'This species was named "Myrica proxima, sp. nov.," by Prof. Lesquereux, but this species is 

 preoccupied by the Mjiriia proxima of Ettingshauson (Beitrjig. z. Kennt. d. Foss. PI. Ncuseelands, 

 Denkschr. d. math, natnrwissensch. cl. d. k. Akad., Wien, vol. 52, 1887, p. 159, PI. iv. Fig. 14). It 

 therefore becomes necessary to change it, and I have called it Myrica obKqua. — F. H. K.
