Page 965. Rhombus, Palometa, and Poronottis should probably stand as 

 distinct genera. The species placed in Rhombus in the text would then 

 stand as follows : 



1363. RHOMBUS PABU (Linnams). 



1364. RHOMBUS XANTHURUS (Quoy & Gaimard). 



1365. PALOMETA PALOMETA (Jordan &Bollman). 



1366. PALOMETA MEDIA (Peters). 



1367. PALOMETA SIMILLIMA (Ayres). 



1368. PORONOTUS TRIACANTHUS (Peck). 



The identity of the South Atlantic Coast Rhombus alepidotus with the 

 West Indian Rhombus paru is very doubtful. 



Page 973. The genus Acrotus, Bean, represents a family distinct from 

 Icosteidce. 



Family CXXXVI(a). ACROTID^E. 



Two additional specimens of Acrotus ivilloughbyi have lately come to 

 light the one from Port Townsend, the other from Monterey. 

 After Acrotus willoughbyi insert :
