Cynoscion nobilis (Ayres): Fitch and Lavenberg 1971:120. 
Atractoscion nobilis (Ayres): Eschmeyer and Herald 1983:219. 
Type Specimen : Extant, Johnius nobilis Ayres 1860, no types known (Eschmeyer 1998:1193). 
Type Locality : San Francisco Bay, California. 
Referred Specimens in Fitch and Lavenberg (1971:120) : Fossil otoliths of C. nobilis have been found in a 
Pliocene exposure, San Diego, California (presumably LACMIP locality 305 [= LACM locality 44213], 
San Diego, San Diego Formation, Late Pliocene, San Diego County). No other information given. 
Remarks : The references of Miller and Lea (1972) and Eschmeyer and Herald (1983) are included to show the 
change in generic name. 
Family floscionidae David 1943 
Genus f Ioscion Jordan 1921a 
f Ioscion morgani Jordan 1921a 
Selected Synonymy & References 
f Ioscion morgani Jordan 1921a:283, pis. 8a, 49a (restoration), 
f Ioscion morgani Jordan: David 1943:149-150, text-fig. 31. 
Type Specimen : f Ioscion morgani Jordan 1921a, holotype, SU 541 (175), left headless counterpart, wherea¬ 
bouts unknown. Otolithidae. 
Type Locality : Lompoc, Monterey Formation, Late Miocene, Santa Barbara County. 
Referred Specimens : None. 
Referred Specimens in David 1943 : Only the holotype is examined. Ioscionidae. 
Remarks : David (1943:150) noted that the specimen is difficult to classify. It differs morphologically from any 
living family, but it is probably related to the carangid-like fishes. 
Family Embiotocidae 
Genus Amphistichus Agassiz 1854 
Amphistichus argenteus Agassiz 1854 
Type Specimen : Extant, Amphistichus argenteus Agassiz, no type known (Eschmeyer 1998:132). 
Type Locality : San Francisco, California. 
Referred Specimens in Fitch and Lavenberg (1971:65) : No specific specimens, however they note otoliths of 
A. argenteus have been identified from Pliocene deposits near San Diego (presumably LACMIP locality 
305 [= LACM locality 44213], San Diego, San Diego Formation, Late Pliocene, San Diego County) and 
San Pedro, California (presumably LACMIP locality 435 [=LACM locality 3065, 3759], Miraleste 
Canyon, Lomita Marl Formation, Pleistocene [Irvingtonian], Los Angeles County) (see Remarks). 
Remarks : LACMIP locality 435 (Lomita Marl), a locality Fitch and Lavenberg (1971) believed was of Pliocene 
age, is now considered Pleistocene (Blake 1991; Dibblee 1999).
