Southward it gives place to 



428b. NOTROPIS HUDSOXH'S AMARUS (Girard). 



Very close to var. hudsoniits, characterized by the longer and less obtuse 

 head, 4* to 4? in length, the eye 3* in head, longer than snout; the cau- 

 dal spot faint or wanting, and the teeth 1, 4-4,0. Dela\Yare and Potomac 

 rivers. This is not unlikely a distinct species, as Abbott has contended, but 

 there is some evidence of its intergradation with hudsonius. (ama7-us, 

 bitter, the type from brackish water.)

This form gives place still further southward to 



4'>8c. NOTROPIS HUDSONIUS SALUDAXUS (Jordan & Braytou). 



Head 4i ; depth 4^ ; eye large. Si, (3 to 4). D. 8; A. 8; scales 5-39-3; 

 teeth 1, 4-4, 0, two or three of the teeth obtuse, not hooked, only one or 

 two of them showing a grinding surface. Body elongate, but less so than 

 in var. hndnomus ; moderately compressed. Caudal peduncle long. Head 

 large, rather heavy and gibbous forward, the muzzle rounded in profile. 

 Mouth moderate, subinferior, the maxillary not reaching eye. Scales large, 

 thin and loose, about 12 in front of dorsal. Lateral line somewhat 

 decurved in front. Fins rather small ; pectorals not reaching ventrals, 

 the latter not to vent. Coloration pale olivaceous, nearly white, with 

 traces of a plumbeous lateral streak, this sometimes appearing as a black 

 lateral band, (var. euryopa), and sometimes leading to a black caudal spot 

 as in hudmnius. Length 4 inches. Coastwise streams from the James to 

 the Ocmulgee. Close to subspecies «ma?-HS with which it may intergrade. 

 Head notably longer, 4^ to 4^, the snout especially longer, as long as eye, 

 projecting beyond the inferior mouth.

 429. NOTROPIS ORNATUS (Girard). 



Head 3f to 4; depth 3; eye 3f to 4. D. 8; A. 7; scales 7-40-4, those 

 before dorsal large, 17 ; teeth 4-4. Body stout and compressed, the back 

 arched, the head very blunt, thick and rounded, almost spherical in the 

 male. Mouth small, somewhat oblique, the cleft mostly anterior; the 

 jaws equal. Eye smallish. Scales deep, very closely imbricated, those on 

 sides much higher thau long ; lateral line decurved. Dorsal a little behind
