and Species of Scorpions. 327 



Stergites smooth, the last furnished with four weakly 

 granular keels. 



Tail short, only about three times the length of the cara- 

 pace, posteriorly attenuate, the second segment as wide as 

 long and about half the length of the fifth ; the keels deve- 

 loped as in tlie preceding species, except that the upper ones 

 on the second to fourth segments have the terminal denticle 

 enlarged and bifid ; vesicle long, compressed, as wide as the 

 fifth segment, as high as wide, almost smooth beneath. 



Palpi long, the humerus about as long as the carapace ; all 

 the normal keels well developed and granular, the spaces 

 between them also somewhat coarsely granular ; brachium 

 with ten pores on its lower surface and two very large and 

 sharp teeth, as well as a few smaller ones on its anterior 

 surface ; hand not nearly twice as wide as the brachium, 

 narrow, more than twice as long as wide, the hand-back 

 nearly twice as long as the width of the hand and slightly 

 longer than the carapace ; the movable dactylus a little longer 

 than the hand-back ; the immovable digit nearly four times 

 as long as it is wide at the base, the inner edge of the digits 

 nearly straight. 



Legs externally granular. 



Pectines furnished with 8 teeth. 



Length about 50 millim., of carapace 9"3, of tail 27*5 ; 

 width of brachium 3'5, of manus 5 ; length of hand-back 9, 

 of movable digit 9'8. 



A single female example from Silhet. 



This species appears to differ from S. montanus of Karsch 

 in having the carapace and palpi coarsely instead of very 

 finely granular, and in having the movable digit longer 

 instead of shorter than the hand-back. 



From anthracinus, Simon, it may be recognized by having 

 ten pores on the lower surface of the brachium instead of 

 nineteen, and from S. Lindstroemii and luguhris by having 

 ten instead of fifteen of these pores. 



Scorpiops Binghamii, sp. n. (PI. XIV. fig. 13.) 



Colour nearly black, the tergites obscurely spotted with 

 ferruginous; the lower surface and the feet ochraceous or 

 ferruginous, the vesicle ferrugineo-fuscous. 



Carapace and tergites distinctly but not very coarsely 

 granular, the superciliary crests pronounced ; ocular tubercle 

 cleft above, the eyes large and separated by a space that is 

 about equal to a diameter; the postero-lateral eye the smallest, 

 the space dividing it from the median eye greater than the 

 space between the anterior and median eye and a little smaller
