 Teneriffe ; Australia; New Zealand. 



I follow Rosa (15) in the above synonymy; adding A. hercynius. No doubt 

 s^eral of the doubtful species mentioned on a previous page (p. 694) might also be 

 aidded on equally good grounds as those shown by Rosa for including Kinbebg's 

 'Lumhricus novae-hollandiae.' 



The anatomy of this species has been studied by myself. But my results, which 

 were based upon the examination of a specimen from Teneriffe, are not in all points 

 in accord with those of other observers.
