 rakers small and slender; barbels well developed, about as in the other 

 species; eye 4f in head; mouth larger and more oblique than in the other 

 species; the maxillary 3A- in head ; pectoral 1£ in head; longest dorsal spine 

 2 ; second anal spine 3f. Color soiled, hardly silvery ; about eight short, 

 rather faint, dark cross-bands, as wide as the interspaces ; fins all dusky. Head

79. POLYCIRRHUS DUMERILI. 



Poh/oirrhua dumerili Bocourt, Nouv. Arch. Mus. d'Hist. Natur., iv, 22, 1868 (La Union). 

 Jordan, Proc. Acad. Nat. Sci. Phila., 1883, 288 (La Union) (note on Bo- 

 court's type). 



Genyonemus fasciatus Steindachner, Ichthyol. Beitr.,ii, 31, 1875 (Panama). Jordan & 

 Gilbert, Bull. U. S. Fish Com., 1882, 111 (Panama). 



Habitat. — Pacific coast of Central America ; Panama. 



This small species is rather abundant about Panama. An examina- 

 tion of Bocourt's type of Polycirrhus dumerili has shown its identity 

 with the Genyonemus fasciatus of Steindachner. The specimens in the 

 museum at Cambridge are from Panama. 



80. POLYCIRRHUS BRASILIENSIS. 



Genyonemus brasiliensis Steiudachner, Ichthyol. Beitr., ii, 34, 1875 (Pant, Santos). 

 Micropogon ornatus Giinther, Shore Fishes Challenger, 13, plate vii, fig. A, 1880 (mouth 

 of Rio de la Plata). 



Habitat. — Coast of Brazil. 



The specimens of this species in the Museum of Comparative Zoology 

 are from Bio Janeiro and Santos. The identity of ornatus with brasili- 

 ensis has been claimed by Dr. Steindachner. Giinther's description does 

 not agree very well with the specimens examined by us, which are a 

 part of the number of Dr. Steindachner's original types. It is not 

 likely, however, that they belong to a different species. 



81. POLYCIRRHUS PERUANUS. 



Genyonemus peruan us Steindachner, Ichthyol. Beitrage, ii, 27, 1879 (Callao ; Payta). 



Habitat. — Coast of Peru. 



The specimens of this species in the museum at Cambridge are from 

 Callao and Payta. They are among the original types of Dr. Steindach- 

 ner. 



Genus XVIII.— GENYOKEMUS. 



Genyonemus Gill, Proc. Acad. Nat. Sci. Phila., 1861, 87 (lineatus). 



Type : Leiostomus lineatus Ay res. 



This genus contains but a single species, abundant along the coast of 

 California. 



Although in a general way allied to Polycirrhus and Micropogon, it has 

 some points of resemblance to Gorvula and Bairdiella, and especially to 

 Sciama deliciosa.
