146 Schiodte's Specimen 



I afterwards found a second in a similar locality there, and a 

 third in the Magdalena cave ; the two latter nearly twenty feet 

 ahove the floor. These were the only specimens which I met 

 with in a living state ; but we may conclude from the many re- 

 mains of dead specimens, found in the breaks of the columns, 

 that the animal is common at other seasons ; for its skin may 

 long be preserved in the cool air of the caves, although it is at 

 length covered by the calcareous deposit. The animal moves 

 slowly and cautiously, supported on its long legs, as if on stilts ; it 

 stands still the instant that light, or rather the sound of approach, 

 reaches it, when it crouches down and remains immoveable, with 

 erect antennae and stretched out legs, unless it is touched. Many 

 of the remains were dispersed in such a manner, that there can be 

 no doubt of the animal being killed and devoured by animals of 

 prey, which, it maybe easily conjectured, are the two Arachnidans 

 subsequently described, which, it will be seen, are well fitted for 

 hunting.
