APPENDIX TO CHECK LIST. 127 



No. 135a. The C. elegans of Baird (not of Swalnson) has been re- 

 named G. ludovicianits var. robustus, a name which, however, it may 

 not be necessary to adopt. (Am. Nat., vii, 1873, 609.) 



[No. 138] ? 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. 



[138.] PYBRHULA COCCINEA, 

 var. CASSINI Bd. 

 Cassln's Bullfincb. 



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 ^giothus 

 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

 Florida, which has been distinguished (Bull. Ess. Inst., v,' 198) as

No. 170a. Mr. Ridgway has lately demonstrated to my satisfaction 

 that Peuccea cassini is a distinct species ; the bird which I called "var. 

 cassini" is a variety of cesiiijaZis which he proposes to call var. arizoruz.
