The height of the body is 4^-4| in the total length ; the distance 

 between the eyes is one-half the length of the snout ; the barbels 

 reach slightly bej'ond the vertical from the angle of the praeoperculum. 

 A black band from the eye along the lateral line to below the anterior

The skeleton differs very distinctly from that of Mullus and of 

 Mulloides JlavoUneatus. The maxillary is much narrower at the 

 base than at the extremity ; the posterior process of the intermaxillary 

 is very short. The frontal bones are concave between the orbits, 

 and there is a longitudinal crest along their meeting margins, ex- 

 tending nearly to the anterior end of the bones and not continued 

 into the occipital crest, which is rather higher than the lateral ones. 

 The angle of the praeoperculum is as much rounded as in M. harhatus ; 

 the basal portion of the brain-capsule is neither compressed nor 

 rounded. The length of the abdominal portion of the vertebral 

 column is to that of the caudal as 1 : 1-7.

The space between the eyes is somewhat sinuous. The barbels
