Marl, Late Pliocene, Los Angeles County; otoliths, but no specific specimens mentioned (see Remarks). 
Referred Specimens in Fitch 0968:181 : He notes that about 600 otoliths of I. burchami have been recovered 
from the Lomita Marl (see entry above and Remarks). 
Referred Specimens in Nolf 0985:781 : No specific specimens. He cites Fitch (1968) that otoliths of I. bur¬ 
chami have been found in the California Pliocene. 
Remarks : LACMIP locality 435 (Lomita Marl, Los Angeles County) is now considered Pleistocene (Blake 
1991; Dibblee 1999), therefore the record of I. burchami in the Pliocene is erroneous. 
Order Perciformes 
Family Apogonidae 
Genus Xeneretmus Gilbert in Jordan 1903 
Xeneretmus sp. 
Referred Specimens in Fitch 0968:211 : No specific specimens. He states that otoliths of Xeneretmus have 
been found in the Lomita Marl, San Pedro (presumably LACMIP locality 435 [= LACM localities 3065, 
3759], Miraleste Canyon, Lomita Marl Formation, Pleistocene, Los Angeles County). 
Remarks : LACMIP locality 435 (Lomita Marl, Los Angeles County) is now considered Pleistocene (Blake 
1991; Dibblee 1999), therefore the record of Xeneretmus sp. in the Pliocene is erroneous 
Family Gobiidae genus and species uncertain

f Gobius oblongus Steindachner 1860:565, pl.l, fig. 3. 
f Aboma antiqua Jordan and Gilbert 1919a:56, pi. 29, fig. 1. 
Type Specimen : f Gobius oblongus Steindachner 1860, holotype. Gobiidae. 
Type Locality : Hemalser Tegel, Vienna Basin, Upper Miocene, Austria. 
Remarks : Jordan and Gilbert (1919a:56, pi. 29, fig. 1) made a confusing error. According to Duncker (1923) 
and Jordan (1927a, b), they described a fossil (presumably from Bairdstown [= El Sereno neighborhood 
of east Los Angeles], Monterey Formation, Late Miocene, Los Angeles County), based on a photograph. 
They identified the fossil as a new species, f Aboma antiqua. Unfortunately the photograph was an illus¬ 
tration of a species figured and described by Steindachner (1860) from the Miocene of Austria. Jordan 
(1927a) stated that the name f Gobius oblongus was preoccupied and the species belongs to neither 
Gobius or Aboma and its relations among the Gobiidae are not clear. We make no attempt to correct the 
taxonomy, thus we place it in Gobiidae, genus and species uncertain.
