In his review of the palaeozoology of Java, K. Martin could in 1919, record 49 foraminifera from tertiary strata of Java, on the strength of a critical study of the existant literature, and especially on the strength of his own studies and knowledge of the above mentioned fossils (Bibl. 49). In composing the following list of the Foraminifera I have only been able to perform such a critical study for a few families. For the greater part, however, I have had to restrict myself to recording the results obtained by others, and even therein I have been obliged to restrict myself.
