Female Body elongated oval. Abdomen slightly contracted 

 immediately behind its junction with the cephalothorax. The 

 latter small and narrow in front, where it is rather deeply 

 notched, the notch however being divided by a central projection. 

 Eye-eminence small, longer than high (fig. 3 a), oval when seen 

 sideways, narrow above, the crests on its summit being near to- 

 gether ; these are each furnished with five or six small blunt teeth. 

 Between the eye-eminence and the anterior margin of the thorax 

 are two elevated ridges, each armed with a row of three or four 

 rather large teeth, enclosing a smooth narrow space between 

 them. Several other sharp tubercles or teeth are scattered along 

 the lateral parts of the thorax. Colour of the cephalothorax 

 yellowish-gray, mottled with white. Abdomen ash- or fawn- 

 coloured, without a distinct dorsal band, though the central part 

 of the back is darker than the rest. Upper surface variegated 

 with dark semilunar transverse marks and small whitish spots. 

 Under surface of the body white, marked with brown or black. 

 Palpi small, joints without projecting angles. Falces weak. 

 Legs long, slender, and nearly smooth ; femora of second pair 

 longer and thinner than the rest ; coxae and trochanters spotted 

 with black, the other joints annulated with brown and white 

 rings. 



Male. Body short and broad. Abdomen small and depressed. 

 Cephalothorax largely developed, being nearly as long as the 

 abdomen, rugose, and having the tubercles and teeth on its sur- 

 face much larger and more numerous than in the female. Cepha- 

 lothorax separated from the abdomen by two strongly marked 

 rings or ridges. Palpi dindi falces stronger than in the female; 

 legs very long, and armed with short black spines or bristles.
