The belemnites described here were collected by two field parties visiting southernTibet respectively in 1960 and 1961 from(1)the Lungma—Kapula area,east of Ziang-zhi and(2)Dingje and Dingri,all of which are situated southwest of Lhasa.Theyconsist of two genera and twelve species with six new species and they may be differen-tiated into two assemblages:the first assemblage of upper Oxfordian—lower Tithonianage with Belemnopsis gerardi(Oppel)as its leading species and the second of early Cre-taceous age with Hibolites subfusiformis(Raspail)as its chief element.The geologic sections which bear the belemnites are given as follows(in descendingorder)
