mir als kolotili bezeichnet wurden" (p. 297). Likewise Dr. Bleeker 

 mentions having met with our common earthworms in different pla- 

 ces of the Malay Archipelago. Among the numerous earthworms from 

 this region however, examined by myself, I hitherto have not found 

 a single example referable to our indigenous genera Lumbricus and 

 Allolobophora. In view of the active commercial intercourse between 

 Europe and the Malay Archipelago , this is a rather curious fact , for 

 we know that Lumbricus-s^ecies occur in S. America and Australia, 

 though they belong without doubt to the fauna of the Palsearctic and 

 Nearctic regions. 



In the following list are enumerated the species of earthworms , 

 hitherto found in the Malay Archipelago (those collected by Prof. Weber 

 are indicated by an asterisc) :
