The main characters distinguishing this species from A. pro- 
pugnatoris are the large tubercles on the upper side of disk and 
arms, the more coarsely granulated under side of the arms and the 
granules covering the sides of the mouth angles. Further the dark 
patches on disk and arms, so characteristic of AÅ. propugnatoris 
are not found in the present species.
