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 Michardsonia 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 Bicliardsonia becomes disposable.
