[37] REVIEW OF THE SCLENIDJ3. '79 



33. CORVULA MACROPS. 



Corvina macrops Steindachner, Ichthyol. Beitr., iii, 24, fig. 2, 18/5 (Panama). 

 Scicma macrops Jordan & Gilbert, Bull. U. S. Fish. Com., 1881, 316 (copied). Jordan, 

 Proc. U. S. Nat. Mus., 18S5, 382 (Panama). 



Habitat. — Pacific coast of tropical America, Panama. 



This species is apparently rare at Panama. Specimens were obtained 

 there by Dr. Gilbert, but as these have been destroyed we have copied 

 our diagnosis from Steiudachner. We do not find the species in the 

 museum at Cambridge. 



34. CORVULA SIALIS. 

 Corvula sialis Jordan & Eigenmann, sp. nov. (Key West), 



Habitat. — Florida Keys. 



The only specimen of this species, as yet known (No. 20575, U. S. 

 Nat. Mus.), was collected by Mr. Silas Steams at Key West, Fla., in 

 18S0. We give here a detailed description of this specimen :
