of Meta tegmentata. It is not an unfrequont spider at Bloxworth 

 and other localities in Dorsetshire, in such situations as those 

 ahove noted, and indeed it appears to be generally distributed 

 throughout Great Britain. 



GENUS TETEA.GNATHA, Lair. 



The eephalo-thorax is of an oblong-oval form, but wider in the 

 middle than elsewhere, and somewhat truncated at bothonds. The 

 lateral marginal constrictions at the caput are slight, the whole 

 is rather flattened, and the caput is but slightly raised above the 

 thorax. 



The eyes aro small, and in two transverse rows, occupying 

 nearly the whole width of the caput. Four form very nearly a 

 square in tho centre, and those of each lateral pair are distinctly, 

 and often widely, separated from each other. 



The legs are very long, slender, and armed with rather fino 

 spines; their relative length is 1.4.2.3, those of the first pair 

 being considerably the longest. 



The maxilla are long, straight, and greatly enlarged on the 

 outer side at their extremities, giving them the appearance of 

 divergence. 



The labium is of a somowhat semicircular or quadrate form, 

 rounded at the apex, but broadest at the base. 



The falces are long and very divergent — especially in the males, 

 and diversely armed with a very long fang, numerous teeth and 

 other denticular processes. 



The palpi of the male have tho digital joint split (as it were) 

 into two elongate portions ; the palpal organs are very simple, 

 consisting of a basal bulb more or less prolongod at the anterior 

 extremity, which often has one or more fine spines. 



The abdomen is of a narrow, elongate or cylindrical form. 



One species only is yet known in Britain, and that is an 

 abundant and generally distributed one in Dorsetshire.
