Stand to keep thera apart in separate glassbottles which had 

 been given to them for that purpose. In consequence only one 

 specimen arrived safe and sound, one was completely devoured, 

 and the swelled up abdomens of two other killed specimens 

 showed whence it was gone and at the same time explained why 

 they although larger had not been able to carry the victory in 

 the fight against the only surviving hungry and empty specimen 

 which did not have such great load in the stomach. The living 

 specimen was put. at liberty on an arena formed by four panes 

 of glass raised vertically and close together on a thicklayer of 

 sand on a sheet of iron. Small insects like flies were instantly 

 caught crushed and chewed up between the powerful jaws. Then 

 I put a middlesized ßutlius eupeus ^) on the arena. Galeodes 

 walked round with the palps stretched out and with their tips 

 just lifted above the ground. Finally with a rapid movement it 

 rushed forwards and caught the scorpion at the fourth (third 

 from the end) segment of postabdomen. That segment was 

 crushed, after which the jaws were moved distally to the fifth 

 segment and then to the poisonbladder, which was crushed and 

 cut. When this was done the jaws were again moved in the 

 opposite direction' towards the body of the scorpion. The seg- 

 ments of the prseabdomen were crushed, chewed and squeezed out, 

 so that only the outer chitinous integument remained and that 

 also was torn. While doing this the jaws of the Solpuga not only 

 chewed with vertical movements of the forceps, but also worked 

 with alternating movements forwards and backwards in the 

 horizontal plan. When the »Falanga» had reached the prseabdomen 

 it bit a large hole through the integument and worked its jaws 

 into the interiör, chewing and devouring. During the whole time 

 the scorpion wriggled and fought against its foe as härd as it 

 could, pinching it with its chelse, but in vain. When the jaws 

 of the Galeodes had penetrated into the praeabdomen of the 

 Buthus, the latter after a while ceased to defend itself. But it 

 was neither lame nor poisoned, so that it still moved quite lively,
