Type Specimen : fEctasis proriger Jordan and Gilbert 1919b, holotype, SU 125, nearly complete right coun¬ 
terpart (pi. 22), whereabouts unknown. Gonorhynchidae (?). 
Type Locality : 3 rd Street Tunnel, Pliocene, Los Angeles, Los Angeles County, California (see Remarks below). 
Referred Specimens : Known only by the type specimen. 
Referred Specimens in Jordan (T920b:569J : No specimens mentioned. ?Elopidae. 
Referred Specimens in Jordan H921a:242J : Only mentions the type specimen. Elopidae. 
Remarks : Jordan and Gilbert (1919b) described the type from the “Pliocene of the Los Angeles clayey shale at 
3 rd Street Tunnel” and provided no further locality information. The 3 rd Street Tunnel is located in 
downtown Los Angeles, California, in an area locally referred to as Bunker Hill. Surficial geologic 
mapping compiled by Dibblee (1989,1991) of the downtown Los Angeles area placed the locality in 
the early Pliocene, marine claystone of the Repetto Member of the Fernando Formation. 
Jordan and Gilbert (1919b) “provisionally and very doubtfully” placed their new genus }Ectasis in the 
Family Gonorhynchidae. Jordan (1921b) stated that the type “seems closely related to living Elops”.
