Raw material from the respective mica-strips was also observed, but no diatoms were found. The observed valve morphologies of these taxa are discussed and compared with those of closely related taxa and two new combinations, Miosira horologium (Ehrenberg) comb. nov. and Aulacoseira californica (Ehrenberg) comb. nov., are suggested.
