66 REVIEW OF LAGODON, ARCHOSARGUS, AND UIPLODUS. 



1. LAGODON. 

 LaGODON Holbrook, Ichth. South Carolina, 59, 1860 (rhomboide^). 



Type. — Spams rhomhoides Liuuaeus. 



There is a marked differeuce in the character of the iuterorbital boues 

 of Lagodon as compared with Archosargus and Diplodus. As there are 

 no species known which show intermediate characters between L. rhom- 

 hoides and the species of Archosargus, the differences set forth in the key 

 may be considered of generic value. The interorbital bones of Archo- 

 sargus are much more like those of Diplodus than like those of Lagodon. 



But one species of Lagodon is yet certainly known.
