or Rhi/nchodemus and Bipalium witli regard to the form of 

 the aiiterioi- extremity, and, having carefully examined 

 specimens of these three genera both alive and in s])irits, I 

 have no hesitation in saying that the remarkable develop- 

 ment of the head in Bipalium is a most marked and 

 important character and of great value for purposes of 

 classification. 



Professor Spencer thinks that Bipalium keivense was 

 probabl}' introduced by the agency of man to the locality 

 where he found it, as has now been the case in so many 

 places. Possibly the original home of this remarkable worm 

 will ever remain a mystery. Within recent years it has 

 made its appearance in large numbers in the neighbourhood 

 of Sydney, as described in a very interesting pa])er" by Mi'. 

 Fletcher, who has also recorded tlie si)ecies from Victoria and 

 Samoa. I am not aware that it has hitherto been recorded 

 from Queensland.
