Lutjanus uninotatus, Poey, Synopsis, 1868, 294; Cope, Trans. Am. Philos. Soc. 1871, 
470 (St. Martin’s). 
Habitat: Florida Keys to Aspinwall and Brazil. 
Etymology: cvvaypis, an old name of Dentex dentex, a species which 
this one was thought to resemble. 
This species is very common almost everywhere from Tampa to Brazil. 
It reaches but a small size, rarely exceeding a foot, and it inhabits 
chiefly shallow waters. It is known about the Florida Keys and Baha- 
mas as “Jane snapper,” and in Cuba as “biqaiba.” In Havana it is one 
of the most common food-fishes, in abundance not exceeded by any other 
species. Its strongly marked coloration renders its recognition from 
descriptions easy, and little doubt exists in its extensive synonymy. 
There is no doubt whatever as to the species intended by the lane 
snapper of Catesby. The name synagris of Linnzus is, therefore, with- 
out doubt the one-which should be retained for the species. 
Specimens of L. synagris are in the Museum at Cambridge, from 
Gonaives and Jérémie, Haiti, Porto Seguro, Havana, Ceara, Rio Ja- 
neiro, Maranhao, and Victoria. 
19. LUTJANUS AMBIGUUS. 
Mesoprion ambiguus Poey, Memorias Cuba, U1, 152, 1860, tab. 12, f. 4; tab. 13, f.18 
(Cuba); Poey, Synopsis, 295. 
Lutjanus ambiguus Poey, Enumeratio, 1875, 30; Jordan and Swain, 1. c. 
Habitat: Cuba. 
Ktymology: Ambiguus, uncertain. 
This species is very well distinguished from Lutjanus synagris and 
from Ocyurus chrysurus; but it presents such a singular blending of 
the characters of the two as to lend much probability to Poey’s con- 
jecture that it is a hybrid of Lutjanus synagris with Ocyurus chrysurus. 
Two specimens are known, the one sent by Poey tothe U.S. National
