 Barred Killifish, Fundulus diaphanus. Fig. 48, *vhich inhabits brackish 

 water. Both thrive in the aquarium. The Barred form is marked with 

 steel-blue and silvery-white bars, and has a peculiar metallic lustre. 1 1 is 

 entirely harmless and very lively in its habits. Its food should be a mixed
