moderately compressed, the back somewhat elevated anteriorly in old 

 examples. Head conical, rounded above ; eye moderate, 1| in snout (6 inches 

 long), 5 in head ; about as long as maxillary. Mouth terminal, very 

 oblique, the lower jaw included; the snout not prominent; the short 

 maxillary not reaching eye. Dorsal high and pointed; anal short, rather 

 high; pectoral long, reaching distance to ventrals, which reach vent; 

 ventrals below front of dorsal, which is behind middle of body. Scales 

 with edges largely exposed; lateral line running low, complete. Dusky 

 olive above and on sides to level of ventrals, with brassy luster 

 everywhere: middle of belly only white, a pale yellowish area between 

 pectorals and ventrals; head brassy, dusky above, closely dotted above 

 and on sides ; body everywhere closely dotted with black, except on mid- 

 dle line below; fins all dusky, with dark points. This species is well sep- 

 arated from all the R. symmetricus tribe. 



Page 247. Luxilinus occidentalis is the young ofLavinia exilicanda, Baird 

 & Girard (p 209), and must be placed in the synonymy of that species. 

 Luxilinus is a pure synonym of Lavinia.

Page 254. For Azteca, line 22, substitute Aztecula, Jordan & Evermanu, 

 new subgenus. The former name is preoccupied by Azteca, Forel, 1878, a 

 genus of ants. The same substitution to be made in the key on page 255 

 and on page 258.

Head 4i; depth 5; eye 3 in head; snout 3. D. 8; A. 8 or 9; scales 

 6-35-3; teeth 4-4. hooked. Body rather slender, moderately compressed; 

 head short, snout bluntly pointed ; mouth moderate, somewhat oblique, 

 lower jaw slightly included, maxillary scarcely reaching front of eye; 

 premaxillaries protractile. Eye large; posterior edge of pupil at middle 

 of longitudinal length of head; iuterorbital width greater than eye; 

 caudal peduncle long and slender. Dorsal fin inserted well behind base 

 of ventrals, a little nearer base of caudal than tip of snout, its longest 

 rays shorter than head, but slightly longer than longest anal rays ; ante- 

 rior dorsal and anal rays longest; pectoral li in head; ventrals reaching 

 origin of anal; caudal deeply notched, the lobes long and pointed. 

 Scales large, lateral line incomplete, developed only on 6 to 10 scales. 

 Back olivaceous; side with a broad black band extending from snout 

 through eye, and ending in a rather distinct black spot on base of caudal, 

 the black spot in some specimens (probably mature males) surrounded by 

 orange; the black line bordered above by a narrow orange or reddish 

 line, less distinct, or even whitish, in females and immature individuals; 

 under parts plain; fins all plain; dorsal and caudal somewhat dusky; 

 dusky specks on body along base of anal and under side of caudal pedun-
