fourth leg and than protarsus + tarsus of the fourth; its 

 width equal to patella + tibia of second leg. 



Legs 4, 1,2, 3, fourth exceeding first by about half the 

 length of its tarsus. 



Measurements in millimetres. — Total length 33; carapace 

 13*5; first leg 33, second 30, third 28, fourth 35 ; patella + 

 tibia of fourth 125, of first 12. 



Log. Duaca, Estrado Lara in Venezuela. A single adult 

 female. 



This species may be known bj the unusual shortness of its 

 legs and the coloration of the abdomen, which suggest that of 

 the young A. avicularia. In no other species known to me 

 is the carapace longer than the pateUa-f tibia or protarsus + 

 tarsus of the fourth leg. In the presence of a pale fringe at 

 the extremity of the tibije and protarsi of the legs may be seeu 

 similarity to A. Walchenaerii.

(^ . — Colour. Carapace covered with a thick felting of 

 olive-yellow hairs, shining with silky lustre, similar hairs 

 present also upon the upperside of the basal segments of the 

 legs and palpi and upon the summit of the mandibles ; pre- 

 vailing tint of legs mouse-brown ; upperside of abdomen with 

 its greyish integument covered with erect bristles of a dark 

 brownish hue; ventral surface sooty velvety black; scopulse 

 olive-grey. 



Carapace a little longer than wide, its length equal to that of 

 tibia of second leg, a little less than that of fourth, and shorter 

 tiian protarsus of fourth by about one fourth of its length, 

 and about as long as patella + tibia of palp and as femur of 

 third leg. 



Legs long, 4, 1, 2, 3, thickly fringed; patella -f- tibia of 

 second as long as those of fourth ; first leg (from base of 

 femur) about four and a half times as long as carapace. 



Falp (from base of femur) about twice as long as cara- 

 pace ; palpal organ long, distinctly longer than patella of palp 

 and about half as long as the carapace, the bulb less globular 

 and the spitie much longer than in F. Cambridgii ; viewed 

 from the outside, the posterior border of the spine is continuous 

 with that of the palp. 



Slridulating-spines on maxilla consisting of a row of nearly 

 a dozen spines, which, except for their thickness and darker 

 colour, are but little differentiated from the oral fringe ; on the
