 Pristipoma Inniiile, KNER & STE1NDACHNER, Sitsgber. Akad. Wiss. Miinch. 1803, 222, 



Rio Bayano, near Panama ; name preoccupied by Pristipoma humilis, BOWDICH, 



Fishes of Madeira, 236, 1825. 

 Pomadasis humilis, JORDAN & FESLEK, I. c., 492. 



* This species is erroneously referred by Jordan & Fesler to the submenus Pseudopris- 

 tipoma, Sauvage (Bull. Soc. Philom., iv, 220, 1880), of which the type is Pristipoma leu- 

 cur urn, Cuvier <fc Valenciennes, from the Seychelles. Pseudopriatipoma seems to be a 

 valid genus, closely allied to Anisotrcmus, with which it agrees in form, but with the 

 teeth all small and slender, the outer not at all enlarged.
