Nota. — Since writing the above, I have obtained a second 

 specimen of this fish ; it is larger, and measures near 33 inches. 

 It was taken in April, at Queenscliff. The three first short 

 spines of the dorsal have membranes, which connect them. 



The name of Bichardsonia has already been given by Mr. 

 Steindachner to a genus of fishes, which Mr. Grill had previously 

 called Betropinna, and this name being, of course, adopted, the one 

 of Bichardsonia becomes disposable.
