Remarks : Hilton and Grande (2006:680, fig. 7)) made a few minor errors: specimen LACM 47036 was trans¬ 
posed incorrectly as 40736, and two specimens were given locality numbers (LACM 6688 and 7501) 
instead of specimen numbers. In addition, Hilton and Grande (2006:680) reported specimen LACM 40166 
from the Capistrano Formation and specimen LACM 65131 from the San Joaquin Formation, but the 
LACM catalogue lists them as Monterey and Tulare formations, respectively. Hilton and Grande 
(2006:672) considered the Tulare Formation to be Pleistocene, but most others [e.g., McPherson and 
Miller (1990)] consider it Plio-Pleistocene, thus we include specimens from the Tulare Formation in the 
catalogue.
