on fhe centre of the lower jaAV ; the spiny dorsal, the caudal, the 
pectorals, and vcntrals are yellow ; the soft dorsal and the anal 
are obscure, sometimes black with a blue tinge ; the base of the 
pectoral is black. These colours are subject to some variation. 
When dry, the body presents the same feeble longitudinal ridges 
I have mentioned in another sort. 
Seen several specimens, which were found in Eebruary ; the 
longest measured 17 inches. The fishmongers say that this sort 
is very good for the table. 
This may be the Lahrichthi/s JSpliipjnum of Gunther (“ Ann 
and Mag. of Kat. History, 1863,” p. 116), hut it is certainly not 
the sort described by Cuvier under that name, and which is said 
to come from Hew Zealand. 
Nota. — The three sorts of Ldbriclithys I here describe can 
he distinguished in the following way : — 
(o.) Two series of scales on the cheeks; no transverse bands. — 
Hleekeri. 
(h.) More than two; transverse bands on the body; 
ground colour, green. — Bicliardsonii. 
ground colour, reddish. — Vestita 
I believe that the dentition is subject to great variations with 
age, and that the presence of one or two teeth at the angle of the 
mouth is sometimes due to the same cause. 
ODAX. 
Genus established by Cuvier aird Valenciennes on several 
sorts which have the teeth solved together like the beak of a 
parrot, but differs from Scams, which has also this character, by 
the scales of their body being small.
