From Lompoc, Monterey Formation, Late Miocene, Santa Barbara County; LACM 17143 (this specimen 
was mentioned in the Addendum of Crane 1966). Chauliodontidae. 
Referred Specimens in Fitch and Lavenberg (1968:37) : No specific specimens or localities mentioned. They 
state u fossil remains of Chauliodus (entire skeletal imprints) are not uncommon in several Miocene 
diatomite and shale deposits in southern California. These represent an extinct species, C eximius .” 
From LACM locality 6907, Pomona 
Freeway Chalk Hill, Puente Formation, Late Miocene, Los Angeles County; no specific specimens men¬ 
tioned. 
Remarks : Crane (1966) believed that the holotype of ^Eostomias eximius Jordan and Gilbert (1925b) was lost, 
and designated specimen LACM 11044, right and left counterparts, as a neotype. The neotype locality was 
LACM 6589, Lompoc, Monterey Formation, latest Miocene, Santa Barbara County. Later the holotype 
was found. Based on an application by Lavenberg (1971), the International Commission of Zoological 
Nomenclature (1974) noted in opinion number 1031 that since the type specimen of fEostomias eximius
