Note 100 — Family TYRANNIDÆ.—Tyrant Flycatchers. (continued 3)
Reading edition
Pyrocephalus rubineus, var. nanus, Gould, Zoöl. Beag. iii, 45, pl. vii.—Sclater, P. Z. S. 1859, 46, 144; 1860, 282, 295; Catal. Am. B. 1862, p. 228. The last is hardly separable by the characters given, as, although they are never seen in southern specimens, they are not constant in the northern ones. Specimens of nanus are as large as any of rubineus, there being in every region a great range of variation in dimensions.
