length along upper side just about double its width at base of large- 

 anterior tooth ; the posterior surface and generally also the posterior 

 part of the upper surface quite smooth ; the rest of the superior 

 surface finely but often weakly granular, with well- developed 

 anterior crest. 



Hand stout and strongly convex anteriorly in both sexes, its 

 width slightly exceeding that of the tibia in the ? and young <? but 

 considerably exceeding it (by about one-third) in the ad. S' ', the 

 length of the tibia, therefore, sub-equal to (or slightly exceeding) 

 twice the width of the hand in the $ and young g- , and a little more 

 than IJ times this width in the ad. 3 . Length of movable finger in 

 2 about If, in ad. $ about 1^ times the length of the hand-back ; 

 this finger normally with 12-13, rarely only 11, anterior flanking 

 teeth, the main rows in the middle third of the finger composed of 

 4-7 teeth (including the enlarged basal tooth of each row) ; in the 

 oblique rows of 3 enlarged teeth on both fingers the anterior tooth is 

 distinctly distal to the line joining the middle and posterior one in 

 the 3 , but to a lesser extent (sometimes scarcely at all) in the ? . 



Legs. — Femora weakly granular externally, tibiae smooth, some- 

 times very weakly granular in ^ . 



Pectines with 33-35 teeth in the ? and 39-41 teeth in the <? , the 

 posterior basal lamella of the scape enlarged and produced into a 

 broad lobe behind in the ? , normal in the ^ . 



Measurements of largest ? . — Total length 84; length of cephalo- 

 thorax 10, width 10 ; distance of eyes from anterior edge 4, from 

 posterior edge 5^; length of femur of pedipalp 7, of tibia 7^, of 

 hand-back 4, of movable finger 8 ; width of femur 21, of tibia 3h, of 

 hand 4 ; length of tail 52 ; length and width of first caudal segment 

 7, 5i, of second 7f , 5i, of third 8, 5f , of fourth 8^, 5^, of fifth 9|, 5i, 

 of sixth 10, 42 ; height of first segment 4i, of third 5, of fourth 41, 

 of fifth 4| ; length of upper surface of first segment 4^, width of this 

 surface in its middle 3^. 



Of largest ^ . — Total length 68 ; length and width of cephalo- 

 thorax7i; distance of eyes from anterior edge 2|, from posterior 

 edge 4 ; length of femur of pedipalp 5^, of tibia 6, of hand-back 

 nearly 5, of movable finger 6|- ; width of femur 1-i, of tibia almost 3, 

 of hand 4 ; length and width of first caudal segment 5^, 4f , of second 

 6, 4f , of third 61, 4f , of fourth 7, 4i, of fifth 7|, 4, of sixth 81, 3 ; 

 height of first 3 segments 3f , of fourth 3|, of fifth 3i ; length of 

 upper surface of first segment 3f, width of this surface in its^ 

 middle 2t.
