 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 1!) — Kl^j^ ^ 'f that of the body". Longitudinal diameter of the ege in full-grown 

 specimens less than SO % 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 bnnes or tlie lengtJi. of the loicer jaa\ u-hich 

 is less than half that of the head. Least depth of the tall more than 40 but less than 4fJ % of tlie depth of the 



body at the beginning of the anal fn.

According to Pennant and Fleming", it is true, tlie 

 Five-I3earded Rockling attains a length of about 4^4 

 dm. (18 in.); but specimens of this size are otherwise 

 urlkno^vn. The largest specimens in the Roj'al Museum 

 are 2\i., dm. long, and Malm never found the length of 

 this species to exceed 28 cm. on the coast of Bohuslau. 



The head is comparatively small, with small eyes 

 and flat Imt comparatively broad interorbital space. 

 The tip of the snout is naked for a greater distance 

 than in tiie Three-Bearded Rockling, the boundary of 

 the scales running between the posterior nostril.s or 

 even in a line with the front part of the eyes. The 



" In yonng speeiniens, even after the C'onchia-siaga, this proportion may be 22',., °e. 



' Sometimes 55, according to Day.
