Description of body from a Bangkok specimen: — 



Cephalothorax slightly convex, considerably narrowed 

 anteriorly. The anterior eyes are black, they are separated by 

 a prominent elongated smooth tubercle which extends to the 

 anterior edge of the cephalothorax, which consists of a sharp 

 ridge which curves back on each side as far as the lateral eye where 

 it disappears ; the three lateral eyes are pale yellow, the dorsal 

 pair being very conspicuous in the live animal. The whole 

 surface of the cephalothorax is roughly granulated, on the 

 whole more coarsely anteriorly ; the cephalic and thoracic 

 grooves are well marked. Abdomen moderately depressed, 

 elongately oval, at its widest part 1 ; 7 wider than the widest part 

 of the cephalothorax ; upper surface granular, with the posterioi 

 edge of each segment " crenulated " ; "the muscular points" 

 are round and well marked on the second to eighth segments. 



Colour (in life) : drawn up from several dozen Bangkok 

 specimens. 



Adults : — Upper surfaces of chelce, cephalothorax, abdomen, 

 two joints of legs nearest body and lower surface of abdomen 

 very dark brown, almost black, but sometimes the greater part 

 of the lower surface of the abdomen is reddish-brown. Along 

 either side of the abdomen there is a broad pale yellow longi- 

 tudinal line. The tail, limbs (where not dark brown), lower 

 surface of cephalothorax, and the first two segments on the 

 underneath of the abdomen are a rich red-brown.
