' The evidence adduced by Lonnberg (Ann. Mag. ?fa1. Hist. (7) i. pp. 86-87, 

 1898) in favour of Lis view that the Scorpion described by De G-eer as/, mavii- 

 latiis is the S. europmus of the 10th ed. of the • Systenia ' appears to me to be more 

 cogent than the evidence in favour of the identity of Scorpio niaarus and 

 Scorpio australis of the latter work. Yet Kraepeliu in his ' Tierreich ' accepts 

 the two last, but rejects S. europaics.
