The ethmo-palatine cartilage (EPC) is a distinct body situated between the posterior surface of the upper arm of the premaxilla and the anterior margin of the palatine. There is usually only a single cartilage mass lying between these bones, although that cartilage is apparently subdivided into two units in some taxa (e.g., the Old World characiform family Citharinidae, Vari, 1979:294).
