Borlasia octocidata, Johnst. McIntosh, in a paper on the structure of the 
British Nemerteans (as yet only published in abstract), has described the re- 
production of the proboscis, the growth of an amputated anterior end (often 
consisting of little more than a head) into a perfect body and tail ; and the 
remarkable tenacity of life enjoyed by many of the dissevered fragments of 
the body, which survive for months, and elaborate the generative elements 
in their interior j but since these remarks were made, it has been found that 
in B. octoculata each of the numerous fragments into which its lengthened 
and fragile body breaks becomes a perfect animal.
