204 NEST OF ROCKLING. 



It closely resembles it, but has two additional barbules 

 on the upper lip. The general colour is dark brown, 

 sometimes with a bronze lustre, the belly whitish, and 

 generally it is without spots. 



Mr. Couch gives an interesting account of the nest 

 made by this fish : *' The nest is invariably formed of 

 the common coralline [CorralHna officinalis), put together 

 without skill or arrangement, thrust into some cavity 

 of a rock close to the low- water mark, and the materials 

 are maintained there by no other bond than that of 

 compression. This coralline is sometimes not found 

 without one to two hundred feet of the selected spot ; it 

 must be gradually collected and brought with a great 

 degree of perseverance. The eggs are not contained in 

 the cavity like those of the stickleback, but scattered 

 through the mass of coralline." I am very anxious to 

 get one of these nests. 



The Fom'-bearded Eockling (Gadus cimhrius, Motella 

 cimhria) is perfectly distinct from the two others, having 

 three barbules on the upper lip, and another on the 

 chin, and a long projecting filament in front of the first 

 dorsal ray, which has a striking appearance. Its length 

 is nine or ten inches, and it is found in the Fh'th of 

 Forth and the neighbourhood.
