cur about Charleston, but no authentic instance of their being- 

 found in the region has come to the knowledge of the writer 

 of this paper. These are given in the following hypothetical 

 list 



Lepisosteus platostomus Rafinesque, Short-nosed Gar. 



Anguilla chrysypa Rafinesque, American Eel. 



Hiodon alosoides (Rafinesque), Northern Mooneye. 



Ictiobus cyprinella (Cuvier and Valienciennes), Red- 

 mouth Buffalo. 



Ictiobus urus (Agassiz). Mongrel Buffalo. 



Ictiobus bubalus (Rafinesque). Small-mouthed Buffalo. 



Moxostoma anisurum (Rafinesque), White-nosed Sucker. 



Phalcopharynx duquesnei (Le Sueur). 



Notropis heterodon (Cope), Black-chinned IMinnow. 



Notropis gilbert! Jordan and IMeek. 



Notropis jejunus (Forbes). 



Ictalurus furcatus (Le Sueur). Blue Cat. 



Ameiurus nebulosus (Le Sueur). 



Noturus flavus Rafinesque, Stonecat. 



Fundulus dispar (Agassiz). 



Lepomis mineatus Jordan. 



Eupomotis heros (Baird and Girard). 



Stizostedion vitreum (Mitchill). 



Hadropterus ouachitae (Jordan and Gilbert). 



Cottogaster shumardii (Girard). 



Crystallaria asperella (Jordan). 



Etheostoma zonale (Cope). Banded Darter. 



Etheostoma squamiceps Jordan. 



There are thirty-eight of the seventy species recorded 

 about Charleston that may be considered either common or 

 abundant. A list of these is given in the table on page^ 104-5. 



One of the most interesting features concerning the dis- 

 tribution of fish in the streams about Charleston is the dis- 

 similarity between the fish faunas of the Kaskaskia and the 

 Embarras systems in the region. There are five species in 

 the latter that are either absent or very scare in the former. 

 These are the stone-roller, Storer's chub, brindled stonecat, 

 green-sided darter, and the rainbow darter ; and then there are 

 six species, each forming quite a conspicuous part of the Kas- 

 kaskia fish fauna, which are absent of very scarce in the Em- 

 barras system about Charleston. These are : the spotted 

 sucker, silvery minnow, river chub, tadpole cat, pirate perch 

 and orange-spotted sunfish. These favmal differences are not 

 remarkable when we consider that the two streams are in 

 very different drainage basins, the Mississippi and the Wa- 

 bash ; but they signify a marked distinctness of the two sys- 

 tems geographically in the Charleston region.
