47. Etheostoma rupestre Gilbert & Swain. 
North Eiver near Tuscaloosa. 
48. Etheostoma (Nothonotus) jordani, sp. nov. (Plate xliii, flg. 2.) 
Closely related to E. rufolineatwn, from which it differs conspicuously in form 
and coloration. 
Body rather deep, compressed, the caudal peduncle slenderer than in related 
forms, the anterior profile much more convexly decurved, the snout blunter. 
Mouth terminal, oblique, rather small, the maxillary scarcely reaching vertical 
from front of pupil, 3f in head. Premaxillaries on level of lower margin of orbit, the 
jaws about equal. Eye equaling snout, 4^- to 4^- in head, twice interorbital width. 
Breopercle entire. Gill membranes not united. 
Spinous dorsal high, the spines strong, the membrane from last spine not join- 
ing base of soft dorsal; highest dorsal spine slightly more than half length of head. 
Base of soft dorsal IJ in base of spinous dorsal. Anal shorter than soft dorsal, and 
inserted more anteriorly, the first spine longer and stronger than the second, two- 
thirds the height of longest anal ray, and one-third length of head. Caudal fan- 
shaped when widely spread. Pectorals reaching beyond tips of ventrals, in head ; 
ventrals extending half way to base of second anal siiine. 
Scales large, strongly ctenoid, present on nape, the breast naked; opercles scaly, 
head otherwise naked. No enlarged black humeral scale. Lateral line complete, or 
wanting on occasional scales in its course, straight. 
Head to 3^ in length ; depth 4| to 4. D. x or xi-10 to 12 ; A. I. 7 or 8 ; Lat. 
1. 43 to 55 (averaging 48). 
Colors probably brilliant in life. In spirits, the males are olivaceous, darker 
above, the sides, with faint, narrow longitudinal dark lines running between the rows 
of scales. Back with 8 black cross-bars wider than the interspaces; the first on nape, 
the second under and in advance of origin of spinous dorsal, the fifth under first rays 
of soft dorsal. The first bar is continued downwards into axil of pectorals, the others 
usually not reaching lateral line. Middle of sides with irregular bars usually formed 
of disconnected blotches, and 9 or 10 in number. A pair of black blotches at base of 
median caudal rays, and sometimes a pair at base of outer rays. Pin rays all black- 
ish, the membranes lighter. Basal half of anterior portion of spinous dorsal black, 
its margin narrowly white, a narrow submarginal dark line below it. Soft dorsal and 
caudal with a wide white (probably orange in life) submarginal band, the tips nar- 
rowly black. Anal and ventrals similar, but without black margin. Pectorals uuir 
form dusky, with light membranes. Snout and top of head blackish ; a small black 
spot behind eye. Fins iirobably blue and orange in life. Females mottled, with fins 
barred. Abundant in Choccolo Creek, Oxford, and Chestnut Creek, Verbena. 
49. Etheostoma squamiceps Jordan. {=Etheo8toma jyarvipinnia Gilbert & Swain. ) 
This widely distributed species varies extremely in appearance, in number of fiu- 
rays, and in squamation. Specimens from the Alabama basin {parvipinnis) are usually 
smaller, with less elevated fins and fewer fin-rays, but seem to vary iierfectly into the 
typical form. 
From Calera, 
50. Etheostoma whipplei alabamae Gilbert & Swain. 
Abundant in tributaries of the Black Warrior River. Also taken in the Big 
Cahawba, at Helena.
