1897.] FEESHWATBE FISHES OF CELEBES. 427 



ological fauna of Celebes has been most abl}^ dealt with, three years 

 ago, by Prof. Max Weber \ Only about 80 specimens of Fresh- 

 water rishes were collected, which are referable to 14 species, 

 4 being described as new. The locahties are the same as enume- 

 rated in my previous paper, with the exception of the Lolak River, 

 which runs a little to the west of the Dumoga Eiver, in the 

 kingdom of Bolang Mongondo, and Lake Lahendang iu Mina- 

 hassa.
