front of dorsals. D. IX-14; A. I, 9. Scales 4-50-7. Oliva- 

 ceous with blotches and zig-zag markings on sides ; fins with 

 fine zig-zag lines. Length Sj4 inches. 



Eastern United States, very common; often in tidal creeks, 

 where the water is impure but not salty. In the aquarium

 Fan-tailed Darter. 

 Body long and low; head pointed, mouth with both jaws

 olive with darker bars or streaks. D. and C. with zig-zag bars ; 

 caudal fan shaped. D. VIII-12; A. II, 8. Scales 7-50-7.
