Collection of Fish 
gaily coloured, and one of them indeed brilliantly striped, 
have only five rays in the branchiostegous membrane. 
They are all true Lahri, but the scales which protect their 
opercula , though in fact much larger than those of Labrus 
hergylta, are so deeply imbedded in mucous skin, that in 
a recent state these fish might pass for examples of the 
genus Tautoga, which they further resemble in possessinga 
tolerably regularinner row of minute teeth. They are with¬ 
out scales on the interoperculum, and the small scales on 
their cheeks being variously distributed, furnish specific 
characters. All four have canine teeth at the corners of 
the mouth, and, contrary to the prevailing character of 
the Lahri , the soft rays of the dorsal exceed the spinous 
ones in number, resembling in this respect the Labrus 
pcecilopleura of New Zealand.

Then follows the description of a small Odax, known 
at Port Arthur by the name of Kelp Fish. It agrees 
with Odax semifasciatus of the Histoire des Poissons in 
many of its details, but on a minute comparison with the 
description of that species it appears to be distinct.
