 slightly enlarged. 



Barbel stout, three-fourths as long as the eye. 



Scales closely covered with tiny capillary spinelets which are deciduous and 

 do not project beyond the edge of the scale. 



[Five rows of scales between the last ray of the first dorsal fin and the 

 lateral line, as in M. investigatoris.] 



Outer ventral ray as long as the head behind the anterior nostril. 



Vent far behind the tip of the mass of the ventral fins.
