may be compared with the other known species, Xenisma 

 catenata,* as follows : — 



Common characters. Dorsal and anal long, similar, and placed directly- 

 opposite each other. Branchiostegals 4. Ventrals with 6 rays ; intestinal 

 canal short; teeth pointed, in bands. Males with orange spots, females 

 marked with short olive- brown lines. 

 a. D. 13; A. 13; lat. 1. 53; dorsal and anal greatly elevated 

 in $ , the longest ray of the dorsal reaching caudal when 

 laid back, its height equal to the depth of the body ; 

 orange spots irregularly placed, never forming continu- 

 ous rows. Length 3 to 4 inches. Habitat. Head waters 



of the Alabama River. stellifera. 



era. D. 13 or 14; A. 15; lat. 1. 47; dorsal and anal much less 

 elevated even in $ , falling far short of caudal when laid 

 back; the orange (or brown) spots, one on each scale, 

 forming regular lines along the sides. Length, 4 to 6 

 inches. Habitat. Head waters of Tennessee River, catenata. 



My specimens of X. stellifera show the following charac- 

 ters : — 



Head 3| to 4 in length, flattened and broadened above in the usual 

 Fundulus fashion : eye large, about 4 in head. Body rather long; depth 

 about 5 in length; scales closely imbricated, much deeper than long, as 

 in Luxilus, their edges punctate with black, 52 or 53 transverse rows of 

 scales. 



Dorsal beginning directly over anal, its last rays in males highly ele- 

 vated, reaching base of caudal, their height equal to depth of body; anal 

 similar, more elevated in front, and less so behind, the last rays falling 

 just short of caudal. In female specimens, these fins are less elevated, 

 but still very high. Pectorals reaching beyond base of ventrals, the lat- 

 ter reaching anal in £ , but falling just short in £. 



D. 13 (rarely 12) ; A. 13, rarely 12; V. 6; B. 4. 



Colors brilliant; general color a bright pale greenish or livid blue, 

 bluish silvery below with a golden lustre forwards. Body, cheeks, etc., 

 in $ with large, bright, dark orange spot*, irregularly placed, not follow- 

 ing the rows of scales, and not always on the middle of the scales. These
