them granular, the keels much more closely so than the spaces, the 

 inner edge of the manus sub-denticulate , the anterior surface furnished 

 with two weakly granular keels, the total number of keels or ridges 

 on the manus amounts to nine ; digiti curved , the movable longer than 

 the hand-back. Chelicerae with the movable dactylus armed above 

 with three teeth (the first small) and the terminal fang, below with a 

 series of small subequal teeth and the terminal fang; the immovable 

 armed below with a series of small , subequal teeth , and above with 

 two teeth, of which the posterior is bifid, and the terminal fang. 



Legs nearly smooth; claws free, distal tibial segment longer than 

 the proximal. 



Sternum longer than wide; genital plates separated. 



Pectines short, with 4 — 4, 6 — 7 teeth, the apical of which is in- 

 flated, the proximal fulcrum the largest, the shaft composed of two 

 segments, whereof the distal is very small. 



Measurements in millimeters. Total length 29; céphalothorax, length 

 4.3, width 4; tail, total length 15.3, length of 1 st segm. 1.8, of 

 2 nd 2, of 3 nd 2.2, of 4 th 2.4, of 5 th 3.7, of vesicle and aculeus 4.2; 

 width of 1»* 2.2, of 2^ 2, of 5th 1.6, of vesicle 1,6; height of h^ 

 1.5, of vesicle 1.6; humerus, length 3.4, width 1.5; brachium, length 

 3.5, width 1.7; manus, length 4, width 2.8, length of hand-back 3.6 , 

 of movable digit 4.4. 



This species, may be immediately recognised from the preceding, 

 Ch. variegatus, by its much narrower hand. In C. variegatus as may 

 be seen by the table of measurements the length of the „hand-back" 

 is, less than the width of the hand. 



In Ch. borneensis, Simon, which is unknown to me, the manus is 

 even wider than in variegatus. 



This new species then, appears to come nearest to Ch. truncatus 

 of Karsch, in the form of the hand. This species also is unknown 

 to me , but it appears to differ from Ch. cavernicola in many particulars , 

 such as the keeling of the tail , the length of the 3 rd and 4th segments 

 of this organ as compared to the 5* h , the length of the „hand-back" 

 as compared with the movable digit etc.
