376 REPORT OF COMMISSIONER OF FISH AND FISHERIES. [34] 
_ We have not been able to compare directly Atlantic and Pacific ex- 
amples of this species, so that ws cannot be quite sure as to their iden- 
tity. The specimen now before us from Jamaica has the dark streaks 
on the scales much less sharply defined than Mazatlan examples, but 
we have no other evidence of difference. Specimens entirely similar to 
this are in the museum at Cambridge from Brazil, Porto Rico, and from 
Jérémie, Hayti. 
30. LARIMUS STAHLI. 
Monosira stahli Poey, Fauna Puerto-Riquefia, 326, plate vi, 1881 (Porto Rico), 
Habitat—West Indian Fauna, Porto Rico. 
This species is known from Poey’s description and figure only. The 
nominal genus, Monosira, supposed to be distinguished by the uniserial 
teeth, is strictly synonymous with Larimus, and the species is evidently 
very close to Larimus breviceps. 
A specimer of Larimus in the museum at Cambridge (Panama, Dr. 
Jones) agrees better with J. stahli than with L. breviceps. It has the 
mouth less oblique than in the latter, and but 24 soft rays in the dorsal 
fin. . 
381. LARIMUS FASCIATUS. 
Larimus fasciatus Holbrook, Ichthyology 8S. Carolina, 153, plate 22, fig. 1, 1860 
(Charleston). Giinther, Cat. Fish. Brit. Mus., ii, 269, 1860 (copied). Uhler & 
Lugger, Fishes of Maryland, 102, 1876. Jordan & Gilbert, Proc. U. 8S. Nat. 
Mus., 1882, 606 (Charleston). Jordan & Gilbert, Syn. Fish. North Am., 578, 
1883. 
Habitat—South Atlantic coast of the United States. 
Our specimens of this species were procured at Charleston by Mr. 
Charles C. Leslie. Specimens are in the museum at Cambridge, from 
Charleston and from Florida. 
Genus VII.—ODONTOSCION. 
Odontoscion Gill, Proc. Acad. Nat. Sci. Phila., 1862, 18 (dentex). 
TYPE: Corvina dentex Cuv. & Val. 
As here understood, this genus consists of a single species, whicn 
may be described as a Larimus armed with canine teeth. It also ap- 
proaches closely to Bairdiella, one of the species of which genus (Batrdi- 
ella archidium) would be placed in Odontoscion were it not for the 
plectroid spine on the preopercle. 
ANALYSIS OF SPECIES OF ODONTOSCION. 
a. Teeth in both jaws in a single series ; the two front teeth in lower jaw large canines, 
some of the teeth on the side of the lower jaw also enlarged, canine-like ; teeth of the 
upper jaw largest forward, smaller than those in the lower jaw; body oblong, com- 
pressed, the profile straight and rather steep; snout short, blunt, 4 in head; eye 
large, 5} to4in head; preopercle rounded without any distinct spines, with crenu- 
lated membranaceons margin; highest dorsal spine 2 in head ; distance from first 
anal spine to middle of base of eaudal 3} in length; distance from vent to first anal
