The height of the body is 45-4| in the total length ; the distance

The skeleton differs very distinctly from that of Mullus and of 

 Mulloides flavolineatus. 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 orbitg, 

 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. barbatus ; 

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

 roimded. The length of the abdominal portion of the vertebral 

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