that this identification is correct, but as yet I have not found a genuine photogenis in 
Atlantic waters. 
11. Notropis procne (Cope). S. 
Eather common in the river. These specimens agree very well with Professor 
Cope’s description of Hybopsis longiceps, except in the form of the preorbital bone, which 
is but little longer than deep. Compared with N. microstoftms (Rafinesque) = (A. delicio- 
sus stramineus) from White Eiver, Indiana, N. longiceps difi'ers chiefly in the higher fins, 
more elevated back, slenderer tail, and more rapidly ascending profile. The scales 
area little larger in A. longiceps (lat. 1. 34), and the dark punctulations along side and 
at base of caudal are more conspicuous. There is a striking difference in the height of 
the dorsal fin, its longest ray being about as long as head in W. longiceps adult, and about 
three fourths head in N. microstomus of the same size. The lateral line is also less 
decurved in N. longiceps than in the other. 
I have no specimens of Notropis procne for comparison. My specimens agree with 
Cope’s description of the latter and with my own notes on it. I therefore regard 
longiceps as a synonym of procne. 
I may here note that Hemitremia vittata Cope, from the Holston, seems to be the 
same as Phoxinus flammeus Jordan and Gilbert. The teeth are described by Cope as 
4-5 instead of 2, 4r-5, 2, but in other respects Coj)e’s description agrees with our speci- 
mens. The species may stand as Phoxinus vittatus, 
12. Phoxinus margaritus (Cope). S. 
A single specimen. Head, 4 in length ; depth, 4|; A. I 9 (not I 8) ; dorsal low; 
scales, 58; lateral line incomplete, tlie pores mostly ceasing not far behind middle of 
body ; body dusted with black specks ; a narrow lateral streak of plumbeous on cau- 
dal peduncles. 
13. Hybopsis kentuckiensis (Rafinesque). S. 
Common in the river. 
14 Semotilus bullaris (Rafinesque). S. 
One small specimen. 
15. Semotilus atromaculatus (Mitchill). H., W. 
Scarce. Lat. 1. 53 to 60. 
16. Rhinichthys atronasus (Mitchill). S.,H.,W. 
Very common in brooks and springs, scarce in the river. Lat. 1. 63. A black lat- 
eral band, with yellow or orange below it. Scales of back more or less mottled. 
17. Rhinichthys cataractae (Cuv. Val.). S.,H., W. 
Very common. Lat. 1. 62; snout much projecting; insertion of dorsal midway 
between anterior nostril and base of caudal. 
18. Exoglossum maxillingua (Le Sueur). “Nigger-Dick.” S.,H.,W. 
Very common in the river. Lat. 1. 52. 
19. Fundulus diaphanus (Le Sueur). S. 
Two large specimens from the river. Lat. 1. 44. Body in one specimen with 
about 15 silvery cross-bands, most of them narrower than the dark interspaces; back 
and fins unspotted. The second specimen has about 11 very narrow dark cross-bars.
