obtained in Queensland. Dr. Broom, who collected this 

 scorpion himself, also procured a specimen of what is perhaps 

 the female of the same species at Hill Grove, New South 

 Wales. 



Genus Ch^erilus, Simon. 

 Chcerilus agilis, sp. n. 



$ . — Colour dark reddish brown, not distinctly variegated ; 

 vesicle, legs, and lower surface paler ; hands ferruginous, with 

 black keels and black digits. 



Carapace with its anterior interocular area almost smooth, 

 weakly granular in front ; the rest granular, longer than the 

 first and second and as long as the fifth caudal segment. 



Terga closely granular, with a pair of posterior tubercles ; 

 the fourth with a pair of granular crests on each side. 



Sterna smooth ; third with a polished median posterior 

 triangular area ; fifth with a short series of granules on each 

 side. 



Tail about four times as long as carapace, slender ; first 

 segment a little wider than long, second a little longer than 

 wide, fourth nearly twice as long as wide, fifth more than three 

 times as long as wide : inferior keels of the first segment obso- 

 lete ; of the second represented by a few granules; a little 

 more granular on the third ; the rest of the keels strong and 

 coarsely granular; the median lateral represented by a few pos- 

 terior granules on the second, third, and fourth, extending over 

 two thirds of the lateral surface of the fifth segment ; upper 

 edges of the fifth rounded, granular, but not carinate, inferior 

 crest of the segment posteriorly bifid ; vesicle smooth, sparsely 

 punctured, a long oval in shape, not flattened below, as 

 wide as the second caudal segment ; intercarinal spaces of tail 

 smooth, except the superior, which are weakly granular. 



Chelm long and slender ; humerus weakly granular above 

 and below ; the crests granular; the upper and lower crests 

 bounding the anterior surface converging and fusing into 

 a single crest in the distal half of the anterior surface : 

 brachium longer than carapace, smooth, its posterior crests 

 smooth ; superior and inferior anterior crests granular, the 

 latter uniting distally with a strong granular crest on the lower 

 half of the anterior surface : hand long and narrow, the hand- 

 back almost twice as long as the width of the hand and 

 slightly longer than the carapace ; in addition to the two keels 

 which border the hand-back there are four strong keels, and 

 two weak keels, one on the outer surface of the hand and 

 the other on the inner surface ; the hand-back keels granular
