Trapdoor Spiders from Australia. Ill 



separated, the middle pair large, conspicuous, and lodged in 

 a transverse depression of the integument ; the posterior pair 

 closer together than the others, smaller than the median but 

 more conspicuous than the anterior ; the integument coriaceous, 

 longitudinally grooved in front, transversely behind and 

 below, scantily hairy ; the upper surface of the abdomen 

 armed with short backwardly directed spines, elevated on 

 distinct grauuliform tubercles. 



Spinners. Two pairs, the anterior short, conical, the poste- 

 rior also conical; the apical segment minute, the second 

 shorter than the basal. 



Palpi. ^1 axilla longer than wide, furnished below with 

 setge, intermixed with short setiform spinules, the base armed 

 internally with a cluster of the thick normal spiniform tubercles; 

 surface between the fringe and the suture bristly ; trochanter, 

 femur, and patella bristly below ; the tibia also bristly, about 

 four of the bristles on each side stout and spiniform ; tarsus 

 about as long as the tibia, somewhat thickly scopulate on 

 each side, nearly naked below, armed with two pairs of basal 

 spines, apically with about five shorter spines in the middle ; 

 claw armed with two basal teeth, the lower long and bifid. 



Legs. First and second pair with tarsi and protarsi scopu- 

 late externally and internally, weakly spined ; tibia of first 

 armed externally with 3 to 5 spines, and with 1 internally at 

 the apex; protarsus with 4 externally, 2 internally, and 1 

 mesially, 4 altogether being placed along the lower apical 

 margin ; tarsus only spined apically below the claw, as in 

 the palpus ; second leg spined like the first, except that there 

 are a few more spines on the protarsus; third leg with femur 

 sparsely hairy, patella and tibia coarsely bristly above, the 

 former armed in front with a few (about 9) short spines, the 

 latter with 2 short spines in front and some half-dozen long 

 spiniform setai below ; protarsus sparsely bristly, armed above 

 with two rows of 5 to 6 stout spines and below with about 

 8 spines somewhat irregularly arranged ; about 9 spines alto- 

 gether arranged round the distal margin of this segment; 

 tarsus armed with about a dozen spines below ; fourth leg 

 with femur sparsely hairy, a few stout bristles below, thickly 

 studded with short bristles at the apex above; patella furnished 

 above with short bristles ; tibia armed below with 8 setiform 

 spines arranged in two rows ; protarsus with about 12 spines 

 below, 2 above ; tarsus armed with about a dozen spines 

 below ; claws of legs with a few teeth, 2, 3, or 4, two long 

 and strong, the others small and sometimes absent.
