Scorpions of the Genus Urodacus, Pet. 63 



Loc. Chapman River, 10 miles from Geraldton, W. Aus- 

 tralia (E. H. Saunders). 



This species, based upon a single male example, differs 

 from U. novce-hollandice in having the anterior portion of the 

 carapace finely granular, instead of smooth and finely 

 punctured. 



Urodacus abruptus, Poc.

 Urodacus Keyserlingii, Pocock, Ann. X: Mag. Nat. Hist. (6) viii. p. 245 



(=novce-hollandice, Keyserling, not Peters). 



Loc. South and South-eastern Australia, Adelaide, type 

 (59. 62) ; Ballaratand Bendigo, in Victoria (W. IV. Froggatt) ; 

 Coo ma, Bathurst, Maitland, Yass, in New South Wales 

 (W. W. Froggatt)', New England District of New South 

 Wales (J. Macpherson) . 



Since I described this species the British Museum has 

 received a very fine series of it from Mr. Froggatt and 

 Mr. Macpherson from the localities mentioned above. 



Urodacus Woodwardii, Poc. 



Urodacus Woodwardii, Poc. Ann. & Mag. Nat. Hist. (6) xii. p. 322, 

 pi. xiv. fig. 8 (1893). 



Loc. Darling Range, north of Perth, W. Australia (B. II. 

 Woodward) . 



This species is most nearly related to U. abruptus, but is 

 recognizable from all the examples of the latter that I have 

 seen in having the segments of the tail more convexly rounded 

 and lower, with less elevated upper crests, so that the areas 

 between these crests and the superior lateral crests are 

 noticeably narrower than in abruptus. Moreover the vesicle 

 is distinctly more globular, its width excelling that of the 

 fifth segment. 



Urodacus ormatus, Poc. 



Urodacus armatus, Poc. Ann. & Mag. Xat. Hist. (G) ii. p. 172, pi. viii. 

 tig. 3 (1888). 



Loc. S. Australia, Port Lincoln, on the west of Spencer 

 Gulf. 



This species, of which only a single male example is known, 

 is most nearly related to the Perth species, but may be at 

 once recognized from the male of it by the strong armature 

 and greater slenderness of the tail-segments.
