S dark greeu; sides with 10 to 14 narrow, pearly bands, slightly ob- 

 lique, and mostly narrower than the interspaces 5 a diffuse dnsky blotch

Page 340. Zygonectes atrilatus should probably be suppressed. It 

 appears to be based on females of Gambusia patruelis.

The known specimens of this species are from Cache Eiver, in South- 

 ern Illinois. For the synonymy in the text substitute —

 and Z. melanops Hay are apparently Gambusia ])airuchs.)
