of earthworms, should obviously include the specific names giveu 

 above, which really only differ in size. Its characters, save those 

 of size, are by no means salient, and with difficulty can it be 

 separated from the next species. I also place here A, wUhyi, which 

 cannot be, as is suggested by Michaelsen, a synonym of capensis 

 since the latter has a terminal bursa. I am rather inclined to 

 think that opercidata (see p. 618) should come here.

 Spermiducal gland not very large. Diverticulum longer than

Dr. Michaelsen has indicated the close likeness which all the 

 forms here brought together exhibit. He, however, would allow 

 three species, viz., A. halmaherce, A. jampeanus, A. purpnreus. The 

 reasons for uniting all must now be dealt with. A. halmahercx.
