 c s Dactylus of third legs with the ventral hook measuring one-eighth the 

 length of this joint or still less. 



y'j Dactylus of third legs with the ventral hook measuring one- 

 eighth the length of this joint, the dactylus one-fourth the

from one another by short interspaces Iocasta de Man
