 such a way that the movable finger is inside and opens 

 laterally, not vertically ; it has a strong, long spine on its 

 base. The palm is swollen and has outside granulations 

 and some hairs; the fingers are equally granular and 

 hairy ; the arm and forearm are rough and hairy. The 

 small pincer is very frail. The legs of the second and third 

 pair are laterally compressed, and terminate in styliform 

 fingers, and have some hairs ; they are unarmed. The 

 ocular scales are rounded in front, and toothed on the 

 edges. The antennal flagellum is thin, moderately 

 hairy, and scarcely exceeds the base of the larger 

 hand.
