on the centre of the lower jaw ; the spiny dorsal, the caudal, the 

 pectorals, and ventrals 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 February ; the 

 longest measured 17 inches. The fishmongers say that this sort 

 is very good for the table. 



This may be the Labrichthys Eiihippiiim of Gunther (" Ann 

 and Mag. of Nat. History, 1863," p. 116), but it is certainly not 

 the sort described by Cuvier under that name, and which is said 

 to come from New Zealand. 



Nota. — The three sorts of Labrichthys I here describe can 

 be distinguished in the following way : — 



(a.) Two series of scales on the cheeks; no transverse bands. — 

 BleeTceri. 



(b.) More than two ; transverse bands on the body ; 

 ground colour, green. — Richardsonii. 



ground colour, reddish. — Yestita 



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. 



Grenus established by Cuvier and Valenciennes on several 

 sorts which have the teeth solved together like the beak of a 

 parrot, but differs from Scar us, which has also this character, by 

 the scales of their body being small.
