76 Mr. K. T. Pocock on 



above, weakly granular laterally, the anterior excision 

 normally strong, with the triangular piece at the apex of it ; 

 distance between the anterior and median lateral eyes greater 

 than that between the median and posterior. 



Tcrgites weakly grannlar posteriorly and laterally, the last 

 with two nearly obsolete granular keels on each side. 

 Sternites smooth, the last only very obsoletely carinate. 

 Tail about three and a half times the length of the cara- 

 pace, robust, the sides of the segments convex in outline, the 

 second segment as long as wide, the third longer than wide ; 

 in segments 1-4 the superior keels are weakly granular, more 

 strongly so on the fourth ; the supero-lateral keel merely 

 subcrenulate ; the inferior keels smooth, roughened with 

 punctures, these keels on the first and second segments 

 strongly and equally developed, the superior and the lateral 

 intercarinal space weakly granular ; the fifth segment with 

 denticulate inferior keels and the posterior lateral tooth very 

 strong, the upper surface granular at the sides ; vesicle 

 narrower and lower than the fifth segment, not very robust, 

 serially denticulate beneath. 



Palpi. — Humerus lightly convex and sparsely granular 

 above, the anterior and posterior keels strong and granuh'\r, 

 the lower and posterior surfaces smooth, the posterior-inferior 

 keel weak ; hracMum smooth, except for a few small granules 

 in front, longitudinally costate ; manus large, nearly the same 

 shape as in S. inegacepJiahis, but with its inner border a little 

 more convex and almost entirely smooth, the angle formed by 

 the meeting of the inner border of the hand and of the 

 immovable digit very obtuse and nearly evenly rounded, the 

 upper sui-face evenly convex from the keel of the hand-back 

 to the inner edge, the area above the keel of the hand-back 

 sloping and not vertical when the hand is normally at rest ; 

 the upper surface covered with low, often anastomosing 

 tubercles, which form four smooth keels, three of which 

 emanate from the immovable digit; the inner edge of the 

 hand at the base of the immovable digit is raised into a 

 distinct smooth crest ; the width of the base of the immovable 

 digit equal to nearly half its length ; the movable digit 

 shorter than the length of the hand, but a little greater than 

 its width ; the length of the hand-back much less than the 

 greatest width of the hand, but greater than the least width, 

 I. e. at the base of the digits. 



Legs almost entirely smooth, femora of the fourth pair very 

 weakly granular ; the feet with 5-4 spines below. 



Pectines with lo~14 teeth ; the basal intermediate lamella 

 not elongate, so as to leave a long space between the point
