SALEMA (Spanish name) : 



a. Occipital crest rather thin, its honeycomb structure not exposed. Species with 

 streaks of steel-blue and golden, the dark cross bands narrow, disappearing with 

 age, about one- third the interspaces ; a black humeral spot. 

 b. Dorsal spines 13 ; incisors f on each side ; side of back with 8 or 9 golden streaks, 



which are narrower than the metallic-blue interspaces. 



c. Scales 9-48-15 ; pectoral fin not quite reaching second anal spine; body rather 



deep and compressed. Incisors | on each side, entire, or with a shallow 



notch. Fifth dorsal spine highest, 2 to 2 in head; second anal spine 



strong, recurved, 2 in head. Olivaceous, silvery below, the upper parts 



with golden longitudinal stripes alternating with bluish interspaces; 



humeral spot larger than eye. UNIMACULATUS, 1733. 



cc. Scales 7 or 8-48-15 ; pectoral tin reaching second anal spine ; body rather 



less deep, the snout a little longer; ventrals shorter, 5 to 5|- in head; 



otherwise essentially as in the preceding, of which it is the Pacific 



coast representative. POURTALESII, 1734. 



bb. Dorsal spines 12; incisors % on each side. Profile with a slight depression above 



the eye ; second anal .spine much longer than the third. Color grayish, belly 



white; 8 golden longitudinal bauds; a black shoulder spot. TRIDENS, 1735. 



AROHOSARGUS : 



aa. Occipital crest broad, its honeycomb structure plainly exposed at its upper margin; 

 dorsal spines 12 ; species \vit hout blue or golden markings, buT with about seven 

 broad black cross hands crossing the body; no distinct shoulder spot. Body 

 much compressed; dorsal outline strongly arched; ventral outline almost 

 straight. Profile straight and steep anteriorly. Incisors f, entire or slightly 

 emarginate, serrate in the young; molars in 3 series above, in 2 below, those 

 of the inner series larger, those behind the incisors very small. Highest dorsal 

 spine I 1 , in head; second anal spine about twice in head, much longer than 

 third. 

 d. Incisors broad, their breadth about half their length. Scales 8-48-15. 



PROBATOCEPHALUS, 1736. 

 dd. Incisors narrower, their breadth 2% in their length. Scales 7-44-14. 



ARIES, 1737. 



Subgenus SALEMA, Jordan & Evermann. 

 1733. ARCHOSARGUS UNIMACULATUS (Bloch). 



(SALEMA.) 



Head 3; depth 2 to 2; eye large, 3| to 4 preorbital, or 1 to 1 in 

 interorbital width. D. XIII, 10; A. Ill, 10 or 11; scales 8 or 9-45 to 50-14 

 to 16. Body rather deep and compressed, profile rounded, steep; mouth 

 moderate, maxillary not reaching front of orbit, 3 to 3 in head ; occipital 

 crest rather thin, its honeycomb structure not exposed. Incisors f on 

 each side, entire, or with a shallow, notch ; molars 3-rowed above, 2-rowed 

 below; gill rakers small, about 6-f-8; cheeks with 5 rows of scales. Fifth 

 dorsal spine highest, 2 to 24- in head; second anal spine strong, recurved, 

 2 to 2^ in head; pectorals long, reaching to anal spines, about 2 in body, 

 ventrals moderate, 44 to 4*- in length of body, not nearly reaching vent. 

 Olivaceous, silvery below, the upper parts with golden longitudinal stripes 

 alternating with bluish interspaces; a black humeral spot larger than 

 eye. West Indies; north to Key West, south -to Rio Janeiro, very common 

 about Key West and Havana; recorded by Gronow from South Carolina, 

 but not seen by us from localities north of the Florida Keys, (unimacu-
