The body of the female is convex and of an oblong oval shape. 

 The margins of the cephalothorax are angular, but as well as the 

 surface devoid of tubercles or spines ; beneath the front margin 

 over the base of the falces are two blunt projecting processes. 

 The eye-eminence is small and smooth (fig. 7 b). The colour is 

 testaceous, very pale in young specimens, and becoming darker 

 with age ; the front and sides of the cephalothorax, the apex of 

 the abdomen, and an oblong quadrate spot on the dorsum of 

 the latter are dark brown ; the dorsal spot or band is spotted 

 with yellow. A brown or black circle surrounds the eyes. The 

 legs are dark brown in mature specimens, with the ends of the 

 femora and tibire mostly white ; when young the legs are pale. 

 The palpi are tinged with brown on the upper surface. 



The male differs from the female in being much smaller; in 

 having the body short and round (fig. 7 a) (whence the name 

 of the species) ; in being darker in colour (ferruginous when 

 adult) ; in being devoid of dorsal band, and other dark marks 

 on cephalothorax or abdomen. The legs are also much longer 

 and darker in colour ; the second pair of legs is twelve and a 

 half times the length of the body. 



This species is very abundant in woody places, where it may 

 almost always be seen in the summer, running rapidly over the 

 leaves and long grass : it is very frequently infested with the 

 parasitical red mite. 



Genus 5. Nemastoma, Koch. 



Body short and ovate ; cephalothorax and abdomen without 

 any distinct line of separation; eyes seated either upon an irre- 

 gular eminence near the anterior border of the cephalothorax, 

 or upon elevated scale-like projections. Body distinctly annu- 

 lated ; rings separated by an interval at the apex of the abdomen. 

 Palpi long and filiform. Falces horned in the males.
