j\Ir. S. Hirst on neio Scorpion ft. 471 



tliis subspecies in tlie follo^vino- details, none of wliich seem 

 to nie to be of much importance: — Hand a little more 

 swollen, its lobe not quite so well developed and with the 

 edge thicker ; keels of the upper surface slightly stronger ; 

 movable finger with a somewliat larger lobe. Upper keels 

 of tail slightly stronger. Colour deep reddish brown ; the 

 upper surface of the trunk has no distinct markings, the legs, 

 however, are variegated ; tail rather a light reddish brown 

 above, and the vesicle is ocliraceous except at the sides, whicli 

 are dark; hand paler than the trunk, but its keels are 

 blackish. 



Pectinal teeth 5 in number. 



Measurements in mm. — Total length 44 ; length of cara- 

 pace 6, of hand-back 5"4, of movable linger 6*25; width of 

 hand 6. 



Material. — A single adult male, found by Mr. H. 0. 

 Kobinson under moss on a tree at Bukit Besar, Malay Penin- 

 sula, on the 27th of August, 1901. 



Scorpioj^s austerus, sp. n. 



(^ . — Last sternite with weak keels, which vary considerably 

 in strength in different specimens ; in some they have ahnosfc 

 disappeared. 



Width of hand considerably greater than the length of the 

 hand-back, the lobe greatly developed. Its upper surface is 

 furnished with numerous fine ridges, most of which have 

 fused with one another and form an irregular network ; these 

 ridges are smoother than in the female, usually they are 

 obsoletely granular, but sometimes quite smooth. Inner 

 edge of hand very different in appearance to that of S. in- 

 scu/ptus, Poc. ; it is strongly compressed, and a strong keel, 

 which is either smooth or indistinctly granular, runs along 

 the distal half of it. Keel of hand-back usually weakly 

 granular, but sometimes smooth. Finger-keel strong and 

 well developed throughout its length and often quite smooth, 

 but sometimes (especially at the basal end) it is weakly 

 granular. There is no trace of the weak inner crest which 

 is present on the lobe of the band of S. inscidptus. Movable 

 finger considerably longer than the hand-back. Pores of the 

 lower surface of the hand and tibia exactly the same in 

 number as in S. inscidptus. 



? . — Hand narrower and its lobe less developed than that 

 of the male, but its width is greater than the length of llie 

 hand-back. Its inner edge is not quite so compressed and 

 usually has a weaker keel than is the case in the male. The
