✦ Synopsis

Letters to the Editor organic matter of coal. I. E. Valtz has not given any special name to the described maceral.

For the purpose of unifying the nomenclature E. S. Korzhenevskaya and A. V. Lapo' suggested that the term 'opaquoide' should be replaced by 'opaquoidinite' and distinguished two new individual macerals: fi-opaquoidinite (see ref. 7, figure 6) and h-opaquoidinite (see ref. 7, Figure 7). Later these macerals were assigned to the micrinite grou pa. Another 'secondary' maceral, namely p-opaquoidinite, was described (see ref. 8, Table II, Figure 5; Table VII, Figure 14; Table XIII, Figure 3) which corresponds partly to exudatinite or 'secondary' resinite according to Teichmiiller'-29-".
