Amaurobius pilosus, nov. sp. (PI. XIIL, Fig. 1). 



Cephalothorax, black-brown, with grey hairs. Mandibles, 

 black-brown in front, with brown hair, underneath paler yellow- 

 brown and smooth. Fangs, the basal half bright yellow-brown, 

 remainder paler. Lip and maxillae, yellowish grey, paler at 

 edges, with brown upstanding hair. Sternum, black-brown, 

 yellowish grey hair. Legs and palpi, darkish brown on femoral 

 joint, paling to yellowish brown on others, white to greyish 

 yellow hair. Patella, tibia and metatarsus ringed with dark 

 grey. Abdomen, black-brown, with long grey hair above, no 

 pattern, underneath a median field of dark brown hair edged 

 with white and two parallel longitudinal lines of white hair 

 reaching the whole length near median line, spinnerets and 

 cribellum yellowish grey. 



The Cephalothorax is broad and convex on cephalic part ; 

 equally high, rather long, and rounded at sides on thoracic part ; 

 shorter than patella cum tibia lY. ; rather steeply sloping at 

 sides and rear ; a shallow median furrow at top of rear slope. 



The front row of Eyes is straight, middle eyes round, side eyes 

 oval, their long diameter the same as the middle and that 

 distance away from them ; the same also is the breadth of the 

 clypeus. The rear row is procurved, all round, diameter equals 

 two-thirds of front middle, two and a half diameters apart. Side 

 eyes on a protuberance with front side, their diameter apart. 



The Mandibles are knee-formed at base, conical, longer than 

 patella I., thicker than femur I., and thickly covered with hair. 

 The fangs are short, thick at base, and well curved. On the 

 inner edge of false sheath, which is very sloping, are two small 

 teeth, on outer edge four, of which the third is the largest. 



The Maxillae are straight at sides, upright, and slightly 

 rounded on front edge. The Lip is more than half the length of 

 these, rounded at sides, straight in front and very slightly 

 notched. There are fine upstanding hairs on both. 



The Sternum is pear shaped, raised at edges, but flat on top. 

 It ends in a long fine point, which reaches between the separated 

 rear coxae. It is thickly covered with long hair, curling towards 

 the centre, and this is intermixed with short, flat, white hairs.
