We are not certain whether this species really belongs to Poma- 

 centrus. Tschudi does not say anything about the denticulations of 

 the praeorbital and prseopercidum ; the vertical fins are scaly .^ We 

 are not aware whether, or where, the typical specimens, which were 

 nine inches long, are preserved.
