ceived from Mr. Landbeck. It seems quite distinct from the 

 two pi-eceding species — though I should like to compare it with 

 S. uropygialis, which I have not yet been able to do. 



Messrs. Philippi and Landbeck have given us an excellent 

 account of its nesting and habits. 



10. SyCALIS CITRINA. 



Emberiza citrina, Natt. MS.

Hab. San Paulo {Natt.). 



This species seems to be quite distinct from any other known 

 Sycalis, having a white spot on the inner web of the two outer tail- 

 feathers. I have never been fortunate enough to come across a 

 specimen of it. It is^ perhaps, the same as Fringilla xanthorrhua 

 of Bonaparte (J. Ac. Sc. Phil. iv. p. 350 (1825), et Consp. 

 p. 521), though, as v. Pelzeln shows, Bonaparte's description 

 does not quite agree with it. But I know of no other bird to 

 which Bonaparte's description is more applicable. 



Appendix specierum dubitatarum. 



In Mr. G. R. Gray's most useful ' Hand-list of Birds ' (ii. p. 84) 

 twenty species are assigned to Sycalis. Of these I have already 

 disposed of eighteen. The remaining two are ; — 



No. 7238. — S. plumbea. Chlorospiza plumbea, Ph. and Landb. 

 (Wiegm. Arch. 1864', p. 47), which is Phrygilus unicolor (see 

 my remarks, P. Z. S. 1867, p. 322) ; and 



No. 7239. — S. ei'ytkronota. Chlorospiza erythronota, Ph. and 

 Landb. ibid. 1863, p. 121, which is in all probability also a 

 Phrygilus, but is not known to me.

In the fifth volume of Shaw's ' Naturalist's Miscellany,' an Owl 

 is described and figured as Strix albifrons, and its habitat 

 stated to be North America, particularly Canada. In 1852, 

 Dr. Hoy published, in the ' Proceedings of the Academy of Na-
