262 Natural History of Middleton-in-Teesdale. 



halt at High Force, several species being obtained there, 

 amongst them being Harpactes hombergii Scop., Cryphceca 

 silvicola C. L. Koch, Walckenaera nudipalis Westr., Nesticus 

 .cellulanus Clerck, Era thoracica Wid., Neon reticulatus Bl., 

 and the rarer or more local Leptyphantes obscuris Bl., and 

 X. flavipes Bl. Beyond the fall beneath a stone at the foot of 

 the cliffs Mr. Winter found two of the beautiful stalked balloon- 

 shaped egg cocoons, and a young indeterminable example of 

 a species of Agroeca. A little farther on, but still on the 

 Durham side of the river, at a great bend covered with thick 

 low-lying tufts of ling, grass and moss, Mr. Falconer shook out 

 one male Maro falconerii Camb. and one female Clubiona 

 diversa Camb. The former previously found only in Cheshire 

 and West Yorkshire is new to Durham county, its limit of 

 range being thus greatly extended northwards? On crossing 

 Cronkley Bridge into Yorkshire, the distance still to be traversed 

 was so great, and the time so short, that very little collecting 

 was possible, though Mr. Winter managed to secure a fine 

 female Tarentula andrenivora Walck, with her egg-sac, between 

 White Force and Maize Beck. On the second day the neigh- 

 bourhood of Winch Bridge yielded one male Troxochrus 

 Memalis Bl., and a number of common species. On the third 

 day the south bank of the Tees as far as its junction with the 

 Lune was investigated, the return journey being made along 

 the left bank of the tributary. Here Leptyphantes tenebricola 

 Wid., a spider for which there are few other Yorkshire or north 

 of England records, occurred, and dozens of Lycosids sped 

 swiftly over the grass in the bright sunshine, attempts to 

 catch them affording excellent sport. Later examination 

 showed that no less than five species were represented. For 

 Lycosa agricola Thor. there is but one other Yorkshire record, 

 (Lower Teesdale). On the fourth day an hour was spent in the 

 woods at Barnard Castle, Leptyphantes tenebricola Wid. being 

 again met with. Altogether seventy species of true spiders, 

 five of harvestmen and one pseudoscorpion were noted. 



In the following complete list, the initial ' W ' denotes that 

 the species was found by Mr. Winter only ; ' F ' by Mr. Falconer 

 only ; and those uninitialled, by both ; the species not recorded 

 for Durham in Rev. J. E. Hull's ' Catalogue of the Spiders of 

 Northumberland and Durham, are distinguished by an asterisk, 

 though it is probable that, as other naturalists have been more 

 recently at work, who have not yet, however, published their
