Note 94 — BULLETIN OF THE NUTTALL ORNITHOLOGICAL CLUB. VOL. VII. October, 1882. No. 4.
Reading edition
The question of the relationship which M. cooperi, M. erythrocercus, M. mexicanus and M. crinitus bear to one another, and that of the respective names which should be used for each, has been recently discussed at some length. (See Bull. U. S. Geolog. Surv., Vol. IV, pp. 32–33; ibid., Vol. V, No. 3, pp. 402–404; Proc. U. S. Nat. Mus., Vol. 1, p. 139; and ibid., Vol. 3, pp. 13–15.) While I cannot claim to have personally investigated the points at issue, I am at present inclined to follow Mr. Ridgway’s ruling, at least so far as M. cooperi is concerned.
