Page 965. nhomhus, Palometa, and Poronotns should probably stand as 

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

 stand as follows : 



1363. RHOMBUS PARU (Linntens). 



1364. RHOMBUS XANTHUBCS (Qnoy & Gaimard). 



1365. PALOMETA PALOMETA (Jordan &Bollman). 



1366. PALOMETA MEDIA (Peters). 



1367. PALOMETA SIMILLIMA (Ayres). 



1368. POROXOTUS TRIACANTHUS (Peck). 



The identity of the South Atlantic Coast Rhombus nlepidotus with the 

 West Indian Bhomhus paru is very doubtful. 



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

 Icosteida'. 



Family CXXXVI(a). ACROTID^. 



Two additional specimens of Acroius willoughhyi have lately come to 

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



After Acroius wiUomjhhiji insert:
