JsometniH hituberculatus, sp. n. 



Colour (in alcohol) variegated Avith fuscous above, pale 

 beneath, the biachium almost entirely fuscous, fulvous only 

 at its distal extremity ; manus fulvous, dactyli fuscous in 

 their distal half, posterior half of the fifth caudal segment 

 fuscous, lower half of vesicle and distal half of aculeus 

 fuscous. 



Cephalolhorax coarsely granular throughout, the granules 

 showing a distinct tendency in some parts to constitute defi- 

 nite keels ; the posterior median keels well marked, slightly 

 diverging in front ; the median eyes large, the tubercle 

 granular at the sides. 



Tergites coarsely granular, the median keel well marked ; 

 a tubercle on each side of the median keel on the posterior 

 margin marks the position of the lateral tergal keels charac- 

 teristic of, e. g., Buthus ; the lateral keel on the seventh 

 tergite subequal in length, with the posterior granule a little 

 longer. 



Stermtes mostly smooth, the fourth and fifth granular at 

 the sides ; the fifth marked with four granular keels, the 

 lateral of which almost attain the posterior margin. 



Tail moderately strong and long, the first, second, and 

 third segments furnished with ten strong granular keels, the 

 fourth with eight keels and merely vestiges in front of the 

 supernumerary median lateral keel, all the intercarinal spaces 

 more or less granular ; the posterior granule of the four 

 superior keels on the first three segments and of the two 

 superior keels on the fourth segment a little larger than the 

 rest ; the fifth segment with its intercarinal spaces coarsely 

 and subserially granular, smooth and depressed in the middle 

 line above. Vesicle of average form, distinctly granularly 

 carinate beneath, the aculeus elongate and curved. 



Palpi, humerus, and brachium with their keels strongly 

 developed, granular, the intercarinal spaces finely granular ; 

 manus narrower than the brachium, above bearing distinctly 

 granular keels ; dactyli long, slender, and curved, in contact 

 throughout their length. 



Legs granular and carinate ; the posterior two pairs with 

 small tibial (tarsal) spur. 



Pectines short, furnished with 11-12 teeth. 



Measurements in millimetres. — Total length 16, length of 

 tail 9, of cephalothorax 2*5, of manus and dactyli 3, of 

 dactyli 2.
