1 Zygoneeles atrilatus, Zygonectes inurus, Haplochilua mslanops, Gambusia holbrooki, and 

 probably Gambusia arlingtonia also, are identical with Gambusia patruelis. 



2 Gambusia humilis Gunth.eT=iZygon€ct€8 brachypterus Cope, seems to be distinct from 

 Gambusia patrHelis. It abounds in the streams of Texas, and may be known at once 

 from G. patruelis by the absence of the black suborbital spot. 



•* Doubtful species, unknown to me. 



* Mollienesia lineolata is identical with M. latipinna. 



*The name Heterandria Agassiz, Amer. Journ. Sci. Arts., 1853, as now restricted is 

 identical with Girardinus, and must supersede this later name. The type is Heterandria 

 formosa Agassiz. As originally defined, both Gambusia and Girardinus were included 

 in Heterandria. See Jordan «fe Meek, Proc. U. S. Nat. Mus., 1884, 236. 



^Heterandria ommata Jordan, Proc. U. S. Nat. Mus., 1884, 323. Indian R., Florida. 



''This species should stand as Eaox vermiculaius, instead of Esox salmoneus or Esox 

 umbrosus. 



To the synonymy add : 



{Esox vermiculaius, Esox Uneatus, and ? Esox lugubrosus Le Sueur MSS. in Cuv. & Val., 

 XVIII, 333, 335, 338, 1846.)
