ON SOME NEW AND RARE BRITISH ARACHNIDA. 85 



Bathyphantes spretus, sp. n. Figs. 4-7. 



Adult female, length slightly over i line. 



Cephalothorax, uniform dark yellow-brown ; ocular area 

 slightly prominent ; lateral marginal impressions at the caput 

 slight ; height of clypeus (which is a little impressed beneath 

 the fore-central eyes) about equal to half that of the facial space. 



Eyes on blackish spots in two transverse rows, reaching across 

 the whole width of the caput ; posterior row very nearly straight, 

 both rows, very slightly and about equally curved, in opposite 

 directions ; hind-central pair larger than the hind-laterals, but 

 nearer together than to these ; lateral pairs each on a strong 

 tubercular eminence ; fore-centrals on a slight tubercle, and 

 separated by half a diameter's interval. 



Legs long, moderately strong, of a dull pale yellowish hue, 

 i, 2, 4, 3, furnished thinly with hairs and spines on the tibiae ; 

 none on the metatarsi of the first and second pairs. 



Fakes long, tapering, and a little divergent towards their 

 extremity ; colour yellowish-brown. 



Maxillae and labium similar in colour to the falces. 



Sternum dark brown. 



Abdomen oval; upper side pale dull yellowish-brown, darker 

 on the sides and underneath, with traces of a longitudinal 

 central darker stripe, and marked on the hinder part with 

 a series of several transverse pale angular markings or chevrons. 

 Probably in fresh specimens the colour and markings would be 

 much better defined. 



The genital process and aperture are large, and of a very 

 distinct and characteristic form. 



A single example was received from Mr. Freston, by whom it 

 was found at Watton, in Norfolk.
