 PrisHpovia humile, Kner &• Steindachner, Sitsgber. Akad. Wiss. Miincb. 1SC3, 222, 



Rio Bayano, near Panama ; name preoccupied by Pristipoiita hiimilis, BowDicn,

 Poviadasis humilis, Jordan & Fesler, I. c, 492. 



■ Tbis species is erroneously referred by Jordan & Fesler to the subgenus Pseudopris- 

 tipoma, Sauvage (Bull. Soc. Pbilom., IV, 220, 1880), of whicb tbe type is Pristipoma leu- 

 curiim, Cuvier & Valenciennes, from the Seychelles. Pseudopriitipoma seems to be a 

 vahd genus, closely allied to Amsvtremus, with which it agrees in form, but witli tlie 

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