SYNOPSIS OF THE FAMILIES OF BRITISH 

 SPIDEKS. 



t TEEBITELAKLE. 



Spiders forming their nests in cylindrical holes in the earth > 

 the aperture usually closed by a distinct, hinged lid. (The only 

 British species, however, are an exception ; see p. 3.) 



Theraphosides. — Eyes 8. 



p. 1. Falces articulated horizontally with a vertical 



movement. 

 Spinners 4 or 6, those of the superior pair, 



long, strong and upturned. 

 Normal spiracular openings four in number 



widely separated, forming a large square 



figure, and all leading to Sac-Tracheoe. 

 Legs robust ; terminal tarsal claws 3. 

 Palpi (of the female) pediform, and used in 



locomotion . 

 Spiders mostly of large size, robust, hairy, and 



of sombre colouring. 



TUBITELAKLE. 



Spiders forming nests of a tubular kind, spun in crevices, 

 under stones, in angles of buildings, and such like situations. 

 At their outer extremity these domiciles are often expanded into 

 more or less diffuse sheets of web. 



t Tho seven groups, Territclar'ue, §c, into whioh the families of British 

 spiders are here divided, have some of them been noticed pp. n., xxiii. 

 Introduction. They represent tho old Latreillean families of spiders, and 

 aro based either on the different forms of web, or on the mode of pro- 

 gression. These groups are indicated here, although not of great value 

 from a scientific point of view, because they are both of interest and assist- 

 ance to the collector in determining tho primary systematic position of his 

 oaptures. Dr. Thorell indeed has raised these groups (though, it appears 

 to me, without sufficient reason) to tho rank of Suborders. (T. Thorell on 

 European spiders, p. 42).
