In my account of the earthworms of Hawaii, published in the 

 ' Fauna Hawaiiensis,' I have stated in full my reasons for uniting 

 the five reputed species enumerated in the above synonymy. 

 I condense from that a sufficient abstract for my present purpose. 

 A. hawayanus does not, as I have suggested, differ from A. ber- 

 mudensis in the absence of setae upon the clitellum ; but this 

 occasionally occurs in hawayanus. Both of these forms may have 

 anterior papillse on the viith segment near to the spermathecal 

 pores. They are by no means always present in either. The two 

 forms have sometimes simple cseca without the series of rounded 

 processes inferiorly, which have been mentioned as a characteristic. 



The form hawayanus must be also united with barbadensis ; the
