Dr. Max Weber's collection. But only those who are familiar with the 

 vast number of species of millipedes that abound in the tropics, with 

 the narrowness of the range of each , with the worthlessness of most 

 of the existing descriptions and with the dearth of good figures, will 

 be able to understand the necessity for describing such a host of new 

 species as are established in the following pages. 



That all the species, however, will ultimately prove to be new, is 

 what I scarcely expect. Nevertheless I shall feel well satisfied if the 

 descriptions and figures that are here published are sufficiently exact 

 to enable others to discover which of the species have been previously 

 described by my predecessors. 



While describing Dr. Max Weber's Celebes species, I have taken 

 the opportunity of adding diagnoses of two interesting forms that 

 were brought from this island by Dr. S. J. Hickson.
