12 FISHES OP ARKANSAS. 



20. Zygonectes notatus Eafinesciue. 



21. Fundulus catenatus Stoicr. 



22. Esox vermiculatus Le Sueur. 



In ponds and cut offs tributary to the Saline. 



23. Labidesthes sicciilus Cope. 



24. Roccus chrysops Eafinesque. 



25. Micropterus salnioides Lac^iiede. 



26. Micropterus dolomiei Lacdpede. 



The two species of Black Bass are about equally abuudaut la th 

 Washita aud Saline. 



27. Leponiis cyanellus Rafiuesque. 



28. Leponiis humilis Girard. 



29. Lepomis megalotis Rafiuesque. 



30. Leponiis pallidus Mitchill. 



31. Ammocrypta vivax Hay. (3()4]4, 3G444.) 



32. Crystallaria asprella Jordan. (3G41'2.) 



Three specimens taken in the Washita Eiver, the largest about 

 inches in length. 



This sj.iecies differs quite strongly from the Ammocryptie in havinj 

 the premaxillaiies non -protractile, in the much greater development o 

 the vertical fins, and in the less hyaline structure of the body, whicl 

 is also more closely and firmly scaled. In all these regards it rei)resent 

 a transition from Ammocru'pta toward Hadropterus. 



The descri[)tion in our Synopsis Fish. N. A., p. 490, is badly vitiate( 

 by the count of the tin-rays having been taken from a young examph 

 supposed to be the same as the type, but really belonging to Ammocrypti 

 vivax. D. XIV, 13 ; A. 1, 12. Scales, 7-83-x. The statement made b; 

 Mr. Worthen, the original discoverer of the species, that in life it ''pre 

 sents all the colors of the rainbow," is erroneous. The life coloratioi 

 is substantially as described in the Synopsis, there being noredorbkn 

 markings. 



33. Boleosoma camiiruni Forbes. (3()4'20, 36441.) 

 Abundant in the small pools and cut-offs. 



34. Cottogaster copelandi Jordan. (36416, 36471.) 

 Yery abundant. 



35. Cottogaster uranidea Jordan «.t Gilbert. (36413.) 



Five or six specimens taken in shallow rapid water in the Washita, 



36. Etheostoma histrio Jordan & Gilbert. (36409, 36448.) 



Not rare in the current. The frenuni of the upper jaw in this species 

 is \-ery narrow, so that the premaxillaries are almost protractile. The 

 skull is narrow aud high across the parietal region, as in E. ecaruleum,
