ON A COLLECTION OF FISHES FROM EAST TENNESSEE. 



By Dr. James A. Henshall. 



(Read June 4, 1889.) 



Mr. Charles Dury, recently, while collecting insects in East Ten- 

 nessee, collected a small lot of fishes, consisting of five species, two 

 of which seem to be new to science. 



The specimens were procured at Whiteside, Tennessee, a station on 

 the Memphis and Charleston Railroad, from a small tributary of the 

 Tennessee River, and are now in the museum of the Society. The 

 fishes were in their spring, or breeding dresses, which were unusually 

 and remarkably brilliant, due no doubt to the clear and pure water of 

 the mountain stream in which they were taken. Following is a list of 

 the collection : 



Campostoma anomalum (Rafinesque). One example 2^ inches 

 in length. The specimen differs from the usual form of this widely- 

 distributed species, in its more slender body, long caudal peduncle and 

 deeply forked caudal fin. 



The coloration differs also, in being silvery instead of brassy, with 

 the usual black or dark mottling. Throat and belly rosy. No oper- 

 cular spot ; dorsal and anal fins plain, the usual dusky bar being 

 absent. 



Head 4% ; depth 5. Teeth 4-4. Scales 6-51-5. D. 8. A. 7. 



Chrosomus erythrogaster (Rafinesque). Three examples 2^ 

 inches in length. Body fusiform, tapering regularly, little compressed. 

 Mouth small, oblique, terminal. Lateral line extends from opercle to 

 ventral fin. 



Coloration : Brownish on top of head and back, shading into a 

 black border extending from head to caudal fin. Mouth, lips and 

 throat jet black. A broad, jet black band passing from mouth, 

 through the eye and extending to caudal ; under the dorsal fin it gives 

 off a branch leading toward the anal fin. The space between the 

 black bands, the entire belly, and the suborbital space are intense 

 scarlet; fins more or less scarlet; opercle, silvery. 



Head in length, 4^ ; depth, 4^. Teeth, 4-5. 90 scales along the 

 lateral line. D. 7. A. 8.
