rounded, towards their extremity od the outer side with a long, 

 strong, black spino, forming a very largo, conspicuous double 

 coil, within which is a quantity of whitish mombrane. 



The abdomon is oval, and projects well over the baso of the 

 cephalo-thorax ; its colour is glossy black furnished thinly with 

 hairs. 



This spider is nearly allied to Walckcndera nudipalpis, Westr., 

 which it rosombles in general appoaranco and colours, but it may 

 be at once distinguished by a different formation of tho palpi, 

 especially tho form of the outer apophysis of the radial joint, 

 which in W. nudipalpis is slenderer, more prominent, and ends 

 with a small sharp-curved claw, and has, noar its extremity in 

 front, a small somewhat tubercular prominence. Tho radial 

 joint itself is also shorter and stronger, and the surface of the 

 cephalo-thorax is more coarsely striatod or sculptured. 



I met with an adult nialo among moss in Berowood on the 6th 

 of April, 1880 ; the only previous example known having been 

 found by Mr. Blackwall many years ago in North "Wales ; and 

 on tho 1st of May, 1880, I found an adult female among moss in 

 a wood at Bloxworth. This sox resembles the male in colours 

 and general characters ; it is also very like the female of W. 

 nudipalpis, but is larger and differs in the form of the genital 

 aperture.

The cephalo-thorax is of a deep brown-black hue ; tho caput 

 elevated and prominent, but with no distinct eminence ; its 

 summit is truncated and slopes forwards, and the slope of the 

 occipital region is rather abrupt. The eyes are grouped in four 

 pairs round the summit of the caput, but there is no indenta- 

 tion behind those of the lateral pairs. The legs are moderate 

 in longth and strength, 4.1.2.3., and their co^ur is yellow,
