491. NOTROPIS AMCENUS (Abbott). 



Head 4 ; depth 5fr, (4f to 5i) ; eye 31. D. 8 ; A. 10 ; scales 6-39-3. Close 

 to Notropis rubrifrons, but the scales before dorsal smaller, as in N. photo- 

 genis. Body elongate, compressed ; eye large, longer than snout. Mouth 

 large, oblique, the jaws subequal, the maxillary to front of eye ; 22 to 25, 

 (rarely 18 to 20) scales before dorsal; lateral line much decurved. Dorsal 

 high, behind ventrals; pectorals moderate. Translucent green, sides 

 silvery, with sometimes a faint plumbeous band ending in an obscure 

 plumbeous spot. Length 3f inches. Clear streams east of the Alleghanies 

 from the Raritan to the Neuse ; abundant ; formerly confounded with 

 N. photogenis, of which it may be a variety, (amosnus, attractive.)

Head 3f ; depth 4|; eye 3. D. 8; A. 10; scales 6-38-3; teeth 2, 4-4, 1. Body 

 short and deep, compressed and somewhat elevated. Head rather large, 

 deep, bluntish. Mouth moderate, termiual, oblique, lower jaw slightly 

 included ; upper lip opposite middle of eye ; maxillary extending to front 

 of orbit. Eye very large, longer than snout; interorbital space broad, 

 flattish. Lateral line much decurved. Scales before dorsal large, in 13 to 

 15 rows. Fins moderate ; dorsal well behind ventrals ; tips of ventrals 

 extending to last dorsal ray ; caudal peduncle moderate. Coloration very 

 pale green ; sides with a bright silvery band ; scales with very little dark 

 edging ; a dark line at base of dorsal ; males in spring with the snout pro- 

 fusely tuberculate. Length 3 inches. Rivers of Carolina from the Cape 

 Fear to the Santee ; abundant, replacing the allied amcenus, from which it 

 differs in the deeper body and larger nuchal scales. (CKE TTTIKOS , observant, 

 from the large eye.)
