As we have found that Mycteroperca rubra {acutirostris) has often or usually the 
anal fin augulated, as in the present species, it is probable that Dr. Steindachuer was 
correct in referring his specimens showing this character from Messina and Rio Janeiro 
to M. rubra (acutirostris) rather than to M. falcata. (See Steindachner, Ichth. Beitr., 
XII, 3, 1882, and Jordan & Swain, 1. c.) 
We have specimens of this species from Cuba and from Bahia, the Ya.Y\&ty phenax 
from Pensacola and Key W est.

A specimen in the museum at Cambridge (10011, 14 inches long), sent by Poey 
from Havana, is apparently typical of this species. 
Body rather deep and compressed; preopercle with salient angle; gill-rakers 
x+12; nostrils as in M. tigris, olfax, etc., the posterior considerably the larger, the 
two close together, and the large nostril with a sort of interior septum at its base
