Referred Specimens of fX. urex in Grande 0985:2511 : From type locality: 30 specimens (AMNH 11208) and 
the holotype. 
Referred Specimens of fX urex in Brace-Thompson ( 1994:68-72. unnumbered fig.) : From type locality: men¬ 
tions several specimens and figures the right counterpart of one. 
Referred Specimens of fX. urex in Frickhinger ( 19951 : He figured one specimen housed in the FMNH. There 
was no museum number and the locality was given only as Miocene of Lompoc. 
Referred Specimens in Huddleston and Takeuchi (2006:table lk From LACM locality 6907, Pomona Freeway 
Chalk Hill, Puente Formation, Late Miocene, Los Angeles County; no specific specimens. 
Remarks : Jordan and Gilbert (1919) list SU 108 as the holotype from Lompoc, however the figure legend for 
plate 10, fig. 1 states that the specimen SU 18 is from Bairdstown (= El Sereno neighborhood of east Los 
Angeles), yet nowhere in the description is SU 18 mentioned. It is possible that SU 18 is mislabeled and 
is really SU 108, the holotype from Lompoc. Jordan and Gilbert (1920:9) noted that the original descrip¬ 
tion of fX grex in Jordan and Gilbert (1919:25) mistakenly gave the locality as Bairdstown when it should 
have been Lompoc. Grande (1985:323) noted that David (1943:90) suggested that all specimens of 
t Xyrinius probably belong to fX grex. Because this was not a positive decision, we recognize the genus 
t Xyrinius (see listings below). The LACM database lists specimen LACM 1192 as Lompoquia and gives 
no locality data for specimen LACM (CIT) 10262.
