94 LIFE-HISTORY OF CEEATODIJS (NEOCERATODUS) FORSTERI. 



I believe mj-self that they can stay at the bottom for 

 days together ; I know that they resemble eels in being able 

 to exist buried dee]) in mud after a lagoon had dried up. 

 When a heavy thunderstorm has caused much mud to enter 

 the river suddenlj^ Ceratodns, like mullet, cat fish, and 

 perch, have died, but I have never seen an eel die from that 

 cause. 



I have had the opportunity of seeing the river in a 

 prolonged drought and find that, contrary to what I had 

 expected would have obtained in a large, deep lagoon * water- 

 weeds follow the receding water and uj) till the last the 

 general appearance of the lagoon is similar to its normal 

 state, that is to say, there are alwa3\s water-weeds with the 

 associated fauna — small fish, insects, shrimps, etc.
