APPENDIX TO CHECK LIST. 127 
No. 135a. The C. elegans of Baird (not of Swainson) has been re- 
named C. ludovicianus var. robustus, a name which, however, it may 
not be necessary to adopt. (Am. Nat., vii, 1873, 609.) 
[No. 188]? The query indicates that the determination of specific 
validity, cited and adopted in the Key, may have been made by Dr. 
Tristram on grounds held in the Key to constitute only geographical 
varieties; so that we may revert to the view of its original describer 
as P. coccinea var. cassini Bd. 
[1388.] PYRRHULA COCCINEA, 
var. CASSINI Bd. 
Cassin’s Bullfinch. 
No. 144. The Leucosticte tephrocotis var. australis Allen, lately de- 
scribed by Mr. Ridgway (Ess. Inst. Bull., v, 197), I believe to be 
merely the midsummer plumage of the ordinary bird, as my Agiothus 
var. fuscescens probably is of A. linaria. 
No. 155. For chestnut-colored read chestnut-collared. 
‘¢ 157. Omit the query, which should have been affixed to the next 
species. 
No. 157bis. To be cancelled. See Scott, Am. Nat., vii, 1873, 564; 
Coues, ibid., p. 696. 
No. 165. There is a curious small blackish form of this species from 
Florida, which has been distinguished (Bull. Ess. Inst., v, 198) as 
1654. AMMODROMUS MARITIMUS Sw., 
var. NIGRESCENS Ridgw. 
Bushy Seaside Finch. 
No. 170a. Mr. Ridgway has lately demonstrated to my satisfaction 
that Peucea cassini is a distinct species; the bird which I called ‘‘var. 
cassint” is a variety of estivalis which he proposes to call var. arizone. 
Am. Nat., vii, 1873, 616. So the species and varieties will stand :— 
170a. PEUCZHA ASSTIVALIS (Licut.) Cas., 
var. ARIZONZ Ridg. 
Arizona Pine Fimecin. 
170bis. PHEUCAZA CASSINI (Woopu.) Bp. 
Cassin’s Pine Finch. 
No. 173. A very notable variety of Poospiza belli, from Nevada, has 
lately been characterized (Bull. Ess. Inst., v, 198). It is much larger, 
paler and grayer, with streaked interscapulars. 
173a. POOSPIZA BELLI (Cass.) Sct., 
var. NEVADENSIS Ridg. 
Nevadan Finch.
