 an interval between each of them, the first smallest, the third 

 largest ; two minute teeth below ; inner surface denticulate ; 

 third joint cylindrical, without tooth * ; fourth joint rather 

 short, with very long terminal spine ; chelge long, flattened 

 externally ; the fixed finger broad, compressed, and strongly
