bagnall is now sending me numerous Arachnids from 

 Winlaton-on-Tyne. As regards other local records I may 

 here say that my own notebooks have been extremely useful, 

 the Glamorgan and Manx notices being entirely, and the 

 Cumberland, Lancashire, and Staffordshire records partly 

 taken from their pages. I must also express my thanks to
