Cep7ia7o#/io?Y<iC as high behind as it is long; the posterior slope curved in- 

 wards, but almost perpendicular; profile of upper side of caput 

 slightly convex, an.d sloping a little forward. The caput is exceed- 

 ingly large, absorbing, in fact, almost the whole cephalothorax. 

 Looked at fi-om above, its upper surface forms nearly a square; the 

 sides are perpendicular. 



Height of clypeus less than the diameter of the fore central eyes. 



Ocular area slightly broader than long, and equal in breadth before and 

 behind; fore central pair of eyes very large, and of a dull, pearl-grey 

 hue; f(. re laterals in a line with base of fore centrals, and of same 

 color; posterior pair a little smaller than fore laterals, and as nearly 

 as possible equally divided from them by the minute, intermediate 

 eye, which is placed a little inside of their straight line. 



Legs moderately long, tolerably strong, 1, 3, 2, 4; first pair much the 

 strongest. Armed with spines, and with a small claw-tuft beneath 

 the terminal tarsal claws. 



Falces long, straight, divergent, and directed forward ; denticulations small; 

 fang of moierate length and strength. 



Maxillae long, strong, straight; widened on both sides at the extremities, 

 which are rounded. 



Labium long, about two thirds the length of the maxillae, and narrower 

 at the apex than base; apex rounied. The direction of the maxillae 

 and labium is very nearly perptndiculdr (or at riglit angles) to the 

 sternum, which is small, nearly round, slisj;htly pointed behind and 

 truncated in front; the truncation is very gently curved, the con- 

 vexity of the curve directed backwards. 



Abdomen small, short, oval, very convex before, and fitting up pretty 

 closely to the incurved thorax.
