Ap\rt from its much smaller size and the obsolete punctuation 

 on both surfaces, this species differs from A. dregei \\\ its much 

 straightei-. slightly curved rostrum. The rostiul tooth is also 

 much smaller ai\d does not curve foi-wards in the © ; while the 

 rostrum of the $ entii-ely lacks the two inferioi- tubercles which 

 are present in dregei.
