found in numerous southern California Pliocene and Pleistocene deposits, with more than 2,000 having 
been recovered from the Lomita Marl (presumably LACMIP locality 435 [= LACM localities 3065, 
3759], Miraleste Canyon, Lomita Marl Formation, Pleistocene, Los Angeles County) (see Remarks). 
Referred Specimens in Fitch and Reimer (1967) : From LACMIP locality 423 (= LACM locality 3245), Signal 
Hill (= Interstate 405 and Cherry Avenue, Long Beach), Fernando Formation, Plio-Pleistocene, Los 
Angeles County; one otolith (fig. 21) (see Remarks). Bothidae. 
Referred Specimens in Fitch f 1968:124 : Same information as in Fitch (1967) above. 
Referred Specimens in Zinsmeister 0970:124. table P : From LACMIP locality 471 (=LACM locality 3802), 
Upper Newport Bay (= Newport Back Bay Cliffs), Fernando Formation, Plio-Pleistocene, Orange County; 
no individual specimens mentioned, only the presence of the genus in the deposit. He did not distinguish 
between teeth and otoliths as remains. 
Referred Specimens in Nolf 0985:1041 : He cites Fitch (1970), a citation we can not locate, that otoliths of 
L. exilis have been reported from the Pliocene of California. 
Remarks : Locality LACMIP locality 35 (Lomita Marl) is now considered of Pleistocene age (Blake 1991; 
Dibblee 1999). According to Powell (1998:70-71), LACMIP locality 423 (= LACM locality 3245) is in 
Pleistocene strata, therefore a Pliocene record of L. exilis from this locality is questionable.

Referred Specimens in Fitch ( 1967:1 lk No specific specimens. He states that otoliths of G. zachirus are abun¬ 
dant in some California Pliocene and Pleistocene deposits, with over 700 having been recovered from the 
Lomita Marl (presumably LACMIP locality 435 [= LACM localities 3065, 3759], Miraleste Canyon, 
Lomita Marl Formation, Pleistocene, Los Angeles County) (see Remarks).
