ON THE OCCURRENCE OF CROCODILUS POROSUS 



FAR ABOVE THE TIDEWAY IN A 



SUMATRAN RIVER 



Dr. EUG. DUBOIS. 



(July 1896). 



In the volume of the » Fauna of British India" edited 

 by W. F. Blanford , containing the description of the 

 Reptilia and Batrachia by G. A. Boulenger, it is stated, 

 p. 4, that it is not certain that Crocodilus porosus Schneid. 

 is found far above the tideway in rivers. 



It may therefore be of some interest to state that I found 

 (1889) an individual of this species (the skull of which 

 is now in the Leyden Museum) living in the river Sinamar 

 near Boea in the Highlands of Padang, Sumatra. The 

 Sinamar is a branch of the Kuantan , which latter has its 

 mouth on the east coast of the island, whilst Boea is 

 situated much nearer the west coast from which it is, however, 

 separated by several ranges of high hills; the straight dis- 

 tance between Boea and the east coast is about 300 km. 

 Between that place and the lower course of the Kuantan 

 the Sinamar breaks through another range of hills giving 

 over a long extent cause to rapids, which make navigation 

 over some of those stretches quite impossible, even for the 

 smallest praws.
