EXPLOKATIONS OF THE ALLEGHANY REGION AND WESTERN INDIANA. 165 
instead of one ; lateral shades broader. Gill-membranes considerably united ; pre- 
opercle serrulate, at least in young specimens. 
75. Etheostoma evides (Jordau & Copeland). W., V. 
Common in the river. Scales 61. 
76. Etheostoma cceruleum Storer. V. 
Less common than farther north. Scales 46. 
77. Etheostoma Jessie (Jordan & Brayton). V., W., C. 
This si>ecies seems here to approach very closely to E. coeruleum, there being very 
little difference in the specimens from Vincennes except that cceruleum has naked 
cheeks while in jessice the cheeks are scaly. Scales 50, 54, 55, 55 in four specimens. 
The species or group of species called E. jessiw {E. asprigene, E. swaini) is much in 
need of farther study. 
E. iowce Jordan & Meek has a form more like that of E. eos {fusiforme var.), and 
color markings similar to those of the latter, including three spots at base of caudal; 
its lateral line is, however, nearly straight, as in E. jessice. 
78. Etheostoma squamiceps Jordan. G., B. 
In shallow, sandy streams. This species is allied rather to E. whipplei than to E. 
Jiahellare. Scales 55 to 60 ; opercles scaly ; cheeks scaly or naked ; three dark spots 
across base of caudal ; no bright red or blue markings ; body covered with dark 
specks. 
79. Etheostoma fusiforme (Girard). W., C. 
Rather scarce. These specimens represent the form or variety called palustre. 
80. Aplodinotus grunniens (Rafinesque). P., W.. M. 
Common. 
R.— LOWER OHIO RIVER. 
Collections were made in two streams tributary to the Ohio in southwestern 
Indiana. 
1. Big Pigeon Creek, at Evansville, Ind. September 10. This is a sluggish, muddy 
stream, usually with muddy bottom. Collections were, however, made at a point 
where the bottom is of sandstone and shingle. The rocks are smooth and bare, there 
being no algae or other vegetation in the stream. The following is the list : 
1 . Noturus nocturnus Jordau & Gilbert. 
Head much less broad than in N. gyrinus and less blunt; no black streak along side 
of body; pectoral spine in head, its inner edge entire. In the latter respect these 
two specimens differ from the Arkansas types of N. noeturnus. 
2. Laptops olivaris (Rafinesque). 
3. Ictalurus punctatus (Rafinesque). 
4. Ictiobus bubalus (Rafinesque). 
5. Ictiobus difformis (Cope). 
6. Moxostoma duquesnei (Le Sueur). 
7. Hybognathus uuchalis (Agassiz). 
8. Notropis megalops (Rafinesque). 
9. Notropis whipplei (Girard).
