1102 NOTES FROM THE AUSTRALIAN MUSEUM. 



These little fishes appear to be plentiful in the Parramatta 

 River, numbers being obtainable any morning in the fish market 

 among prawns from that locality, along with the recently-recorded 

 Ainbassis gymnocephalus. Out of numerous specimens examined 

 during the last two months the largest measured but 2 -85 inches, 

 and none were under 2 inches. A.U the examples examined 

 during the latter half of October and the earlier half of 

 November were spawning, the milt or ova running freely from 

 them on the slightest pressure. The scales of this species must be 

 very deciduous, since notwithstanding the numbers which we have 

 handled, we have failed so far to detect a single scale on any 

 specimen ; and it is also noteworthy that the palatine bones are 

 unfurnished with teeth, contrary to the rule holding good for 

 other members of the genus.
