Carapace low, longer than wide, shorter than patella and 

 tibia i. or iv.^ slightly longer than protaisus iv. ; fovea deep, 

 transverse. Ejes ot the anterior row strongly procurved, the 

 anterior edge of the medians being a little behind the centre 

 of the laterals, the medians being the smaller, more than 

 a diameter apart and separated from the laterals by about a 

 diameter; posteiior medians about as large as the anterior 

 medians, not very widely separated from them, closer to 

 posterior laterals, which are smaller than the anterior laterals 

 and separated from them by a space which is quite equal to 

 half a diameter of tiie latter. 



Falces with a thorn-like spur on the apical third of the 

 external surface ; fang-groove with eleven teeth on inner 

 margin, the basal one granuliform. Posterior sternal sigillse 

 £ej)arated from the margin by less than their long diameter. 



Protarsus i. and ii. scopulated almost to base ; protarsal 

 scopula iii. covering ^, with two basal spines; iv. covering 

 about ii — elsewhere strongly spined. Tibia i. with two short 

 apical spines ; ii. with tiiree apical and one inferior spines ;

Carapace, chela*, legs, sternum, and labrum mahogany-

 abundant sulphur-yellow bristles. Coxa3 of pedi[)alps and 

 margins of fang-groove with more yellowish and paler 

 bristles than usual. Abdomen narrower than ciwapace, 

 velvety black, with large light yellow bristles. 



Carapace almost as wide as long, shorter than patella and 

 tibia i. or iv. ; fovea deep, transverse. Eyes of the anterior 

 row strongly procurved, the anterior edge of the medians 

 being a little behind the centre of the laterals, nearly evenly 

 spaced, the medians being much the smaller and separated 

 from each other by a sjjace which equals their dinmeter; 

 posterior medians about as large as the anterior medians, not 

 very widely separated from tiiem, closer to posterior laterals, 

 which are smaller than the anterior laterals and sepaiated
