Head, 3f in length ; depth, of to 6. D. XI or XII, 13 or 14 ; A. II 

 11 or 12. Lat. 1. 74|^ L. 3^ in. ' 



Color : Olivaceous, the back with 8 to 10 dusky cross-bars wider than 

 the interspaces; these dorsal bars usually continuous with an equal 

 number on middle of sides, the latter terminating below lateral line in 

 V-shaped prolongations, much like those in Efheostoma hlennioides. lu 

 one specimen (an adult S ) the first two bars are partially confluent on 

 sides, the anterior one including the axil and ending in a black spot 

 below pectorals, the second encircling body behind ventral fins ; bars 

 behind front of anal in this specimen also completely encircling body. 

 Back and sides marked with many small bright carmine-red spots, ir- 

 regularly disposed in the light interspaces; in the male specimen they 

 are much more numerous, those on hinder part of body confluent, form- 

 ing narrow bars, one down the middle of each light space. A dark 

 streak forward and one backward from eye, none downward ; opercle 

 and top of head dusky. 



Spinous dorsal dusky, the base marked with fine red spots, the fin 

 broadly margined with a bright carmine band. Soft dorsal barred with 

 alternating series of dark and of reddish spots. Caudal with wide bars of 

 dark and red. A pair of small jet-black spots on caudal peduncle at 

 base of median caudal rays. Anal dusky at base. Pectorals and ven- 

 trals light orange, indistinctly barred with dusky. 



Two specimens, each 3f inches long, were taken by the writer, in 

 company with Mr. Seth E. Meek, in the headwaters of the Niangua 

 Eiver, near Marshfield, Mo. One of these is deposited in the U. S. iSla- 

 tioual Museum, the other in the museum of the University of Cincin- 

 nati. 



7. Etheostoma niangua spilotum Gilbert, subsp. nov. 38319. 



Diflering from the above in squamatiou only, the scales being much 

 larger, and the lateral line incomplete in all specimens examined. The 

 scales along anterior portion of base of spinous dorsal have like those 

 on nape lost their ctenoid chara^jteristics, but are not reduced in size, 

 and are still regularly disposed in series continuous with those of sides. 

 In typical nianguce they are much reduced, and not in definite series. 



Head, 3i to 3f ; depth, 5^ to 6^. Eye 5 in head, in specimens 2 to 3 

 inches long. D. X or XI-12 or 13 ; A. II, 10 or 11. Lat. 1. 58 to 60, 

 the pores absent on the posterior 5 to 13 scales, and occasionally on 

 single scales more anteriorly. Eight series of scales between lateral 

 line and base of spinous dorsal. 



Color in life: Olive green above, light below; back with S dark cross- 

 bars formed of dusky mottliugs ; continuous with these, or in other 

 ca^es alternating with them, are 8 V-shaped markings on middle of 

 sides; sides and above spotted with reddish orange occupying the 

 light interspaces. A narrow black bar from upper opercular angle 

 through eye encircling the snout. Pectorals and ventrals translucent,
