Mr. R. H. Meade on the British species of Phalangiidse. 411 



with short spines. The ocular crests are each armed with four 

 long blunt teeth, the two middle or upper of which are longer 

 than the others, and the second from the front the longest of all. 

 The palpi are of moderate length ; the second joint is spinous 

 on its under surface, and the third and fourth are furnished 

 with projecting hairy processes at their extremities ; the fourth 

 has also two or three teeth on its under surface. The legs are 

 short, particularly the first and third pairs, which are much 

 abbreviated, particularly the former; the second pair is much 

 longer than the others. 



The predominating colour of this species is dull pale yellow, 

 which is mottled or variegated with white and reddish brown. 

 The spiracles on the external angles of the cephalothorax are 

 surrounded by a dark or black spot ; there is no distinct dorsal 

 band, but two rows of reddish-brown spots extend across the 

 thorax and abdomen, enclosing a longitudinal space betweeu 

 them, which is wide and triangular on the thorax, becomes con- 

 tracted at the base of the abdomen, and then dilates posteriorly 

 into an oval form. The legs and palpi are faintly annulated 

 with pale reddish-brown marks. 



The sexes of this pretty and well-marked little species are not 

 known ; the only specimen that I have seen, and which appeared 

 to be a male, was transmitted to me by Mr. Blackwall, and cap- 

 tured by that eminent arachnologist in North Wales. 



Genus 4. Leiohunm, Koch. 



Legs particularly long and slender. Body rather short and 

 round, especially in the males ; cephalothorax without tubercles 

 or spines ; eye-eminence small and quite smooth, being destitute 

 of crest j palpi rather short and slender, and without projecting 

 processes or angles.
