FISHES OF THE TENNESSEE BASIN. 57 



Gila estor. 

 Qaassilabia lacera. 

 Carpiodes bisou. 



Bubalicbthys urus. 

 Am ill calva. 

 Acipenser maculosus. 



Ill all, twenty species. 



Increased knowledge will considerably modify these lists. It is 

 probable that the sixteen species in the first list, with the probable 

 exceptions of Noturus eleutherus and SalveUnus fontinalis, will be found 

 to inhabit the lower part of the river basin, if sought for in suitable 

 localities. It is likely that the tributaries of the Tennessee having their 

 source in the Cumberland Mountains in Alabama have the same fish- 

 fauna as similar streams rising in the Cumberland Mountains in Virginia. 



About twelve species are at present known only from the Tennessee 

 Kiver and its tributaries. These are : — 



Hadropterus aurantiacus. 

 (Etheostoma) cinerea. 

 (Etheostoma) tessellata. 

 Xothonotus vulneratus. 

 Nothonotus rufllineatus. 



(Lepiopomus) bombifrous. 

 Alburnops spectrunculus. 

 Hydrophlox lacertosus. 

 Phoxinus flammeus, 

 Episema leucioda. 



Poecilichthys jessioe. Ceratichthys monachus. 



As we go from the Alabama to the Tennessee, we note an increased 

 resemblance in the fish-fauna to that of the Ohio arid Upper Mississippi 

 region. The following are some of the Northern or Western types 

 added : — 



Diplesium, Etheostoma, Poecilichthys, Lahidesthes, Zygonectes (proper), 

 Episema, Hemitremia, Chrosomus, Phoxinus, Placopharynx, Quassilabia.

 Spring at Cumberland Gap. Abundant in the French Broad Eiver 

 (Cope) and in the Ilolston.
