(Plates 2, 3 and 4). 



As the reader will see from the head of this paper, the 

 collections are principally made in the interior of the island 

 and therefore almost entirely restricted to terrestrial and 

 freshwater forms. Seven new species have been obtained, 

 while many others are very interesting with regard to the 

 geographical distribution. 



The few marine specimens, all belonging to common 

 species, have been obtained by Dr. Hallier, the botanist 

 of the expedition, on the Coast of Sambas and the oppo- 

 site island Lemoekoetan. 



I have given in this paper a complete list of the species, 

 with description of the new ones. 



1) An ample explanation of the different localities where the zoological col- 

 lections have been obtained, will be given later on in the «Notes" by Dr. J. 

 Biittikofer in his paper on the ornithological collections of the expedition.
