19 GADID.E. 



the head, back, and sides, uniform dark brown ; lower part of 

 the sides lighter brown ; under surface of the lower jaw, the 

 ventral fins, and the belly to the vent, white ; the other fins 

 dusky brown ; the course of the lateral line distinctly marked 

 by a series of short, slender white streaks, as shown in the 

 wood-engraving. 



I have been favoured by Dr. Richardson with the follow- 

 ing description of the appearance of a fine example of this 

 species : General colour of the body pale bronze, approach- 

 ing to that of jewellers'* gold, with streaks of purer gold co- 

 lour above the lateral line in the direction of the ribs. The 

 upper parts of the head and the gill-covers yellowish brown, 

 blended on the cheeks with the bronze. The fins are also of 

 a brownish orange or bronze colour, but without the metallic 

 lustre, and their margins are blood red ; the red tinge is more 

 general on the pectorals ; the irides silvery, the pupils blu- 

 ish black. 



Both the species last described have been called mustela 

 by different authors. Linnaeus attached this term to the 

 species with five barbules : Cuvier, in the Regne Animal, 

 identifies the Three-Bearded Rockling with this same word. 

 As the number of barbules appear to be constant in each, a 

 reference to the number in the specific name is, perhaps, the 

 least objectionable. Linnaeus, and other authors to the 

 present time, continue, as before stated, to consider the north- 

 ern species with four barbules as distinct from both.
