[77] REVIEW OF THE SCIAZNID&. 419 
Habitat. West Indies and coasts of South America. 
This species is generally common in the West Indies and southward 
along the coast of Brazil. It is very close to the northern Micropogon 
undulatus, and for this reason its real distinction from the latter has 
been generally overlooked until quite lately. We have examined nu- 
merous specimens from Cuba and from Rio Janeiro. 
85. MICROPOGON ECTENES. 
Micropogon cctenes Jordan & Gilbert, Proc. U. 8. Nat. Mus., 1881, 355 (Mazatlan) ; 
Bull. U. S. Fish Com., 1882, 107 (Mazatlan). 
Habitat.—Pacifie coast of Mexico; Mazatlan. 
This species was found by Professor Gilbert in moderate abundance 
at Mazatlan, where it seems to take the place of the closely allied Mi- 
cropogon altipinnis. 
86. MICROPOGON ALTIPINNIS. 
Micropogon altipinnis Giinther, Proc. Zool. Soc., 1864, 149 (San José; Panama; Chia- 
: pam). Giinther, Fish. Central America, 387 and 425, 1869 (Chiapam; San José; 
Panama). Jordan & Gilbert, Bull. U.S. Fish Com., 1882, 111 (Panama). 
Habitat.— Pacific coast of Central America. 
This species is closely related to the others of the genus. It was 
found by Dr. Gilbert at Panama. Specimens from Panama aré also in 
the museum at Cambridge. 
Genus XX.—UMBRINA. 
Scizena (part) Artedi, 1738 (includes Corvina). 
Scizna (part) Linnzus, Systema Nature, ed. x, 289, 1758 (wmbra; cirrosa). 
Umbrina Cuvier, Réegne Animal, ed. i, 297, 1817 (cirrosa ; Sciena L. being restricted to 
Sciena umbra, a Linnean, and Sciwna aquila, a non-Linnzan species). 
Scicena Bleeker,* Poissons de la Céte de Guinée, 1862, 66 (cirrosa; not the earliest 
restriction to a Linnean type). 
Umbrina Giinther, Gill, Jordan & Gilbert, and of authors generally. 
TyPE: Sciena cirrosa Linneus. , 
This genus contains a consislerable number of species, most of them 
being American. It agrees with Scie na in nearly all respects, except- 
jng the presence at the chin of a short, thick barbel. A similar barbel 
is found in the genus Menticirrhus, but notwithstanding the fact that 
all European writers have confounded Menticirrhus with Umbrina, the 
two genera are not among the most closely related in this family. 

 *“Je note ici que Vespece typique du genre Sciena Art. étant V Umbrina cirrosa 
CV., le nom de Sciwna devra étre appliqué aux espéces dont Cuvier a fait des Um- 
_ brina, et ne pourra plus étre employé dans le sens de Cuvier. Ni M. Giinther ni M. 
- Gill, dans leurs travaux sur les Sciénoides, paraissent avoir fait attention 4 ce que 
le nom générique d’Artedi est mal employé par les auteurs modernes, et M, Gill cite 
méme le Sciwna aquila comme le type du genre.” (Bleeker, 1. c.) 
In quoting Umbrina cirrosa as the type of Artedi’s genus Sciwna, Bleeker means merely 
that it is the one placed first by Artedi in the list of species.
