AbstractForaminiferal collections from Java and Borneo stored in the Netherlands National Museum of Geology and Mineralogy in Leiden enables to study the range of variation in Lepidocyclina ferreroi and L. multilobata. Taken separately many features considered typical of L. multilobata and L. ferreroi are insufficient to identify the specimens. When typically developed both species are highly characteristic and easily distinguished. Transitional forms however cannot be classified with certainty. Possibly L. multilobata has evolved from L. ferreroi but too little is known about the ages of the two species, especially of L. multilobata. L. crucifera is probably a form of L. ferreroi with four rays distinguished by the development of more than one tubercle on each ray. A questionable occurrence of L. multilobata in Madagascar is discussed.
