Mr. ] ac oh son ') on this subject. For the study of the development of the 

 new flora these remarks are of no importance. It should only be noted that 

 lacobson in 1908 observed no bats on Krakatao during the 3 nights he passed 

 there. Neither did he find earth-worms (which were found in 1919, see p. 221). 



In 1908 Mr. J a c o b s o n did not reach the older parts of the higher 

 ravines in which earth-worms may have been present. The investigation 

 in 1908 was altogether insufficient to warrant a statement as to the 

 non-occurrence of such small animals as are easily overlooked. 



Of the 5 appendices to the paper of Mr. Docters van Leeu- 

 wen I shall first discuss Appendix II giving a list of plants found 

 on and near the beach, hence containing oecologically very different 

 plants. This list contains 86 species, but omitting those not found on 

 the main island and reducing one as a synonym to another species 

 we arrive at a total of 67. These are the following, arranged after 

 the system of Christen sen (Ferns) and Engler and Prantl. 

 About each species not yet formerly found on Krakatao I have given 

 a few data on its distribution on Java and its means of reproduction. 

 About the distribution in South-Sumatra no sufficient data are extant. 



PLANTS FOUND ON AND NHAR THE BEACH. 



Schizophyllaceae. 



/ (86). -) Schizop/iyllum alncutn Sc/irotcr (=Sch. commune Fries). 

 Cosmopolitic fungus, living on decaying wood and such- 

 like substrata, spread throughout the East-Indian Achipelago. 

 The reproduction is effected by spores. 



No littoral plant. This fungus was found on bamboo-stems 

 on the beach. We are not told whether these had been 

 washed ashore or had been imported by Mr. H a n d I for the 

 construction of his buildings (See p. 196). Living bamboos 

 had as late as 1919 not yet been collected in the island. 



Polypodiaceae. 



2 (81). Nephrolepis biserrata Sc/iott. 



Terrestrial or epiphytical fern, rather common throughout 

 Java from the plains up to an altitude of + 1000 m. except 

 in regions where the east-monsoon is very strong. It grows
