Tunlm nanus, And., was based upon a small specimeu of the eastern 

 Hermit Thrush, since Audubon distinctly says so in his account of the 

 supposed species. The name nmms antedates j)a77rts^; but the latter 

 havin<;- 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 foiiii now to be called T. aonalaschlcae, it seems best to discard 

 the name nanus altogether and adopt for the eastern birds that ofpallasi, 

 as next in order of date. 



<)1. HelonvEA stcainsoni., Aud. — According to Agassiz, the correct 

 orthography of the generic name of this species (if to be separated 

 from Helmitherus) is Heloncea and not '' Helmaia,^'' as spelled by 

 Audubon. [Of. Newton, P. Z. S., 1879, p. 552.) 



144 rr. Leueosficte griseinucha (Brandt) Bp.^ — The present indi«ations 

 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 jjortion of the Alaskan coast west of the one hundred and 

 thirty-fifth degree of west longitude. 



14:6a. ^giothus linaria, " var. /wscescews." — 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.) 



1466. ^giothus canescens exilipes (Coues) Ridgw. — There is every 

 probability that ^. canescens is a quite distinct species, since it occurs 

 in almost every district inhabited by JE7. linaria (especially in the Nearc- 

 tic Region), and cannot therefore be a geographical race of the same 

 species. ^. canescens and ^. linaria holbolli are the large boreal races 

 breeding in Greenland ; ^. canescens exilipes and JEJ. linaria proper are 

 the smaller continental forms. 



159 «. Passerculus anthinus, Bp. — This seems to be quite distinct 

 from P. sandwicheusisj and probably more nearly related to — 



160«. Passerculus guttatus, Lawr., which proves to be very distinct 

 from P. rostratus. 



165 a (Appendix). Ammodromus iiigrescens, Ridgw. — As has already 

 been insisted by Mr. Maynard (see Am. Sportsman, V. Jan. 16, 1875, 

 p. 248), this bird is very probably distinct 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,
