[77] REVIEW OF THE SCI/EN1D.E. 419 



Habitat. — West Indies ami 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 

 unchdatus, 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. S. Nat. Mus., 1881, 355 (Mazatlan) ; 

 Bull. U. S. Fish Com., 1882, 107 (Mazatlan). 



Habitat. — Pacific 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 aliip'mnis Gunther, Proc. Zool. Soc, 1864, 149 (San Jose"; Panama; Chia- 

 pam ). Gunther, Fish. Central America, 387 and 425, 1869 (Chiapam ; San Jose ; 

 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 are also in 

 the museum at Cambridge. 



Genus XX.— UMBRINA. 



Scieena (part) Artedi, 1738 (includes Corvina). 



Scieena (part) Linnseus, Systema Natune, ed. x, 289, 1758 (umbra; cirrosa). 



Umbrina Cuvier, Regne Animal, ed. i, 297, 1817 (cirrosa; Scieena L. being restricted to 



Scieena umbra, a Linnaean, and Scieena aquila, a non-Linnaean species). 

 Scieena Bleeker,* Poissons de la Cote de Guiue'e, 1862,66 (cirrosa; not the earliest 



restriction to a Linmean type). 

 Umbrina Gunther, Gill, Jordan & Gilbert, and of authors generally. 



Type : Scieena cirrosa Linnseus. 



This genus contains a considerable number of species, most of them 

 being American. It agrees with Scice na in nearly all respects, except- 

 ing 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 l'espece typique du genre Scieena Art. 6tant V Umbrina cirrosa 

 CV., le nom de Scieena devra etre appliqu6 aux especes dont Cuvier a fait des Um- 

 brina, et ne pourra plus etre employe" dans le sens de Cuvier. Ni M. Gunther ni M. 

 Gill, dans leurs travaux sur les Scienoides, paraissent avoir fait attention a ce que 

 le nom g<me"rique d' Artedi est mal employe" par les auteurs modernes, et M. Gill cite 

 meme le Scieena aquila comme le type du genre." (Sleeker, 1. c.) 



In quoting Umbrina cirrosa as the type of Artedi's geunsSciwna, Bleeker means merely 

 that it is the one placed first by Artedi in the list of species.
