 less than half the length of the body ; first and second joints short ; 

 third very long; fourth and two following joints moderately long : 

 eyes dark brown, very small, as is usual in subterranean species : 

 mouth with a brown lip, reaching far beyond the base of the hind 

 legs : oviduct short, with a brown tip : legs moderately long; fore- 

 feet and middle-feet black, short and curved ; hind-feet long, pale 

 and straight, their tips brown : the young ones are more narrow and 

 linear. The hind-legs have great freedom of movement, and it often
