and Species of Scorpions. 323 



stouter, the segments more excavated above ; vesicle much 

 more globular than in novce-hollandice, being wider, higher, 

 and shorter ; aculeus also shorter and rather more curved. 



Palpi almost as in novce-hoilandicej but the hands more 

 robust. 



The following measurements in millimetres of the type of 

 this species (A) and of an example of novce-hollandice (B) of 

 the same sex and nearly the same size will show the diffe- 

 rences between the two species with respect to the size of the 

 tail and hands : — 



A. Total length 48'5, of carapace 6'8, of tail 26 ; length of 

 tail-segments 1 to 5, 2'7,3'1,3'5, 3"8, 5'8; width of the same 

 segments, 3'5, 3T, 3, 2'7, 2*5; vesicle, width 2"6, height 2, 

 length 33; length of aculeus 2*3; width of brachium 2"1, of 

 manus 5*5 ; length of hand-back 5"1, of movable digit 6*5. 



B. Length of carapace 7, of tail 29 ; length of tail-segments 

 1 to 5, 3, 3'5, 3'9, 4*2, 7 ; width of the same segments, 3"2, 3, 

 2'9, 2*7, 2*5; vesicle, width 2"4, height 1*9, length 3"8 ; length 

 of aculeus 3; width of brachium 2*5, of manus 4'5 ; length 

 of hand-back 5'6, of movable digit 6*2. 



Unfortunately I have only the one specimen of U. Wood- 

 wardti for examination; but small examples of novce-hollandice 

 from Perth, both older and younger tlian the one measured, 

 show similar differences to it from the type of U. Woodward ii. 

 This species also differs from novce-hollandice in being much 

 smoother and in having the frontal lobes of the carapace more 

 rounded. In both these respects, as also in the robustness of 

 the hand, it approaches U. abruptus^ but in the latter the 

 superior caudal keels are more elevated and posteriorly spini- 

 form.

Scorpiops Petersii, sp. n. (PI. XIV. fig. 10.) 

 Scorpiops Ilardioickii, Peters and Karsch (not of Gervais). 



Colour blackish brown ; feet, vesicle, and chcliceraj yellow, 

 with a smooth yellow spot at the extremity of the upper edge 

 of the femur and a similar spot on the anterior face of the 

 second segment of the palj)i. 



Carapace granular throughout, but not coarsely, the median 

 groove smooth ; the anterior border deeply excised, with
