ilal and base of pectorals but not on other fins; lateral line little curved 

 anteriorly ; scales below lateral line in oblique series. Color bluish above, 

 silvery below; about 15 narrow dark wavy bands extending from the dor- 

 sal downward and forward to below lateral line; a round black humeral 

 spot rather smaller thau eye; fins plain olivaceous, the caudal not yellow. 

 This species is one of the most common food-fishes of our Southern coast, 

 being an excellent pan fish. Notwithstandiug the numerous nominal spe- 

 cies which authors have recognized, there is no evidence whatever of the 

 existence of more thau one species of Leiosiomiis on our coasts. South 

 Atlantic and Gulf coasts of United States; Capo Cod to Texas; once 

 doubtfully recorded from Martinique.* ic,ay06i, yellow ; 6upd, tail.)

587. PACHYPOPS, Gill. 



Pachypops, Gill, Proc. Ac. Nat. Sci. Phila. 1861,87 (trifilis). 



Fresh- water Sciaenoids of Guiana and Brazil, closely allied to Ophioscion, 

 but with small barbels in a tuft at the symphysis of lower jaw; teeth 

 feeble; preorbital serrate; mouth very small, inferior; preorbital turgid 

 and caveruous, more or less translucent; first dorsal rather short, the 

 .spines feeble ; anal short, with weak spines; soft dorsal long; caudal fin 

 rhombic ; soft parts of vertical fins closely scaled. Very close to PachyurHS, 

 Agassiz, another South American fresh-water genus, from which Pacluipops 

 difters only in the presence of barbels. (Traji;?, thick; utTo, below; aj'j^',

Head 3^ ; depth 4. D. X-I, 25 to 27; A. II, 6; scales 58. Maxillary 

 scarcely reaching front of eye, its length 1 to 4^ in head ; barbels 3, miuute 

 (sometimes obsolete); .snout prominent, blunt, 2* in head; eye very large, 

 3 in head; mouth very small, overlapped by the turgid preorbital; teeth 

 small, equal; gill rakers very small; soft dorsal aud anal completely 

 scaled; pectorals lA in head; caudal rhombic, li in heail ; second anal 

 spine 2}- in head; longest dorsal spine \l. Color uniform dusky, paler 

 below ; dorsals punctate with black. Rivers aud estuaries from Guiana to 

 Uruguay; common in brackish or fresh waters. According to Dr. Berg it 

 is found in Uruguay in brackish, never in fresh waters. The specimen here
