3 6 NEW AND RARE BRITISH SPIDERS. 



Legs rather short, strong, sub-equal, 4, i, 2, 3 and furnished 

 pretty thickly with strong bristly hairs. Those beneath the tibiae 

 of the first pair are almost spines, and form two longitudinal rows, 

 reminding one of the genus Maso, Sim. ; towards the posterior end 

 of the tibiae of the third and fourth pairs is a long nearly erect 

 slender spine ; tarsi much shorter than the metatarsi. 



I'\ilces strong, very convex in front, straight. A row of very 

 minute teeth on the front margin of the fang groove. 



Maxilla short, strong, obliquely truncate at the extremity on 

 the outer side, inner side straight. 



Labium more than double as broad at the base as it is high ; 

 at its apex the width is a little less than at its base. 



Sternum as broad as long, very convex, fore-margin hollow- 

 truncate ; posterior extremity slightly produced into a broad 

 truncate termination between the coxae of the fourth pair of legs. 



Abdomen short, oval. Spinners short, superior and inferior 

 pairs, apparently of equal length, and enclosed in a kind of 

 sunken cavity of a circular form. 



This genus is apparently allied both to Sintula and Maso, but 

 differs in various respects from both. 



Susarion neghctum, sp.n. 

 Adult female, length i line. 



Cephalothorax of a dull orange colour, the normal indentations 

 indicated by indistinct brown lines, and a radiating patch of the 

 same at the occiput. 



Legs and palpi of a clearer orange than the cephalothorax. 



Fakes similar in colour to the legs. 



Maxillae and labium suffused with brown. 



Sternum darkish yellow-brown. 



Abdomen dark brown tinged with yellowish, and furnished 

 thinly with coarse hairs. Genital aperture of very distinct and 

 characteristic form. 



A single example of the female was found among heather near 

 Bloxworth in 1882, and has remained unique to the present time. 

 It seems to me to belong to no genus as yet characterized,
