Fig. 132 and Plate XXVII, figs. 2 and 3. 
Five barbels: one at each of the anterior nostrils, a pair at the tip of the snout , and one under the chin. Length 
of the head in adult specimens 19 — 46 ,1 / 2 % °f that °f the body a . Longitudinal diameter of the eye in full-grown 
specimens less than 30 % of the postorbital length of the head , this length being greater than either the distance 
between the tip of the snout and the hind extremity of the maxillary bones or the length of the lower jaw, which 
is less than half that of the head. Least depth of the tail more than 40 but less than 46 % of the depth of the 
body at the beginning of the anal fin.

According to Pennant and Fleming 6 , it is true, the 
Five-Bearded Roclding attains a length of about 4V 2 
dm. (18 in.); but specimens of this size are otherwise 
unknown. The largest specimens in the Royal Museum 
are Ffi dm. long, and Malm never found the length of 
this species to exceed 28 cm. on the coast of Bohuslan. 
The head is comparatively small, with small eyes 
and fiat but comparatively broad interorbital space. 
The tip of the snout is naked for a greater distance 
than in the Three-Bearded Rockling, the boundary of 
the scales running between the posterior nostrils or 
even in a line with the front part of the eyes. The 
proportion may be 2 2 1 / 2 %.
