FOUB-BEARDED BOCKLING, 
exactly in front. In this respect its structure may be easily 
distinguished from that irregular formation which has been 
referred to, and which may not occur again in the Five-bearded 
Rockling. A farther distinction is noticed in the much longer 
extension of the thread, or process, which stands up before 
the ciliated membrane behind the head. The ventral fins are 
shorter than in the other species, and the head somewhat longer. 
It is probable that its colours vary in some degree, according 
to the nature of the ground; but usually, while the back and 
sides are dusky and reddish, there is a whitish border to the 
dark brown dorsal and anal fins. It has been known to measure 
fifteen inches in length.
