ON NEW AND RARE BRITISH ARACHNIDA. 65 



little produced and truncated. The palpal organs are prominent 

 and well developed ; at their fore extremity is a strong black 

 circularly-curved spine, and at their base on the outer side is a 

 strong curved corneous process (paracymbium). 



Fakes long, moderately strong, straight, and of a dark 

 yellowish-brown colour. 



Maxilla and labium like the falces in colour. 



Sternum as broad as long, heart-shaped, broadly and obtusely 

 pointed behind, between the coxae of the fourth pair of legs. 



Abdomen short, oval, jet black, very shiny, and clothed with 

 hairs. 



The female resembles the male in general character and 

 colours. The form of the genital aperture is characteristic, but 

 much resembles that of Gongylidium retusum, Westr. 



Both sexes were found at St. Leonard's-on-Sea by Mr. Ruskin 

 Butterfield under the debris of grass and herbage, but nearly all 

 were immature. 



Styloetetor uhcinus, sp. n. PL A, Figs. 22, 23, 24, 25. 



Adult male, length i line. 



Cephalothorax oval, narrowest in front, rounded both in front 

 and behind ; lateral marginal impressions at caput obsolete ; 

 height of clypeus exceeds half that of the facial space, and 

 projects a little forwards to its lower margin. From the middle 

 of the upper part of the clypeus and from the ocular area spring 

 some upturned coarse bristly hairs. Upper convexity of cephalo- 

 thorax even, only a very slight depression in profile at the 

 junction of caput and thorax. Colour dull greenish-yellow 

 black-brown. The normal grooves and indentations indicated 

 by obscure darker lines and irregular markings. 



Eyes sub-equal ; fore-central pair much the smallest. The 

 width of the ocular area is nearly about double its length from 

 back to front ; posterior row of eyes curved, the convexity of the 

 curve directed backwards, the interval between the hind-centrals 

 rather more than an eye's diameter, and distinctly greater than
