The major diameter of the eye is 4- to 4- in the length of the head and 

 equal to the width of the interorbital space. 



Mouth rather large, the upper jaw, which is as long as the snout phis half 

 tlie eye, extending behind the middle of the eye. 



Outer row of teeth in the upper jaw considerably enlarged, in the lower jaw 

 slightly enlarged. 



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



Scales closely covered with tiny cajiillary 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. ii//vesfigatoris.~\ 



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