The eyes are very small, seated on small black spots, those 

 of the fore central and two lateral pairs form a transverse 

 curved row, each fore central eye being separated from the 

 fore lateral next to it by an eye's diameter. The eyes of the 

 hind central pair are separated by rather more than a dia- 

 meter's interval, and, with those of the fore central pair (which 

 are the smallest and nearly contiguous to each other) , form a 

 long narrow trapezoid, whose length is about double its width 

 at the upper (or hinder) part. 



The^j>aZ^«' are similar in colour to the legs, and ^hort ; the 

 radial is shorter but stronger than the cubital joint, and has 

 its fore extremity on the upperside a little prominent, with 

 two very small points at its most prominent part, one of 

 these points (the largest) being obtuse and black, and the 

 other acute and pale. The digital joint is small, oval ; the 

 palpal organs are simple, not much developed, and have a 

 small, fine, black, curved, filiform spine at their extremity. 



The /a/ces are rather weak, straight, and slightly inclined 

 backwards towards the labium. 



The legs are short, tolerably strong ; the tibife only a little 

 less stiong than the femora ; they are furnished with coarsish 

 hairs and a few erect bristles. 



The sternum is convexly prominent, margined narrowly 

 with black, and strongly suff"used with dusky brown. It is 

 of a short heart-shape or somewhat subtriangular. 



The abdomen is oval, and projects considerably over the 

 base of the thorax. 



An adult and an immature male of this spider (which in 

 colours nearly resembles Walckcnaera ludicra^ Cambr.) were 

 found among heather on Bloxworth Heath, on the 8th and 

 29th of April, 1881.

Three adult examples (two females and one male) were 

 found on the 24th of July, 1881, among grass in paths in a 

 wood at Bloxworth_, where I had found the typical examples 

 in the same mouth of the previous year. It is perhaps one of 

 the most striking species, from the strong contrast of its colours, 

 among those found in Great Britain.
