The colour of the cephalo-thorax is brownish-black, that of the 

 logs red-brown, and the abdomen black. 



The radial joint of the male palpus is stronger than the cubital, 

 and has its fore extremity, on the upper side, greatly produced 

 into a long, curved, tapering apophysis, whose point is directed 

 outwards in front of the digital joint; this joint is not very 

 large. The palpal organs are prominent and complex; they 

 do not contain any very remarkable processes, but have a short, 

 pointed, black, curved, prominent spine at their extremity. 



This is not a rare spider. I have found it, frequently, running 

 in sunshine on bright spring and early summer mornings, on 

 iron railings at Bloxworth, and it has also been found in Lan- 

 cashire, North Wales, and Scotland. The female resembles the 

 male, but wants the elevation of the caput and is slightly larger.

Theridion pusillum, Wid., Zool. Misc. Arach. (Mus. Senck.),

The male of this minute spider measures no more than l-22nd 

 of an inch in length. 



The caput is moderately elevated, bearing considerable resem- 

 blance to that of Walckenaera pieina, Blackw., though rather less 

 in height, and the front slope is less steep, forming in profile a 

 very obtuse angle with tho slopo of the clypeus, which is nearly 

 vertical ; each side of tho elevation, above and behind the lateral 

 pairs of eyes, is broadly and deeply indented, and the eyes of 

 the hind-central pair are seated widely apart at the fore part of 

 its summit. 



The colour of the cephalo-thorax is yellowish-brown, that of 

 the legs and palpi yellow-brown tinged with red, and the abdomen 

 is dark sooty brown. 



The palpi are short; the radial joint is stronger than the 

 cubital, and is produced at its fore extremity, above and rather 

 on the inner side, into a strong apophysis which curves outwwda
