FISHES FROM ARKANSAS AND INDIAN TERRITORY. 
349 
No fewer than 25 of the 61 species found in the St. Francis were not found in 
western Arkansas and eastern Indian Territory. They are the following: 
1. Lepisosteus platystomus. 
2. Amia calva. 
3. Noturus gyrinus. 
4. Catostomus nigricans. 
5. Notropis cayuga. 
6. Notropis xrenoceplialus. 
7. Notropis megalops. 
8. Funclulus scartes. 
9. Zygonectes guttatus. 
10. Umbra limi. 
11. Apliredoderus sayanus. 
12. Elassoma zona turn. 
13. Centrarclius macropterus. 
14. Pomoxis sparoides. 
15. Ambloplites rupestris. 
16. Lepomi8 garmani. 
17. Etbeostoma pellucidum. 
18. Etbeostoma shumardi. 
19. Etbeostoma aspro. 
20. Etbeostoma scierum. 
21. Etbeostoma bistrio. 
22. Etbeostoma jessise. 
23. Etbeostoma saxatile. 
24. Etbeostoma copelandi. 
25. Morone interrupta. 
Adding these 25 species to the 58 found in western Arkansas and eastern Indian 
Territory gives a total of 83 species of fishes as the result of less than three weeks’ 
collecting in these waters. There are but few regions in the United States that will 
yield so many species of fresh-water fishes. 
MOLLUSKS COLLECTED IN OLD RIVER, NEAR GREENWAY, ARKANSAS. 
No special effort was made to collect the mollusks occurring in the water examined. 
Some little time was given to collecting the different species in Old River, the names 
of which are given in the following list. I am indebted to Mr. Charles T. Simpson, of 
the National Museum, for the specific determinations and for the technical notes on 
each. 
Unio pyramidatus Lea. Scarce. 
Unio gibbosus Barues. A tbin, compressed, elon- 
gated variety, found rarely throughout the 
range of the species. Quite common. 
Unio parvus Barnes. Scarce. 
Unio texasensis Lea. Scarce. 
Unio tuberculatus Barnes. Scarce. 
Unio turgidus Lea. So far as I know this species 
has not hitherto been reported north of 
southern Louisiana. 
Unio anodontoides Lea. A pale, rather delicate 
variety, found iu the Gulf States; abundant. 
Unio lienosus Conrad. The peculiar variety of this 
species found here has not been reported 
hitherto north of Columbus, Mississippi; not 
common. 
Unio castaneus Lea. A common southern species 
found as far north as Clinton, on the Little 
Red River, Arkansas, 125 miles southwest of 
Greenway ; common. 
Unio hydianus Lea. Very abundant. The most 
northern limit heretofore known was Little 
Rock and Wittsburg, Arkansas. 
Unio cerinus Conrad. A species of southern 
Louisiana and Mississippi, and not pre- 
viously known north of Little Red River. 
There can be no doubt that these shells are 
genuine cerinus. Abundant. 
Unio undulatus Barnes. Scarce. 
Anodonta imbecillis Say. Scarce. 
Anodonta edentula Say. Not common. 
Anodonta opaca Lea. A form not known hitherto 
north of Little Rock, Arkansas. Scarce. 
Sphcerium solidulum Prime. 
Pleurocera elevata Say. 
Campeloma coarctata Lea. A southern species. 
Planorbis trivolvis Say. 
Vivipara subpurpurea Say. Banded. 
This collectiou is remarkable from the fact that it contains no less than six species 
of Unionidm found at a locality farther north than they have ever been reported from 
before. In fact the species of general distribution throughout the Mississippi Valley 
that were taken at this locality have a most decidedly southern aspect, and the entire 
collection is such as one would expect to find among the streams near the shores of 
the Gulf of Mexico.
