Folliculina holtoni (S. Kent), 319 



detached from the same, and which owing to an exceptional faculty 

 of regeneration had soon acquired the normal appearance of 

 Infusoria (some of them, indeed, provided with a portion at least 

 of the former nucleus, woukl perhaps develop into a normal 

 Stentor) ; and now these conchisions would seem to be confirmed 

 by the facts acquired about Folliculina. If we keep in mind the 

 remarkable faculties of this latter organism, which entirely re- 

 absorbs its exterior structure to grow into a quite different being, 

 and then regenerates again into a new dissimilar type ; if at the 

 same time we take into account the very near relation existing 

 between Folliculina and Stentor — we are undoubtedly entitled to 

 consider Biitschli's Lieherkuhnina as having no objective existence 

 as a separate family.
