538 ME. E. I. POCOCK ON THE 



carapace and clielse ; two postero-lateral spots on the carapace, 

 and two, one posterior and lateral, tlie other submedian, on the 

 principal terga. Upper surface of the trunk rather thickly 

 studded with coarse granules. 



Carapace flattish, its frontal portion lightly convex, and 

 sloped downwards at an angle of less tlian 45°. The lateral 

 eyes widely separated, the distance between tbem mucb greater 

 than half the median length of the carapace, a little more than 

 three times as great as the distance between one of the tubercles 

 and the nearest point of the lateral border, and a little more than 

 twice as great as the distance between the same tubercle and the 

 antero-lateral border (angle). The median tubercle transverse, 

 of medium height, separated from the anterior border by a 

 space which is equal to quite twice its longitudinal diameter. 

 The front border mesially depressed, very slightly emarginate, 

 considerably overlapping the median process; the denticles 

 moderately coarse laterally. 



Mandibles almost smooth above, the external distal tubercle 

 moderately prominent. 



GJielcB moderately long, robust, granulation coarse on the 

 femur, iiner on the tibia ; the distance between the lateral eyes 

 equal to about four-fifths the length of the upperside of the 

 tibia, and much greater than the length of the tarsus ; the 

 spines short, the longest on the tibia much less than the thick- 

 ness of this segment, and scarcely half the length of the distance 

 between the eyes ; the longest on the femur less than the height 

 of this segment, and rather shorter than the longest on the 

 tibia. The spine-armature closely resembling that of T. harha- 

 densis, but the upper edge of the tibia armed with only 7 spines, 

 owing to the absence of the normal distal spinule, and the first 

 superior spine on the tarsus very minute. 



Leffs : femur of 1st a little more than one-fourth greater than 

 the width of the carapace, and a little more than twice its 

 median length ; the femur of the 2nd about equal to the width 

 of the carapace, a little shorter than that of the 3rd, and a little 

 longer than that of the 4th ; tibia of the 2nd a little shorter 

 than the femur, and just about twice the length of the pro tarsus ; 

 tibia of the 3rd a trifle longer than the femur, and more than 

 twice the protarsus ; the three tibial segments of the 4th a little 

 longer than the femur, the second and third, taken together, 

 about three-quarters the length of the first, and a little shorter
