My specimens from Canton and Hull Islands are referred to this 

 species with considerable uncertainty, but until the genus Atherina is 

 carefully reviewed it is impossible to distinguish them with any degree 

 of surety. The Canton Island specimens at 55 mm. contained eggs 

 almost ready for spawning.
