white patch and generally darker colors. This new race may be char- 
acterized as follows: 
PERISOREUS CANADENSIS FUMIFRONS, Ridgw. 
Cu.—Similar to canadensis proper, but colors darker and more dingy throughout, 
and the white of the forehead obscured, or even sometimes almost wholly obliterated, 
by a wash of smoky gray or brown. 
Hab.—Coast of Alaska. rig

265. CAPRIMULGUS vociferus, Wils.—I can see no reason whatever 
for removing this bird from the genus Caprimulgus. The type of 
“* Antrostomus” is the C. carolinensis, Gmel., which differs from all the 
other Caprimulgi (so far as I am aware) in possessing fine lateral fila- 
ments to the rictal bristles, so that, in case this character be deemed 
sufficient, the genus Antrostomus may stand, if restricted to the single 
species possessing this feature. (Cf. Proc. U. S. Nat. Mus., I, pp. 142, 
143, pls. i, il.) 
266. PHALANOPTILUS nuttalli (Aud.) Ridgw.—This species is de- 
cidedly peculiar in the combination of its salient points of structure, 
having a lengthened, naked tarsus, like Nyctidromus, a character- 
istically velvety plumage, short, even tail, and unique wing-formula ; 
features which, taken together, render it a very well-marked genus, 
which may be characterized as follows :— 
PHALENOPTILUS, gen. noy. 
Cu.—Differing from Caprimulgus and ‘‘ Antrostomus” in the short, even tail (much 
shorter than the wing), and lengthened, perfectly naked tarsus (longer than the mid- 
dle toe), the first quill shorter than the fourth, and the plumage with a peculiar, 
velvety, moth-like surface. 
Type, Caprimulgus nuttalli, Aud. 
As stated on pages 142, 143, Proceedings of the United States National 
Museum, Vol. I (1878), the characters supposed to separate the Amer- 
ican Antrostomi from the Old World species of Caprimulgus, particularly 
the type of the latter genus (C. europeus, L.), are wholly intangible, 
with the exception of A. carolinensis, which has minute lateral filaments 
to the rictal bristles, these being in all other species perfectly smooth, 
or simple. On the other hand, the Caprimulgus nuttalli of Audubon 
has so many decided peculiarities of structure that it is somewhat a 
matter of surprise that its place in the genus “ Antrostomus” has not 
been questioned ere this. In fact, P. nuttalli is quite as distinct in its 
external structure from “ A.” vociferus and its allies as is the Nyctidro- 
mus albicollis. The more prominent differences of structure in these 
forms may readily be seen by comparison of the birds themselves, or by 
examination of the outline drawings of plates I and II of the volume 
of the “‘ Proceedings” referred to above. 
268. Chordeiles ACUTIPENNIS texensis (Lawr.) B. B. & R.—The Chor- 
deiles texensis of Lawrence is merely a slightly different northern form
