 indistinct. 



Major diameter of the eye about 4- in the length of the head. 



Outer row of teeth in upper jaw slightly enlarged. 



Barbel very inconspicuous, not a third as long as the eye. 



Scales with 12 to 17 rows of spinelets, the rows converging towards the 

 middle line of the scale, the last in each row projecting far beyond the edge of 

 the scale. 



[Five rows of scales between the last dorsal ray and the lateral line, as in 

 M. investigatoris]. 



Second spine of the first dorsal fin much prolonged, — 1- to 1^ times as long 

 as the head. 



Pectorals as long as the postorbital portion of the head. 



Outer ventral ray about as long as the head behind the middle of the eye. 



Vent behind the mass of the ventral fins.
