Papillae in neighbourhood of male pores, and also paired on some of segments which contain spermathecae. Sperm-sacs often with median process. Spermiducal gland in several segments, with not long, curved or straight duct. Spermathecae (occasionally two pairs only) with diverticulum of about same length. Hab. Borneo, China, Mauritius, Hawaii, Bermudas, Barbados, South America, Teneriffe. In my account of the earthworms of Hawaii, published in the 1 Fauna Hawaiiensis,' I have stated in full m y reasons for uniting the five reputed species enumerated in the above synonymy. I condense from that a sufficient abstract for m y present purpose. A. hawayanus does not, as I have suggested, differ from A. bermudensis in the absence of seta? upou the clitellum; but this occasionally occurs in hawayanus. Both of these forms may have anterior papillae on the viith segment near to the spermathecal pores. They are by no means always present in either. The twro forms have sometimes simple caeca without the series of rounded processes inferiorly, which have been mentioned as a characteristic. The form hawayanus must be also united with barbadensis ; the |
