NOTES ON BRITISH SPIDERS. 17 



other, the interval between them is less than half a- diameter, 

 that between the hind-centrals is equal to a diameter, and 

 distinctly less than that between them and the hind-laterals. The 

 central quadrangle is longer than broad, and narrowest in front. 

 Those of each lateral pair are seated a little obliquely on a 

 tubercle, and the fore-laterals are separated from the fore-centrals 

 by slightly less than the diameter of the latter. 



Legs moderately strong, rather short, not greatly unequal in 

 length 4, i, 2, 3, furnished with hairs and very slender bristles, a 

 few erect ones of the latter are on the tibiae. Colour, yellow- 

 brown with a slight red-brown tinge. The innerside of the 

 femora of the first and second pairs are furnished with numerous 

 distinct parallel transverse striae, whose edges appear to be sharp 

 and a little raised. 



Palpi short, cubital very short, curved, slightly clavate ; radial a 

 very little longer than the cubital, and stronger, rather broadly 

 and roundly produced in front, the fore-margin on the upper side 

 has a slight notch near the outer side, digital joint equal in 

 length to the cubital and radial together, oval, obtuse at the fore- 

 extremity, and with a conical lobe on the outer side. Palpal 

 organs rather prominent and complex. A curved corneous 

 blade-like process is situated at their base on the outer side just 

 beneath the outer margin of the radial joint, and another runs 

 from near their base on the innerside to their anterior extremity, 

 ending in a black tapering curved spine, in front of which, and 

 connected with another process, there appears to be another more 

 slender black filiform spine. The outerside of the humeral joint 

 is furnished, like the femora of the first pair of legs, with numerous 

 transverse striae on the inner sides. 



Fakes strong, divergent, with a patch of granulosities in front, 

 and a close set row of teeth on the inner margin at the extremity. 

 The outer margin is furnished with numerous transverse striae or 

 sharp-edged ridges, in connection with which possibly those on 

 the femora of the first pair of legs and on the humeral joints of 

 the palpi act as a stridulating apparatus. Colour of falces 

 yellowish brown tinged with blackish.
