Urodacus excellens, Poc. 



Urodacus excellens Poc. Ann. & Mag. Nat. Hist. (6) ii. p. 170, pi. viii. 

 fig. 2 (1888). 



Loc. North Australia, Port Essington in Arnliem Land 

 {Dr. Bichardson). 



Urodacus nova' hollandi'w, Peters. 



Urodacus novts-hollandia, Peters, Mon. Berl. Ak. 1861, p. 51 1 ; Pocock, 

 Vim. & Mag. Nat. Hist. (6) ii. p. 170, pi. viii. tig. 1 (1888). 



Loc. Western Australia (Freemantle, Perth, Swan River). 



In the monograph of the species of this genus published in 

 1888 I referred to some specimens of what I supposed, and 

 still suppose, to be novce-hollandia', Peters, in the British 

 Museum, ticketed " Ceylon." That the locality is erroneous 

 has been to my mind settled conclusively by the subsequent 

 discovery in the Museum of some specimens of a Centipede 

 (Cormoctphalus aurantitpes, Newp.), which is apparently not 

 uncommon near Perth, also bearing the label "Ceylon," accom- 

 panied by the same register number as that under which the 

 scorpions were entered. 



1 am not acquainted with any evidence that this species 

 ranges far from the south-western corner of Australia. A 

 specimen from Port Lincoln that I at one time referred to it 

 is the young of another species. 



Urodacus granifrons, sp. n. 



J. — Colour a tolerably uniform ochre-yellow.

 rated by a shallowish median emargination as in novai- 

 hollandice \ the interocular triangle covered with fine close-set

Tail nearly five times as long as the carapace, the sides of 

 the segments convexly rounded, the second a little longer than 

 broad, the fifth more than twice as long as broad ; the supe- 

 rior crests weakly granular, not posteriorly elevated ; inferior 

 crests of segments 1-3 smooth ; lateral surface of segments 

 2-4 very finely granular; vesicle as wide as fifth segment. 



Legs with finely granular femora ; 5 spines on outer side 

 of protarsus of first and second leg.
