[100] 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.
[101] This confounding of the two sexes has probably resulted from guess-work of the collector, who, noticing the marked difference between the male and female, and naturally supposing the former to be the more brightly colored, marked the rufous-breasted specimens accordingly; while the few marked correctly may have been thus labelled after careful dissection.

[105] The females differ simply in having the light tail-space much reduced in size, and dull ochraceous, instead of whitish; in that of carolinensis it is wanting altogether.
