characters little differentiated. However, Lethrinus mahsena usually 

 has a more abrupt front profile to the head, so that the jaws are less

 protruded anteriorly in comparison. Great variation occurs in the 

 eyes of both species. 



Lethrinus abhreviatus is based on a drawing 188 mm long. Back 

 elevated. Depth nearly % length. Blue-green, crossed by 10 to 12 

 regular brown bands.
