[47] REVIEW OV THE SCI,EXII : 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. ronckus, 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, Oannarivieras, Curuca, Bahia, Pernam- 

 buco, Maranhao, and Itabapuana. The specimen from the latter lo- 

 cality (10837, M. C. Z.) is nearly a foot long, and has the spines a little 

 shorter and stouter than in Panama examples. 



46. BAIRDIELLA ALUTA. 



Sciwna aluta Jordan & Gilbert, Proc. U. S. Nat. Mus., 1831, 232 (La Uuion, San Sal- 

 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 tban 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 CHRYSOLEUCA.

 fScicena 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. 10S2G, 

 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 sclera and other species of Ophioscion. It marks the 

 transition from one group of Scisenoids to the other, from those related 

 to Larimus to those allied to Sciwna, Pogonias, and JEques.
