DISCOVERY REPORTS 



Proboscis very robust, almost three-fourths of trunk ; maximum width near the apex 



(Fig. 46). 



Abdomen reaching a short distance beyond fourth lateral process, slightly elevated. 



Chelophore very well developed in all three adult specimens, almost as long as 

 proboscis. Scape long and rather stout, length approximately four times the distal 

 width. Chela short and thick set, length of palm twice the width ; fingers widely gaping 

 when closed. 



Palp nine-jointed^ as in the majority of the species of Amniothea; fourth segment 

 rather longer than second (1-24 : i); seg- 

 ments 1-4 together as long as proboscis; 

 terminal segments rather setose. 



Ovigers each carrying a large mass of de- 

 veloping ova and larvae; segments 6-10 of 

 the usual type ; segments 2-4 subequal and 

 each slightly shorter than segment 5. 



Third leg long and siont; femur the longest 

 segment; second coxa slightly longer than 

 the sum of first and third. Terminal seg- 

 ments as represented in Fig. 47 a and 

 similar in all four limbs. 



Setides arranged in distinct longitudinal 

 bands on the legs; they also occur on the 

 abdomen, the transverse trunk ridges, lateral 

 processes and chelophores. 



The female shows the usual sexual differ- 

 ences of oviger and walking legs ; the femur is more robust, being scarcely more than 

 seven times as long as wide as against nine times in the male. The setules are also fewer 



in number.
