9 . Carapace. Cephalic portion very much raised, pale brown in 

 colour and with a line of long setae down the centre ; thoracic poi'tion 

 more infuscated, especially posteriorly, to fovea ; latter procurved. 

 Length of carapace equal to patella, tibia, and metatarsus and tarsus 

 of 1st leg; and to tibia, metatarsus, and about *- tarsus of 4th leg. 

 Carapace considerably narrower opposite 3rd pair of legs. 



Eyes. Seen from above, hind margins of anterior row are in a 

 slightly recurved line, and anterior margins in a distinctly procurved 

 line ; anterior medians small, round, and nearer to anterior laterals 

 than to each other. Anterior laterals large, oval, and oblique. Pos- 

 terior row strongly recurved ; medians slightly larger than laterals, and 

 almost circular but uiisymmetrical in outline ; laterals slightly removed, 

 and oval. Ocular area at least 2.V times as wide as long. 



Abdomen long, broader posteriorly ; almost uniform dark olive-brown 

 in colour ; lung operctilae and genital plate lighter brown ; spinners 

 short and stout. 



Sternum, coxae, etc., light brown in colour ; posterior sternal sigilla 

 oval, oblique, about their long diameter from the margin and opposite 

 3rd coxae. 



Labium about as long as broad and muticous. Coxae of pedipalps 

 with a few scattered denticles at base of anterior border. 



Chelicerae stout ; rastellum composed of very stout spines ; the 

 2 anterior ones blunt and prominent, with a more inner inwardly 

 projecting smaller spine ; groove with numerous denticles down centre, 

 and 6-7 teeth down inner border ; hairs around mouth parts dull in 

 colour. 



Legs. Tarsi I and II scopulate and spineless. Tarsus III with 

 long, sparse, scopular-like hairs, and a row of 4 spines on each side of 

 upper surface, and a cluster of 3-4 spines on anterior surface distally. 

 Tarsus IV with long setose hairs, and with about 15 small spines on 

 under and anterior surface. Metatarsus I lightly scopulated, slightly 

 more densely at sides and bearing 3 apical spines, a median, and a 

 basal spine on under surface. Metatarsus II similarly spiued but 

 scarcely scopulated. Metatarsus III with 2 apical spines on under 

 surface, and a band of 10-11 small spines along each side of upper 

 surface ; and 2 apical spines on anterior surface. Metatarsus IV with 

 2 strong apical spines on basal and 2 on anterior surface ; 10-11 short 

 spines on anterior surface, and 1 apically on posterior surface. Tibiae 

 I and II with 4-5 spines in a line down centre. Tibia III with 5-6 

 spines in an irregular band down each side of upper surface. Tibia 

 IV with some setiiorm hairs on under surface, and a row of setae 

 along posterior side of upper surface. Patella III with a dense area
