[73] REVIEW OF THE SCIANIDA. 415 
bb. Caudal fin slightly lunate or §-shaped ; body compressed, rather robust; head 
low, little compressed, the snout extremely short and blunt, 43 in head; gill- 
rakers small and slender; barbels well developed, about as in the other 
species; eye 43 in head; mouth larger and more oblique than in the other 
species ; the maxillary 3} in head; pectoral 14 in head; longest dorsal spine 
2; second anal spine 33. Color soiled, hardly silvery; about eight short, 
rather faint, dark cross-bands, as wide as the interspaces; finsalldusky. Head 
32 in length; depth 3%. D. X-I, 26; A. Il, 9; scales 55.......PERUANUS, 81. 
79. POLYCIRRHUS DUMERILI. 
Polyoirrhus 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 Steindachner, Ichthyol. Beitr., ii, 34, 1875 (Parad, Santos). 
BMicropogon 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 Rio 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 peruanus Steindachner, Ichthyol. Beitriige, 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.—GENYONEMUS. 
Genyonemus Gill, Proc. Acad. Nat. Sci. Phila., 1861, 87 (lineatus). 
TYPE: Leiostomus lineatus Ayres. 
This genus contains but a single species, abundant along the coast of 
California. 
Although in a general way allied to Polycirrhus and Micropogom, it has 
some points of resemblance to Corvula and Bairdiella, and especially to 
Scicena deliciosa.
