314 FISHES FROM BRAZIL JORDAN. 



CLUPEID^E. 

 6, Harengula humeralis (Cuv. & Val.)- 

 Several specimens. 



7. Opisthonema oglinum (Le Sueur). 

 Several specimens. 



STOLEPHORID^. 



8. Stolephorus browni (Gmelin). 

 Common. 



9. Lycengraulis grossidens (Cuv. & Val.). 



One specimen. This species is well described by Dr Giinther. 



SYNODONTID.E. 

 10. Synodus fcBtens (L.) 



Several specimens. Scales 59-60; anal 12. These specimens evi- 

 dently correspond to the ruber of Lacei)ede, the spmawws of Poey, and 

 the longirostris of Agassiz. They agree fnlly with Cuban specimens, 

 but the latter have more sharply defined coloration. I see no differ- 

 ence between these Brazilian specimens and Synodus foetens from South 

 Carolina. The dorsal in all has the first long ray about reaching tip of 

 last ray when depressed. The specimen of foetens measured by Pro- 

 fessor Meek had the dorsal mutilated and on this character chiefly he 

 recognizes spixianus as a distinct species. 



11. Trachinocephalus myops (Forster). 



Several specimens. Light brown ; three or more lengthwise stripes 

 of yellowish alternating with brown, the upper stripe just above lateral 

 line and edged with darker; a whitish streak along lateral line; about 

 six diffuse brown cross-blotches on side of back, these ceasing just 

 below lateral line ; a brown band along sides above uppermost yellow- 

 ish streak, the back above this mottled and cross-blotched. A large 

 black scapular blotch. Fins nearly plain. Top of head vermiculated 

 with darker. A dark brown band from eye across lower jaw. Snout 

 very short, shorter than eye ; teeth slender, smaller and closer set than 

 in Synodus. Pectoral very short, not quite 2 in head, but scarcely 

 reaching beyond front of ventrals which are very long— as long as 

 head — and reaching vent, and are also farther forward than in Synodus. 

 Anal unusually large, 1^ in head, 1^ to 1^ times dorsal, and of 15 

 rays. Dorsal also longer than usual, of about 11 rays. Anal 4f in 

 body ; (anal 7f in Sytiodus.) Vent at tip of last dorsal ray in Trachi- 

 nocephalus. It is far behind dorsal, nearer adipose fin in Synodus. 



Trachinocephalus is much stouter than Synodus, with short, blunt, 

 compressed head. In Synodus, the head is depressed, with flat tri- 

 angular snout ; smaller scales. These two groups may vary into each
