220 Mr. C. Warburton on Spiders Jro7n Madeira. 



Cephahtliorax and legs a rich glossy yellow. An indistinct 

 paler streak down the middle of the cephalothorax. Ocular 

 area prominent and of a dead whitish colour. Lateral ante- 

 rior eyes largest. The anterior row distinctly convex towards 

 the front and shorter than the posterior row, which is very 

 slightly convex, the eyes being nearly equal in size and the 

 medians somewhat nearer together than each is to the lateral. 



Abdomen probably of a vivid green in life, showing when 

 magnified a fine black reticulation. There are numerous 

 short spines on black prominences under the tibiae and meta- 

 tarsi of the first and second pairs of legs. 



I have named this spider after its discoverer, Mr. J. W. 

 Clark, a single female being contained in his collection.
