greater than that of the other segments together. 

 Cephalon is much expanded in front, neck fairly narrow 

 but not particularly long. 



Proboscis large and stout, expanded in mid-region and 

 tapering towards each end, the whole organ somewhat 

 pear-shaped with smaller end forward. 



Chelifori well developed, scape uni-articulate, expaaid- 

 ed distally, about same length as proboscis, hand power- 

 fully developed with fingers shorter than the palm, 

 fingers crossing at the apex and possessiing a large number 

 of fine teeth. 



Palps five-jointed, first joint very small, second joint 

 longest equalling the third and fourth taken together, 

 fourth less than half the third, fifth joint long but a little 

 shorter than the second, fourth and fifth joints finely 

 I setiferous, occasional spines on other joints specially 

 towards end of third. 



Ovigers. — Ten-jointed with terminal claw, situated on 

 slight ventral outgrowth in front of first pair of legs. The 

 proximal joints increase in length from the first, which 

 is small, to the fifth, which is the largest joint of the 

 limb; fourth joint is rather swollen and expanded distally; 

 the fifth joint is long and narrow bearing distally a fringe 

 of long delicate haii's, as does also the sixth. This joint 

 is about one third the length of the fifth. The seventh, 

 eightli, ninth and tenth joints are about equal in length, 

 all gently curved and bearing pinnate spines. These 

 spines vary in shape. In the ovigerous male they are 

 arranged in a single row on each joint. The middle 

 spines of each row are long and stiletto-like, finely toothed 

 on each edge, while at either end of row they may become 

 worn to a ro'unded apex. On the terminal joint, the 

 spines become particularly worn. The teiininal spine is 

 long, simple and hook-shaped. 



Ocular tubercle low and rounded, visual elements large 

 and of equal size. 



Abdomen cylindrical, slightly t-apering posteriorly, 

 and projecting upwards. 



Legs. — The proportions of the joints vary somewhat 

 from those given in the original descriptions. The length 

 of the first and second coxae are as stated by Haswell ; 

 the third coxa is a short joint less than half the length of 

 the second ; femur over six times the length of the third coxa 

 and a little shorter than the first tibia, femur swollen (es- 

 pecially so in the female) and slightly curved; first tibia is 

 as usual long and narrow ; second tibia extremely long, being- 

 equal in length to the femur and first tibia together;
