37G 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 we cannot be quite sure as to their iden- 

 tity. The specimen now before us from Jamaica has the dark streaks 

 on tbe 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 

 J6r6mie, Hayti. 



30. LARIMUS STAHLI. 



Monosira stahli Poey, Fauna Puerto-Riquefta, 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 specimen of Larimus in the museum at Cambridge (Panama, Dr. 

 Jones) agrees better with L. stahli than with L. breviceps. It has the 

 mouth less oblique than in the latter, and but 24 soft rays in the dorsal 

 fin. 



31. LARIMUS FASCIATUS. 



Larimus fasciatus Hoibrook, Ichthyology S. Carolina, 153, plato 22, lig. 1, 1860 

 (Charleston). Giinther, Cat. Fish. Brit. Mus. , ii, 269, 1860 (copied). Uhler & 

 Lugger, Fishes of Maryland, 102, 1876. Jordan & Gilbert, Proc. U. S. 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 VIL— ODONTOSCIOK 



Odontosciou Gill, Proc. Acad. Nat. Sci. Phila., 1862, 18 (dentex). 



Type: Corvina dentex Cuv. & Yal. 



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 (Bairdi- 

 ella archidium) would be placed in Odontoscion were it not for the 

 piectroid 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 tbe 

 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, 3§ to 4 in bead ; preopercle rounded without any distinct spines, with crenu- 

 lated membranaceous margin ; highest dorsal spine 2 in head; distance from first
