Description of holotype {^). Trunk compact, last two pairs of lateral processes in 

 contact proximally, the others separated by very short intervals. Cephalic segment as 

 w^ide anteriorly as long ; neck very short, base of 

 oviger occupying most of the space between 

 anterior cephalic lobe and first lateral process. 

 Ocular tubercle high (o-8 mm.), very wide at base 

 (o-6 mm.), tapering to about half that width at 

 the apex on which the four eyes are set. Setae 

 almost entirely absent (Fig. 30). 



Proboscis stout, sub-cylindrical, rounded at 

 apex, somewhat contracted at base; slightly 

 shorter than either scape or cephalic segment. 



Abdomen horizontal, fusiform, reaching to 

 middle of second coxa. 



Scape of chelophore nearly four times as long 

 as wide, with a few very minute setae at the 

 distal end. Chela shorter than scape (see measure- 

 ments), palm short, ovoid, fingers half as long 

 again as palm, much curved, each armed with 

 seven or eight long spinules ; a few fine setae on 

 proximal half of immovable finger (Fig. 29 d). 



Palp with two terminal segments together ap- 

 proximately equal to third, and three-fourths of 

 second segment (segments 2-5 in the proportions 

 10 : 7-7: 4-4: 3-2 and in female as 10 :']■% :4-8 13). 



Oviger. Terminal claw subequal to tenth seg- 

 ment and armed with 4-5 spinules. Total number 

 of denticulate spines, 26.^ Segments 4-6 as 

 represented in Fig. 27 e, and in the proportions 

 1-82 :2-55 : i. 



Third leg rather stout proximally, and tapering 

 gradually from the distal articulation of the 

 first tibia where the width is suddenly reduced to almost one-half (i.e. proximal 

 width of second is less than two-thirds distal width of first tibia, see Fig. 30 c, $). 

 Second coxa equal to the sum of the other two (dorsal measurements). Femur shorter 

 than either tibia, three times as long as wide and slightly inflated ventrally (Fig. 29 c) ; 

 no raised femoral gland tubercles are present and, indeed, no trace of gland openings 

 has been observed. First tibia the longest segment. Tarsus subequal to propodus ; claw 

 approximately half the length of the latter ; auxiliary claws very short, about one-fifth 

 of claw.
