4 FISHES OF ARKANSAS. 



Scales large, with well-defined edges ; about 13 before dorsal. Later 

 liue decurved. 



Insertion of dorsal very slightly behind ventrals, slightly nearer t: 

 of snout than base of caudal. Dorsal fin rather high and poiutec 

 other fins moderate. 



Color greenish, sides with a silvery shade, above some plumbeou 

 Some dusky on sides of snout and on opercle. Dusky points along tl 

 pores of the lateral line, and forming an obscure blotch at base of ca 

 dal. Fins plain, with some dusky at base. Scales above, with dusL 

 edges, their outlines therefore well defined. 



This species is common with the two preceding. It is not very di 

 ferent from the young of N. zonatus. Compared with the latter, it seeu 

 to be ra.ther more robust, with larger scales, the boundaries of whic 

 are more easily traced. There are also some slight differences in colo 

 We regard it, however, as without much doubt a distinct s])ecies. 



12. Notropis megalops Eafinesque. 

 Common. 



13. Notropis micropteryx Cope.

 short, 2 in head, their tips reaching slightly more than h distance 1

14. Hybopsis amblops KaGiiosque. 



Very common. Not evidently different from Indiana specimens. 



15. Hybopsis dissimilis Kirtlaud. 

 Common. Lat. 1. 40. 



16. Hybopsis kentuckiensis Rafinesque. 



(Litxilus leniiickitiisis Rnf. = Se7noHhis li{/uttatiis Kirtlaud.) 



17. Phoxiniis neogceus Cope. 



A single specimen, not agreeing very well with Cope's description 

 rather better with that of Jordan & Gilbert (Synopsis. :"4.".), but jn-ol
