A new species, Bochianites (?) ambiguus sp. nov., is described from the Lower Berriasian of the Eastern Crimea. It is proposed that the name B. laevis Liu, 1988 be used instead of B. levis Arkadiev, 2008, as the former is a senior synonym and homonym. For the first time a species of the genus Leptoceras is described from the Upper Berriasian-Lower Valanginian of the former Soviet Union. Problems in the identification of heteromorph ammonites when they are partially preserved are discussed, and the geographical distribution and facial affinities of the heteromorph ammonite family Bochianitidae are considered.
