The Australian Oyster

Abstract

IN an abstract of my paper entitled “The Life History of the Australian Oyster, Ostrea commercialis”¹ an error was made in referring to the temperature of the water when oysters spawned at Port Macquarie, New South Wales. The temperature of 72°–76° F., given in the abstract as the spawning temperature, refers to that which prevailed for the most part during the six weeks prior to spawning. When the oysters actually spawned, the temperature of the water in contact with them was 68° F.; the water was two feet deep and the surface temperature was 70° F.
