IV, xxxv, 1, are wrong. Instead of them should be inserted F. penn- 
sylvanicus, Wils. VI, pl. liv, f. 1; —#. velox (Slate-coloured Hawk), 
Wils. VI, pl. xlvi, f. 1;—. dubius, Gm. These three birds are con- 
sidered (Syn. Am. Birds of Ch. Bonap.) as the same, and as identi- 
cal with the F. fuscus of Gmel.

Add M. Sayi, Bonap. Am. Or.I, pl. ii, f. 3;—M. fusca, Gm. 
Wils. Orn. I, pl. Ixiii, f. 5; J. acadica, Gm. Wils. I, pl. xiii, f. 3.

Here should come the genus Vireo, Vieill. (Muscrcara, L., &c.).. 
These have a bill like the Muscicapa, but it is shorter, not so much 
depressed, but rather compressed; bristly at base; upper mandible 
curved at the tip; tongue bifid at the tip. The colour of all the spe- 
_ cies is olive, more or less inclining to yellow. 
WV. flavifrons, Vieill. (Wils. Il, pl. 7, f. 3, MW. sylvicola). Throat, 
breast, forehead, and circle round the eyes, yellow. 
V. solitarius, Vieill. (MM. solitaria, Wils. Il, pl. xvii, f. 6). Head, 
bluish; circle round the eyes white, breast pale ash, belly white. 
V. noveboracensis, Vieill. (M. noveboracensis, Gm., M. cantatriz, 
“Wils. Il, pl. xviii, f. 6). Spot at the base of the upper mandible, 
and circle round the eyes, yellow; eye-lids white. 
: WV. gilvus, Bonap. (Sylvia gilva, Vieill., M. melodia, Wils. V, pl. 
xlii, f. 2). A line over the eyes, and body beneath, white; eye-lids, 
brown. 
\ V. olivaceus, Vieill. (M. olivacea, L. Wils. I, pl. xti, f. 3). Crown, 
cinereous, bounded on the sides with black; line over the eyes, white; 
eye-lids, rufous. 
XVI. 
The 7. minor, Gm., is quoted in this note as a synonyme of the 
T. mustelinus, Wils., when in fact it is the solitarius, Wils., V, p. 
xliii, f. 2. The 7. mustelinus, Gm., is the 7. melodes, Wils. I, p. ii, 
f. 1. The 7. mustelinus, Wils., is the 7. Wilsoniz, Bonap. Wils. V, 
p- xliii, £3.
