 series below lateral line. Dorsal 11-12, 39-42; anal 41-43. Pectoral with 16 rays, 

 extending to above origin of anal, length ij to if in that of head. Pelvic extending 

 about f of the distance from its base to the vent, length z\ to z\ in that of head ; insertion 

 of pelvic very little nearer to origin of anal than to tip of lower jaw.

 about twice as long as eye, diameter of which is 4I to 5I in length of head; interorbital 

 width about 4. Maxillary extending to below middle of eye, length less than h that of 

 head. 15 to 18 gill-rakers on lower part of anterior arch, no to 115 scales in a longi- 

 tudinal series below lateral line. Dorsal n, 36-40; anal 37-39. Pectoral with 15 or 



16 rays, extending to beyond origin of anal, length ij to if in that of head. Pelvic 

 extending f to f of the distance from its base to the vent, length 2 to z\ in that of head ; 

 insertion of pelvic nearer to origin of anal than to tip of lower jaw. 



Hab. Coasts of Chile and Peru, perhaps extending northwards to the Gulf of Panama. 

 Described from 4 specimens, 360-485 mm. in total length. 



This species is very similar to M. capensis, but has a rather smaller head and mouth, 

 rather more gill-rakers, larger scales, and shorter pelvic fins.
