smooth ; 5th segment with the sides of its upper surface granular, 

 its lateral surface also finely granular, lower surface with the 

 granules forming two intervening crests. Vesicle globular, wider 

 than high, granular below ; aculeus lougish. 



Palpi long, humerus as long as the carapace ; brachium three 

 times as long as wide, with the two superior crests well developed 

 and granular, the upper crest of the posterior surface also 

 present ; manus long and wide, much wider than the brachium, 

 smooth, punctured, its width about two-thirds the length of the 

 hand-back, and the hand-back about two-thirds the length of the 

 movable digit ; digits separated at the base, lobate and sinuate ; 

 movable digit with 14 (15) median rows of teeth. 



Legs with smooth coxge and granularly crested femora ; tarsi 

 with two parallel rows of black spinules beneath ; the distal 

 tibial segment also with a row of spinules on its posterior side.

In his recent revision of the Scorpions of the family Androcfo- 

 nidcB, Prof. K. Kraepelin has recognized two species as composing 

 the genus Prionurus (called by him Androctonus). These are 

 funestus of Hempr. & Ehrenb., which is identical with australis 

 of Linnaeus, and crassicauda of Olivier ; and on pp. 20-28 he has 

 compiled a series of most elaborate tables of comparative measure- 

 ments of the species he cdlXs funestus. One cannot but admire tbe 

 patience and labour displayed in this work ; but to my mind 

 the efforts that have been made to show the variability of this 

 species are of but little value, inasmuch as they have been carried 

 out without any regard to geographical distribution. Our author, 

 in fact, begs the whole question, by assuming what in reality has to 

 be proved, namely, that he is dealing with but one species. It is 

 evident that similar tables could be prepared for every genus, 

 and with the exercise of a little ingenuity the whole of the 

 Buthid(B could be reduced to but one species. 



Turning, however, to the facts, we find that he establishes the 

 characters of his so-called s^Qcie?, funestus upon 150 examples.
