Cache Formation, Plio-Pleistocene, Lake County; USNM 264246, two scales and one pharyngeal

Genus Rhacochilus 
Rhacochilus vacca (Girard 1855) 
Selected Synonymy & References 
Damalichthys vacca Girard 1855:320. 
Rhacochilus vacca (Girard): Fitch 1967:13. 
Rhacochilus vacca (Girard): Nolf 1985:90. 
Type Specimen : Extant, Damalichthys vacca Girard 1855, syntype, USNM 548 (Eschmeyer 1998:1733). 
Type Locality : Fort Steilacoom, Puget Sound, Washington. 
Referred Specimens in Fitch 0967:131 : No specific specimens. He mentions that remains of R. vacca , mostly 
otoliths and pharyngeal teeth, have been found in several southern California Pliocene and Pleistocene 
deposits (see Remarks). 
Referred Specimens in Nolf ( 1985:901 : He cites Fitch (1967) that otoliths of R. vacca have been reported from 
the California Pliocene (see Remarks). 
Remarks : Because no specific locality was given, the presence of R. vacca in the Neogene of California is 
questionable. 
Family Embiotocidae genus and species undetermined 
Referred Specimens in Fitch and Reimer 0967:79. 84. 86. table U : From LACMIP locality 423 (= LACM 
locality 3245), Signal Hill (= Interstate 405 and Cherry Avenue, Long Beach), Fernando Formation, Plio- 
Pleistocene, Los Angeles County; 2 otoliths (unfigured). 
Remarks : According to Powell (1998:70-71), LACMIP locality 423 (= LACM locality 3245) is in Pleistocene 
strata, therefore a Pliocene record of Embiotocidae genus and species undetermined from this locality is 
questionable. 
Family Labridae 
Genus Halichoeres Riippell 1835 
Halichoeres semicinctus (Ayres 1859) 
Type Specimen : Extant, Julius semicinctus Ayres 1859, holotype lost (Eschmeyer 1998:1535). 
Type Locality : Cedros Island, Baja California, Mexico. 
Referred Specimens in Fitch and Lavenberg 0975:781 : They state that there is an imprint of bony remains of 
a fossil labrid from the Miocene Altimira shale in Palos Verdes, Los Angeles County, however it may not 
be from H. semicinctus.
