 Observer,' vol. x. p. 401 (1867). 



120. AsTURiNA NiTiDA (Lath.). 



One example, rather pale in colouring. North of Panama this 

 species is replaced by Asturina plagiata, Schlegel (Mus. des P.-B. 

 AsturirKB, p. 1), which has hitherto been usually miscalled A. 

 nitida*. 



4. On Peruvian Birds collected by Mr. H. Whitely. By 

 P. L. ScLATER, M.A., Ph.D., F.R.S., and Osbert Sal- 

 viN, M.A., F.L.S.— Part Il.f 



The present paper contains a list (accompanied by critical notes) 

 of the species of birds contained in Mr. Whitely's second collection. 

 This was entirely formed in the valley of the Tanibo (which flows 

 into the Pacific, about thirty miles south of the port of Islay) in the 

 months of October and November last. The collection contains 

 about 100 specimens, which are referable to 28 species. 



1. Anthus rtjfus. 



Alauda rufa, Gm. (ex PI. Enl. 738. fig. 1), 

 Anthus rufus, Baird, Rev. A. B. p. 156. 



Anthus parvus, Lawrence, Proc. Ac. Phil. 1865, p. 106; Salvin, 

 P. Z. S. 1867, p. 135. 

 Anthus chii, auct. plur. 



Specimens of this Pipit agree with a large series in Sclater's collec- 

 tion from different parts of South America, viz. Panama (M'Clean- 

 nan), Trinidad, M.exiana. (TFallace), Rio, Lima {Nation); and we are 

 inclined to agree with Professor Baird in adopting rufus, as its oldest 

 specific designation, although Burmeister has assigned that name to 

 the larger A. correndera. Salvin's specimens from Veragua are also 

 referable to the same species, which appears to be very widely distri- 

 buted. 



2. Spermophila telasco (Less.); Sclater, P. Z. S. 1867, p. 341. 



3. VoLATiNiA JACARiNA (Linn.). 



4. Xenospingus concolor. 



Sylvia concolor, Lafr. et d'Orb. Syn. Av. in Mag. de Zool. 1836, 

 p. 20; d'Orb. Voy. Ois. p. 216, t. 18. fig 1. 



Xenospingus concolor, Cab. J. f. Orn. 1867, p. 347. 



Specimens of both sexes of this remarkable bird, which we agree 

 with Dr. Cabanis in considering to be undoubtedly a Fringilline form. 

 It seems to us to be most nearly allied to Phrygilus, but to differ in
