142 ON NEW AND RARE BRITISH ARACHNIDA. 



it. The fore-central pair are the smallest of the eight, and 

 separated from each other by half a diameter's interval. Fore- 

 laterals largest ; each lateral pair on a strong tubercle. 



Legs rather long, slender, 4, 1,2,3. Colour, dull yellow-brown. 



Palpi moderate in length, slender, similar in colour to the legs ; 

 radial joint about equal in length to the cubital, but stronger and 

 broader at its fore extremity, where there appears to be a pointed 

 apophysis at its fore extremity on the outer side and a more 

 obtuse one on its inner side ; from another point of view the 

 outer apophysis appears to be of a somewhat bifid form. The 

 digital joint is rather small, with a prominent lobe on its outer 

 side, and the palpal organs are rather complex. 



Falces moderately strong ; roundly prominent at their base in 

 front ; compressed near their extremity and with a strong 

 prominent sharp tooth towards their extremity in front ; their 

 colour is like that of the caput. 



Maxillae, labium, and sternum similar in colour to the caput, 

 the sternum perhaps darkest. 



Abdomen bright red with a broadish terminal band of jet black 

 surrounding the spinners, and thinly furnished with short fine 

 hairs. 



The female resembles the male in colours and general 

 appearance, but is larger and wants the strong tooth on the fore 

 side of the falces. The genital aperture is of characteristic 

 form, but not of large size. 



Both sexes have been received from Mr. H. Donisthorpe, by 

 whom they were found in heaps of vegetable refuse at Enfield, 

 Middlesex, and in heaps of old bones at Queensborough, in 

 Kent. It is one of the most distinct and striking species I have 

 seen.
