of the humeral and radial joints. The cephalothorax is long, 

 compressed before, rounded on the sides, gibbous in the middle, 

 glossy, and has a small circular indentation in the medial line ; 

 the colour of the anterior part is red-brown, diminishing gra- 

 dually in breadth towards the medial indentation, near which it 

 terminates in a point ; the sides are tinged with the same hue, 

 and the colour of the remaining portion is yellow-brown. The 

 falces are long, conical, vertical, and armed with a curved fang 

 and some long and very fine teeth near the extremity, on the 

 inner surface ; the maxillae are straight, except at the extremity, 

 which is somewhat enlarged, obliquely truncated on the inner 

 side, and curved upon the lip; the lip is large, longer than 

 broad, and rounded at the apex. These parts are of a red-brown 

 colour, the extremity of the maxillae and lip having a yellow- 

 brown hue. The sternum is heart-shaped, and of a pale reddish- 

 brown colour, with a transverse dark red-brown line between the 

 coxse of the second pair of legs. The eyes are disposed on the 

 anterior part of the cephalothorax, and are unequal in size ; the 

 two anterior eyes of the four intermediate ones are the largest 

 of the eight, are seated on a prominent tubercle, and are wider 

 apart than the two posterior ones, and those of each lateral pair, 

 which are the smallest, are placed obliquely on a minute tubercle, 

 and are contiguous. The abdomen is short, broad, thinly clothed 

 with hairs, convex above, and projects over the base of the ce- 

 phalothorax; the upper part is of a pale-yellow colour, finely 

 reticulated with reddish-brown ; on each side of the anterior part 

 there is a conspicuous, oval, yellowish-white spot bordered with 

 reddish-brown ; to these spots succeed four pale, narrow, trans- 

 verse bands bordered by fine reddish-brown lines which are 

 confluent in the medial line; and a large triangular reddish- 

 brown spot, having its vertex directed forwards, and comprising 

 near its base a small spot of a dull yellowish hue, is situated 

 immediately above the spinners ; at the extremity of the under 

 part there is a large, reddish-brown, and somewhat crescent- 

 shaped mark whose extremities extend to the sides ; the sexual 

 organs are rather prominent, and of a dark reddish-brown co- 

 lolour, with a longitudinal yellowish -brown septum in the 

 middle. 



The male differs from the female in several particulars : it is 

 smaller, the cephalothorax is shorter, and, with the falces and 

 sternum, is of a pale dull-yellow colour ; a transverse red-brown 

 line occurs on its gibbosity, and there is a fine line of the same 

 hue across the sternum, .between the coxse of the second pair of 

 legs. The maxillae and lip have a yellowish-brown hue. The 

 colours of the abdomen are paler in the male than in the female, 

 but the design formed by their distribution is the same in both
