This species differs from L. seiiiistriatits Kaup in having a shorter snout,

 number. It is apparently also a smaller species, being adult at half the recorded 

 size of L. seiiiistriatus. The type of the latter is stated by Gunther to be from 

 "South Australia," for which we would read Southern Australia, the known 

 habitat being Victoria and Tasmania,
