[47] REVIEW OF THE SCIEZNIDS. 389 
There is no doubt of the identity of Corvina acutirostris with Baird- 
iella armata, the type of the latter having been examined by Dr. Gil- 
bert. 
Bairdiella armata is close to B. ronchus, and the character of the den- 
tition of the lower jaw, which we have used to divide Bairdiella into 
minor groups, becomes here of slight importance. 
We have examined specimens of this species from Panama, Rio Mag- 
dalena, San Matheo, Camaru, Cannarivieras, Curuga, Bahia, Pernam- 
buco, Maranhao, and [tabapuana. The specimen from the latter lo- 
cality (10837, M. ©. Z.) is nearly a foot long, and has the spines a little 
shorter and stouter than in Panama examples. 
46. BAIRDIELLA ALUTA. 
Sciena aluta Jordan & Gilbert, Proc. U. S. Nat. Mus., 1881, 232 (La Union, San Sals 
vador. 
Habitat.—Pacific coast of Central America. 
This species is known only from the original type collected by Captain 
Nichols at La Union. 
This specimen strongly resembles Bairdiella chrysoleuca, apparently 
differing only in the larger scales, fewer dorsal rays, longer caudal fin, 
and larger eyes. The two characters last mentioned may be due to 
youth, the type of aluta being smaller than any chrysoleuca examined | 
by us. The other characters are possibly results of extreme variation. 
It is, therefore, probable that the two nominal species will prove to be 
identical. 
47. BAIRDIELLA CHRYSOLEBUCA. 
Corvina chrysoleuca Giinther, Fish. Central America, 387 and 427, plate 67, fig. 1, 1869 
(Panama). 
Sciena chrysoleuca Jordan & Gilbert, Bull. U.S. Fish. Com., 1881, 316 (Panama). 
? Sciena aluta Jordan & Gilbert, Proc. U.S. Nat. Mus., 1881, 232 (La Union). 
Habitat.—Pacific coast of tropical America. 
_ A few specimens of this species were obtained at Panama by Profes- 
sor Gilbert. Two others are in the museum at Cambridge (No. 10826, 
from Panama). The species is quite variable, especially in the arma- 
ture of its preopercle. 
This species, although technically a Bairdiella, shows numerous affini- 
ties with Sciwna sciera and other species of Ophioscion. It marks the 
transition from one group of Sciznoids to the other, from those related 
to Larimus to those allied to Sciena, Pogonias, and Eques.
