The suborbital crest is strongly salient and serrated and terminates acutely 

 at the preopercular angle. The posterior half of the head is longitudinally 

 traversed on each side by two strongly serrated ridges, one extends from the 

 interorbital space to the occiput, the other from the supra-orbital ridge to the 

 shoulder. 



Nostrils situated immediately in front of the eye ; the posterior is very 

 large. 



The mouth is a small, completely inferior, crescentic orifice ; its front limit 

 is in the vertical through the anterior nostril, and the maxilla reaches a little 

 behind the vertical through the middle of the eye. Villiform teeth in bands in 

 the jaws, the outer row in the upper jaw slightly enlarged. Barbel slender, less 

 than half the eye in length. 



Gill-rakers in the form of tubercles. 



Scales of the head with about 3, scales of the body with about 5, thin salient 

 slightly-divergent serrated crests. 6 or 6- series of scales between the last ray 

 of the first dorsal fin and the lateral line. 



The first spine of the first dorsal fin is very small, the second is smooth 

 throughout. The interval between the first and the very inconspicuous second 

 dorsal is hardly half the extent of the base of the first. Pectorals narrow and 

 pointed, their length slightly exceeds that of the postorbital portion of the head. 

 Ventrals with the outer ray prolonged well beyond the origin of the anal. 



Stomach large, siphonal ; very many long slender cjeca in a thick cluster 

 roimd the pylorus ; a thin-walled air-bladder. 



Colours in life : — Chocolate ; body and tail with numerous broad black cross 

 bands, which do not reach the mid-abdominal line. In spirit the colouration is 

 unchanged, but much lighter. 



The largest specimen is 7 inches long, 



Andaman Sea, 185, 188 to 220, and 405 fathoms.

 Differs from M. quadricristatus in the following particulars : — 



(1) the length of the snout is about two-fifths that of the head : 



(2) the suborbital crest ends bluntly, and the four crests on the nape are 

 low and inconspicuous :
