816 APPENDIX C. — BIRDS. 



5. Parus septentrionalis, Harris. — Black-head Titmouse. 



Parus septentrionalis, Harris. Proceed. Acad. Nat. Sc. PMl. II. 300 (Dec. 1845). 



A single individual of this rare species was procured by Cap- 

 tain Stansburj. This bird was first described by Edward Harris, 

 Esq., from a specimen shot on the Yellow Stone Kiver in July, 

 1843, and is the largest of the American species of true Black-cap 

 Titmice, three in number. It is not improbable that two species 

 may be confounded under the name of septentrionalis^ as this spe- 

 cimen is quite different from one collected by B. H. Kern, in 

 New Mexico. The latter is, however, too much mutilated and 

 faded to serve as a proper standard of comparison, for which we 

 must wait to get better specimens. 



6. SturjSTELLA neglecta, Audubon. — Western Lark. 



Sturnella neglecta, Aud. Biog. 2d ed. VII. 340 (1843). 



The distinctions between the old Sturnella ludoviciana and the 

 present species are quite obscure. A specimen from Fort Union, 

 presented to us by Mr. Audubon, agrees with the published cha- 

 racters in nothing but the bands on the middle tail-feathers, which 

 replace the scolloping seen in S. ludoviciana. The tail is quite as 

 much rounded, and the bill of the same size. The Salt Lake bird 

 has the tail more square, and the bands on the middle tail-feathers 

 still more distinct than in the one from Eort Union. The size is 

 fully as large as that of the common species. The specimen was 

 shot March 18, 1850, in the canons between Salt Lake City and 

 the Hot Springs. This lark utters a single rough note like that 

 of the European starling.

7. NiPHOEA OREGONA, Audubon. — Oregon Snowbird. 



Fringilla oregona, Towns. Joiirn. Acad. Nat. Sc. Phil. VII. 188 (1837). — Aud. 

 Biog. V. 68, pi. 298, fig. 3, 4. 



Fringilla hudsonica, Var. Licht. Abh. Ac. Wiss. Berl. for 1838, 424. 



Fringilla nortonensis, Gm. I. 922, 87. 



This interesting species, so similar to W. hyemalis, or common 

 snowbird of the Atlantic region, replaces it in the Pacific. It
