33. CORVULA MACROPS. 
Corvina macrops Steindachner, Ichthyol. Beitr., iii, 24, fig. 2, 1875 (Panama). 
Sciena macrops Jordan & Gilbert, Bull. U.S. Fish. Com., 1831, 316 (copied). Jordan, 
Proc. U. S. Nat. Mus., 1885, 382 (Panama). 
Habitat.—Pacifice coast of tropical America, Panama. 
This species is apparently rareat Panama. Specimens were obtained 
there by Dr. Gilbert, but as these have been destroyed we have copied 
our diagnosis from Steindachner. We do not find the species in the 
museum at Cambridge. 
34. CORVULA SIALIS., 
Corvula sialis Jordan & Eigenmann, sp. nov. (Key West), 
Habitat.—F lorida Keys.

Nat. Mus.), was collected by Mr. Silas Stearns at Key West, Fla., in 
1880. We give here a detailed description of this specimen :
