Turdus nanus, Aud., was based upon a small specimen of the eastern 
Hermit Thrush, since Audubon distinctly says so in his account of the 
supposed species. The name nanus antedates pallasi; but the latter 
having been used, in a restricted sense, exclusively for the eastern race, 
while nanus has been almost wholly applied, of late years, to the small 
west-coast form now to be called 7. aonalaschkae, it seems best to discard 
the name nanus altogether and adopt for the eastern birds that of pallasi, 
as next in order of date. 
61. HELONAA swainsoni, Aud.—According to Agassiz, the correct 
orthography of the generic name of this Species (if to be separated 
from Helmitherus) is Helonea and not ‘* Helinaia,’ as spelled by 
Audubon. (Cf. Newton, P. Z.8., 1879, p. 552.) 
144a. Leucosticte griseinucha (Brandt) Bp.—The present indieations 
are that this form does not intergrade with L. tephrocotis, but, on the 
contrary, is a well-defined species of very constant characters confined 
strictly to that portion of the Alaskan coast west of the one hundred and 
thirty-fifth degree of west longitude. 
146a. Agiothus linaria, “var. fuscescens.”—No examples referable to 
the so-called fuscescens having ever been taken in winter, while the 
particular stage originally so named is represented by birds in highly 
intensified midsummer dress from various portions of subarctic America 
(the interior of the continent and coast of Alaska, as well as Labrador), 
the inference is natural that ‘“ fuscescens” represents simply the mid- 
summer plumage of the common species. (Cf. Coues, Birds of the 
Northwest, 1874, p. 115.) : 
146). dgiothus CANESCENS exilipes (Coues) Ridgw.—There is every 
probability that 2. canescens is a quite distinct species, since it occurs 
in almost every district inhabited by 4. linaria (especially in the Neare- 
tic Region), and cannot therefore be a geographical race of the same 
species. _d¥. canescens and AH. linaria holbolli are the large boreal races 
breeding in Greenland; 27. canescens exilipes and di. linaria proper are 
the smaller continental forms. 
159a. Passerculus ANTHINUS, Bp.—This seems to be quite distinct 
from P. sandwichensis, and probably more nearly relate1 to— 
1604. Passerculus GUTTATUS, Lawr., which proves to be very distinct 
from P. rostratus. 
165 a (Appendix). Ammodromus nigrescens, Ridgw.—As has already 
been insisted by Mr. Maynard (see Am. Sportsman, V. Jan. 16, 1875, 
p. 245), this bird is very probably distinet specifically from A. maritimus. 
169, Melospiza FASCIATA (Gm.) Scott—We can see no valid reason 
why Gmelin’s name for this species should not be used instead of Wil- 
son’s, bestowed upon it nearly a quarter of a century later. (Cf. Scott,
