Eev. F. O. Pickard-Cambridge on British Spiders. 27 



Clypeus very narrow, equal to the diameter of central 

 anterior eyes, its margin set with six or seven curving bristles. 



Falces broad, stout, convex, conical, clothed with curving 

 black hairs. Inner margin set with numerous curving hairs ; 

 upper margin of fang-groove bearing three teeth, lower 

 margin with two. 



Palpus set with stout black spines, bearing at apex a dark 

 simple tarsal claw. 



Maxillce twice as long as labium, broad, parallel-sided, 

 very slightly enlarged and obtusely truncate at apex ; fringed 

 with curving bristles and bearing a denser tuft of finer hairs 

 on inner anterior margin and a small black tuft at apex. 



Labium oval-quadrate, truncate at apex ; fringed with 

 dark bristles. 



Sternum slightly longer than broad, convex, clothed with

between the coxte ot posterior pair of legs. 



Legs 4, 1, 2, 3, fairly long, clothed with dark hairs. An- 

 terior pairs less spinose. 



Femora i. with 2 dorsal, 1 anterior-apical, and 1 dorsal- 

 apical spine. 



Femora ii. with 3 dorsal spines. 



Femora iii. with 3 dorsal and 3 apical spines. 



Femora iv. with 2 dorsal and 3 apical spines. 



Patella of all four pairs with a single basal and apical 

 spine. 



Tibice i. with two pairs of stout spines beneath. Tibiae ii. 

 with two spines 1 — 1 beneath. 



Profarsi^ i. and ii. with two pairs of spines beneath. 

 Tibiae and protarsi iii. and iv. with numerous spines on all 

 sides. 



Tarsal claws two. Onychium bearing a few upturned 

 bristles, but no claw-tuft. 



Abdomen oval-elongate, compressed, parallel-sided, thinly 

 clothed with fine dark hairs ; dull brown, with a narrow, pale 

 yellow, central dorsal band extending from the base nearly to 

 the spinners, flanked by a pale irregular band, extending 

 from base and converging to the spinners. Ventral area pale 

 yellow. Spinners short, cylindrical, situated in a quadrangle. 

 Superiors slightly longer and further apart ; inferiors set one 

 diameter apart at base, having in front of them a lunulate 



* Mr. R. I. Pocock, of the Natural History Museum, South Kensing- 

 ton, has suggested protursus instead of metatarsus ; and, seeing that we 

 enumerate the joints from the basal end and arrive at the sixth joint 

 before the seventh (tarsus), the term jvotajsus seems to describe the 

 joint and its position better than the old term jnetatarsus.
