NOTES ON MILLIPEDES. 31 



In Bangkok I found this species very common, and also 

 caught specimens at Ayuthia, in the Dong Phya Phai, at Kabin, 

 at Chantaboon and on the island of Ko-si-chang. 



When suddenly found under a stone they seem to seek 

 safety rather in remaining perfectly motionless than in taking 

 instant flight. 



I have noticed them eating crickets and moths, possibly they 

 will eat any insects they can catch and overpower, but I have 

 watched them encounter and leave unmolested, though hungry, 

 a beetle (Carabida>) and a small green bug. On several occa- 

 sions I have placed these scorpions with whip-scorpions 

 {Thelyponns sckimJcewitchii) and with large spiders (Heterapoda 

 venatorea) to see if they would try to tackle other Arachnida, 

 but I found the three sorts all left one another alone. I 

 have not observed them even attempt to feed on insects they 

 have not killed themselves, nor to pay any attention to fruit. I 

 do not know if they ever drink, I find an entry in my diary for 

 the 26th December, 1897 : — U A. mueronatus caught on the 

 15th of this month is still alive and well. It has had no water 

 all the time." Unfortunately I find no note as to the further 

 career of this scorpion, or how long it lived in captivity. When 

 walking this species ofter has the combs extended and pointed 

 forward. It seems quite blind (at any rate in a full light), it 

 runs swiftly with both chela? extended, but if an upright thing, 

 such as a stick which the chela? pass on each side of without 

 touching, is met with, the scorpion runs right into it and is 

 pulled up short ; just as a man feeling for the door in the dark 

 with outstretched arms may, if the door be standing open, 

 suddenly find himself hit in the face by it ; but on the other 

 hand I have seen a scorpion pursue a fluttering insect, but this 

 may have been by sound (or smell ?). 



The following extract from my diary of the 15th December 

 1897 will give some idea of how these animals feed. 



A. mueronatus ; in the evening I watched it sitting quite 

 still, body very flat on the ground, chela? extended, tail curved 

 over back with the point of the sting carefully protected in the 

 usual manner ; a small moth settled near it, the scorpion imme- 

 diately seized the moth in both chela? and quick as lightning 

 brought its tail over its head, stung the moth and recovered
