497. NOTROPIS ROSEIPINNIS, Hay. 



Head 4i; depth 4 ; eye 3|. D. 8 ; A. 11 ; scales 8-45-3. Body long and 

 slender, much compressed. Mouth large, oblique, the lower jaw some- 

 what projecting, the maxillary reaching vertical from front of ey. Eye 

 large, slightly longer than snout. Scales small, especially along the back, 

 somewhat higher than long, but not so closely imbricated as in N. bellus. 

 Lateral line much decurved. Dorsal far back, midway between pupil 

 and base of caudal, considerably posterior to ventrals ; pectorals not 

 reaching ventrals, the latter to vent. Dark ; scales above all with black 

 points; a plumbeous lateral band, ending in a vague caudal spot; a nar- 

 row dorsal band ; a black spot on the upper anterior portion of dorsal 

 and also on anal, each surrounded by a diffuse blotch ; tip of ventrals 

 and edge of pectorals dark ; vertical fins red. Length 2 inches. Sandy 

 streams of the Gulf States, from the Escambia to the Chickasawha.

* "A comparison of these specimens from the Tennessee River with others from the Roanoke 

 River (ardens), the Pamlico and Neuse (matutinus), the Wabash in Indiana, (cyanocephalus) [rather 

 lythrurus ; cyanocephalus came from Racine, Wisconsin], various streams in Illinois (atripes), and- 

 the Arkansas River (umbratilis) [ nigripinnis], has shown the impossibility of recognizing any of 

 these forms as distinct species. Matutinus is smaller and paler than ardens andshows less brilliant 

 coloration, these differences being apparently dependent on the sluggish character of the streams 

 it frequents, with their frequent sandy stretches. The resemblance between specimens from the 

 Roanoke and the Tennessee is very close. Both have larger mouth and eye, more brilliant color- 

 ation, and more elongate form than in specimens from the north and west. Our specimens 

 from the Tennessee, however, average distinctly deeper than typical ardens, and are further 

 characterized by the presence, in males, of several (5 to 8) dark steel blue, vertical bars, irregular 

 in position and shape. This form I here distinguish provisionally as subspecies fasciolaris. In 

 Tennessee and Kentucky it undoubtedly passes insensibly into the form common in tributaries 

 of the Ohio and Mississippi (cyanocephalus, atripes), which shows usually an evidently deeper body, 

 a smaller eye, and a tendency to the accumulation of black pigment in the tips of the ventrals 

 and the anterior rays of the dorsal and anal. Typical umbratilis from Kansas and Arkansas 

 appears very distinct from the more easterly form. It has the larger eye of fasciolaris, a very 

 deep body, and adult males have all the fins largely black and the sides uniform dusky. Further- 

 more, the black spot at the base of the anterior dorsal rays, so characteristic of related forms, is 

 here indistinct or wanting. In Iowa and Missouri, however, umbratilis appears to pass imper- 

 ceptibly into cyanocephalus, some specimens lacking the dorsal spot, while others from the same 

 locality, and not otherwise differing, have it well developed. 



"I have thought it best, therefore, to consider all these forms as poorly defined varieties of a 

 single widespread species, which may stand provisionally as N. umbratilis umbratilis, N. umbratilis 

 cyanocephalus, N. umbratilis fasciolaris, N. umbratilis ardens, and N. umbralilis matutinus. East of the 

 Alleghanies the species has not been recorded north of the Roanoke nor south of the Neuse, and 

 is not known from the Gulf States south of the Tennessee and Arkansas Basins. Rafinesque's 

 BemotHua diplsemius, so long identified with this species, is evidently Semotilus atromaculatus, as a 

 synonym of which it must appear." (Gilbert, Bull. U. S. Fish Comm., ix, 1889, 148.)
