? . — Colour. Carapace yellow, vai'iegated with five longi- 

 tudinal black bands, one median extending from the anterior 

 border across the tubercle almost to the hinder border, one 

 on each side passing backwards from the lateral eyes, and 

 one on each lateral margin, whence patches of the same colour 

 pass inwards, near the side of the posterior border there is on 

 each side a distinct patch ; terga yellow, with three longi- 

 tudinal black bands, one in the middle and one on each side ; 

 these do not spread on to the seventh tergite ; tail pale 

 yellow, except for three rather indistinct fuscous spots on the 

 lower surface of the second, third, and fourth segments, one 

 in the middle and a pair at the posterior end ; chelse yellow, 

 digits alone black in their basal half; legs yellow, faintly 

 spotted with black, one spot in the middle of the femur, 

 another on the patella, and one at the base of the two tibial 

 segments. 



Carapace as long as the first and half the second caudal 

 segments, finely granular throughout, but not crested ; ocular 

 tubercle low, with smooth ridges. 



Terga finely granular, the median crests distinct, granular, 

 the lateral crests on the last strong and granular. 



Sterna sraootli, punctured, the last with neither granules 

 nor crests. 



Tail nearly five times as long as the carapace, the fourth 

 segment a little wider than the fifth, third, and second, and 

 equal to the first ; segments almost smooth, only minutely 

 granular when examined with a high power ; keels all weak 

 and scarcely to be called granular, the lower surface of the 

 third, fourth, and fifth segments without visible keels. 



ChelcE almost smooth, the crests very weakly granular ; 

 hand without crests, smooth, wide, a little wider than the 

 brachium, the width equal to nearly half the length o£ the 

 movable digit, which is only one third greater than the length 

 of the hand-back ; digits short, unmodified, the movable with 

 7 median rows of teeth (including the small apical set and 

 regarding the long basal row as single), 7 larger external 

 teeth, and 7 larger internal ones. 



Legs weakly granular. 



Pectines wii\\ 19 teeth. 



Measurements in millimetres. — Total length 51 ; carapace 

 5"5, tail 28, of movable digit 5.
