Habits. These Arachnida are remarkable for their amazing agility. 

 Though principally desert forms, they are also met with in 

 forests, at least in India. They are nocturnal and strictly car- 

 nivorous. Some of the species at all events dig holes in the 

 ground, and the females at the breeding-season live in burrows for 

 the protection of themselves and their young. The latter are born 

 in the egg-stage.

 of the Union to the Andean chain in Chili and the Argentine 

 Eepublic. 



The families and subfamilies represented in the fauna of British

Claws of legs, in the adult, with several rows of hairs upon the
