FISHES OF THE MISSOURI RIVER BASIN. 423 



The formula for tho dorsal fins was found to bo vm-9 in 5; vm-10 in 1, 

 ix-9 in 1, ix-10 in 3, ix-11 in 2, ix-12 in 1, x-10 in 4, x-11 in 2, and xi-11 in 



I. In 25 specimens which we collected at South Bend and which wo examined 

 for Professor Meek, the formula was ix-10 in 9, x-11 in 5, x-10 in 4, ix-11 in 

 4, ix-9 in 2, and xi-10 in 1. In the single specimen upon which E. quappelle 

 was based it is ix-9. The anal fin is usually n, 7, though occasionally it is 



II, 6, or ii, 8. The specimens from Crow Creek near Chamberlain, 39 in num- 

 ber, differ somewhat from Creighton specimens in having the scales smaller, 

 usually 55 to 58 in lateral line, fewer pores developed, and tho cheeks and 

 opercles more nearly naked. Tho largest specimens in our collections are 

 from Creighton, Mitchell, and Niobrara and are 2| inches long. 



131. Etheostoma cceruleum spectabile (Agassiz). Ellis, Ellis County, Kans. (as 



P(ceilichthys cceruleus, Gilbert, 1884); Kansas River (as E. variation, Graham, 

 1885); Ellis, Kans. (as E. variatum, Gilbert, 1885 and Cragin, 1885a) J Black- 

 water Creek, Brownsville, Saline County, Mo. ; Flat Creek, Sedalia, Mo. ; 

 Grand River, Clinton, Mo. ; Tabo Creek, Calhoun, Mo. (as Etheostoma variatum 

 spectabile, Jordan & Meek, 1885) ; Bigler, Texas County, Mo. (Call, 1887) ; 

 Little Piney River at Newburg and Arlington, Mo. ; Big Piney River, Cabool, 

 Mo. ; Gasconade River, Arlington, Mo. ; Lock Fork, Mansfield, Mo. ; Osage 

 Fork, Marshiield, Mo. ; Jones Creek and Marais River, Dixon, Mo. ; Niangua 

 River, Marshfield, Mo.; Sac River, Springfield, Mo. (Meek, 1891). Whether 

 all these references belong properly to the variety spectabile is doubtful; 

 some of them may have been based upon typical cceruleum specimens. In the 

 Ozark region of Missouri it is probable that only spectabile occurs. 



132. Etheostoma lepidurn (Baird & Girard). Shunganunga Creek, Topeka; spring 



near Maple Hill, Wabaunsee County, Kans.; Ellis, Kans. (Gilbert, 1886); 

 north fork of Solomon River, Lenora, Kans. ; Saline River, Wakeeney, Kans. ; 

 Smoky Hill River, Wallace, Kans. (Hay, 1887). 



133. Etheostoma punctulatum (Agassiz). Jones Creek, Dixon, Mo.; Big Piney 



River, Cabool, Mo. ; Osage Fork, Marshfield, Mo. ; Lock Fork and Niangua 

 River, Mansfield, Mo. (Meek, 1891). 



134. Etheostoma flabellare Rafinesque. Fan-tailed Darter. Jones Creek and Marais 



River, Dixon, Mo.; Little Piney River, Mo.; Osage Fork, Marshfield, Mo.; 

 Niangua River, Marshfield, Mo. (Meek, 1891). 



135. Boleichthys fusiforniis (Girard). Maraia des Cygnes (as Etheostoma fusiforme, 



Graham, 1885). 



136. Boleichthys exilis Girard. Little Muddy River (as Boleichthys exilis type, 



Girard, 1859); Cannon Ball River (as B. warreni type, Girard, 1859). 



137. Microperca punctulata Putnam. Jones Creek, Dixon, Mo. (Meek, 1891). 



138. Roccus chrysops (Rafinesque). White Perch. Kansas River and Mill Creek, 



Kans. (Graham, 1885) ; Big Sioux River and Silver Lake, Iowa (Meek, 1892). 



139. Morone interrupta Gill. Yellow Bass. Tho ouly record of the occurrence of 



this fish in the Missouri Basin is that given by Cragin (1885 a), who reports 

 it from the Kansas River (presumably at Lawrence) on the authority of 

 Prof. Frank H. Snow, of the Kansas State University. 



140. Aplodinotus grunniens Rafinesque. Fresh-wafer Drum. Milk River (as Am- 



blodon grunniens, Suekley, 1860) ; Missouri River, St. Joseph, Mo.; Grand

 Kansas River (Graham, 1885, and Cragin, 1885 a); Big Sioux River at Sioux 

 City (Meek, 1892) ; Elkhorn River at Fremont (Meek, 1894).
