We find indication of variability of the ratio Mg II 2934/2798 for 3C 232 and discuss the excitation mechanism of Mg II 2934. For 3C 249.1 we identified the following new lines: [Ne V] 3346, [Ne V) 3426 and He I 3884. Comments are made on continuum shapes; in both cases optical continuum variability is confirmed.
