leaves in -woods, and among moss and heather at Bloxworth ( 

 and Warm well. I have also received it from Mr. 0. "W. Dale, 

 of Glanvilles Wootton ; and it occurs more abundantly under 

 stones, among moss and short herbage in woods and on wastes 

 in the North, and other parts, of England, as well as in Scotland, 

 and Wales. 



GENUS PACHYGNATHA, Smd. 



Cephalo-thorax large and of almost equal convexity throughout. 



Eyes in two nearly straight transverse rows, forming a central 

 group of four in a small square, with a lateral pair placed 

 slightly obliquely at some distance on each side. 



Fakes long, vory powerful, and divergent. 



Maxillae long, rather broadest, and obliquely truncated on the 

 outer side, at their extremities, and inclined towards the labium. 



Labium large, of a sub-triangular form, with the apex some- 

 times rounded. 



Legs rather long, slender, and entirely devoid of spines. Their 

 relative length is 1.2.4.3. 



Palpi of the males have the palpal organs of a peculiar and 

 very uniformly similar structure, consisting of a large, more or 

 loss globular, corneous lobe with a diversely formed process 

 issuing from its fore part. In this, as well as in the narrow, 

 irregular form of the digital joint, there is a marked similarity 

 to spiders of the Epeirid genus Tetragnatha, Linn. 



This is a small group of brightly-coloured, and prettily marked 

 spiders, some of them ornamented with silvery hues. 



Their snare and mode of life are like those of Theridion. 

 They may be easily distinguished from Neriene and Walchena'era 

 by their gayer colouring ; from Theridion by the second pair of 

 legs being longer than the fourth ; and from the numerous species 

 of Linyphia by the absence of spines on the legs ; while their 

 form of snare separates them at once from the Family Epeirides, 

 to which last, however, they bear several strong structural 

 marks of affinity.
