NOTE TO SECOND EDITION •> 



at our disposal. In studying the distribution of the different 

 species we have been greatly indebted to the collections made 

 by the Rev. W. Cran and also by Professor Raunkiaer in the 

 West Indies, by Dr. R. E. Fries in Sweden and Bolivia, by 

 Professor Penzig in Java, and by Mr. Hugo Bilgram in Penn- 

 sylvania. The observations of our friend Mr. Petch on the 

 Mycetozoa of Ceylon have been of great value, and our know- 

 ledge of those of Japan has been much increased by the un- 

 wearied labours and graphic correspondence of Mr. K. Minakata, 

 from whom we have received nearly three hundred specimens. 

 The numerous gatherings made by Dr. C. Torrend in Portugal 

 are the first examples of this group recorded from that country 

 and have been kindly sent us for inspection. Dr. Celakovsky 

 has presented us with a valuable collection of his Bohemian 

 gatherings ; we have also had the advantage of receiving 

 many Swiss specimens from our friend Professor Hans Schinz, 

 of Zurich, and, recently, from M. Meylan from the Jura 

 Mountains. There are many others whose names I have not 

 mentioned to whose contributions we have been greatly 

 indebted. 



I should like to repeat on my own account the acknow- 

 ledgment given above to Professor Farlow for his continued 

 assistance and sympathy, and to Mr. James Saunders for his 

 constant assiduity not only in reporting his own investiga- 

 tions but in arousing the interest of others in the subject. 



I cannot close without saying how invaluable it has been to 

 me to have the counsel and experience of my brother Mr. 

 J. J. Lister to rely on in continuing our father's work. 



The plates at the end of the volume are reproductions of 

 water-colour drawings made under the camera lucida by my 

 father and myself, and are here reduced to half the diameter 

 of the originals. 



G. LISTER.
