30 ON LANDPLANARIANS. 



In the following lines I shall give an account on several 

 species of the Ley den Museum belonging to the genus 

 Bipalium, all of which were obtained from Java or the 

 neighbouring isles. Among them two species proved to be 

 new to science. 



1. B. marginatum K. & v. H. 



This species was first described and figured in a pre- 

 vious communication ^) from a specimen said to have been 

 captured in the forests of Bantam in West- Java (1822). 

 Afterwards (1888) it has been found at Buitenzorg by- 

 Prof. Max Weber, who brought home several specimens 

 from his journey. A specimen , now in the Leyden Museum, 

 has been collected in 1890 by Dr. J. F. van Bemmelen 

 in the same locality. 



2. B. javanum Loman. 



The area of distribution of this common species is 

 remarkably well defined and seems to be rather small. It 

 has been found in great abundance only in the dark forests 

 of the mountainous parts of West-Java and in those of the 

 isle of » Dwars in den weg" in the Sunda-strait , geologi- 

 cally belonging to West-Java. Neither on the volcanoes 

 of Middle-Java, nor on those of East-Java a single spe- 

 cimen could be taken. 



One specimen collected by myself in South- West-Java 

 in 1882. 



3. B. vittatum K. & v. H. 



This species ^) seems to inhabit the descents of the West- 

 Java mountains in the lower districts, f. i. Buitenzorg, 

 where the preceding species is very rare. I never met with 

 it in higher regions. 



Many specimens caught by Dr. J. F. v. Bemmelen in 1890.
