Definition. Length, 50 mm.; number of segment*, 90. Clitallum, XXII, XXIII- -XXVII. 

 Tutjercula pnbertatu a continuous land, XXIII-XXFI. Dorsal pores commence IV/V. 

 Spermatfifcae in IX, X, opening to outside of seta IF. Hal. Europe; S. America; 

 Teneriffe ; Australia ; New Zealand. 



I follow ROSA (15) in the above synonymy; adding A. kercynius. No doubt 

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

 added on equally good grounds as those shown by ROSA for including KINBERQ'S 

 ' Lumbncus novae-hollandiue.' 



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.
