988 MESSRS. SCLATER AND SALVTN ON PERUVIAN BIRDS. [DeC. 12, 



35. Petasophora iolata, Gould, Mon. iv. t. 226. 



A young bird, probably referable to this species, from Areqiiipa. 



36. Patagona gigas (Vieill.) ; Gould, Mon. iv. t. 232. 

 Three skins from Arequipa. 



37. CoNURUs AURiFRONS (Less.). 



One example from Chihuata, of a nearly uniform green, a])parently 

 a young female of this species. 



38. CaTHARTES AURA. 



Arequipa, one skin. " Eyes white." 



39. MiLVAGO MEGALOPTERUs, Mcycn. 



Adult and young bird in change, of this species, agreeing well with 

 D'Orbigny's figure and descrij)tion of Phalcobcenus montanus. We 

 have com])ared them with Chilian specimens alluded to by Sclater 

 (aiitea, p. 329), and cannot distinguish them in any way. The points 

 of distinction given by Von Pelzeln between his proposed new spe- 

 cies M. erassirostris and M. montanus are very slight, and they do 

 not appear to hold good with our specimens. For example, in Mr. 

 Whitely's adult specimen the first primary is decidedly shorter 

 than the sixth. This is given by Von Pelzeln as a distinguishing 

 characteristic of the Chilian " M. erassirostris." 



40. BUTEO ERYTHRONOTUS (King). 



One skin in the immature plumage, called by Gould Buteo varius, 

 from Arequipa. " Female, eyes white." 



41. Hypotriorchis femoralis (Temm.). 

 Arequipa, a single female. " Eyes dark hazel." 



42. TiNNUNCULUS SPARVERIUS (LiuH.). 



Arequipa, one skin belonging to the variety without the red patch 

 on the crown. "Eyes chocolate-colour." 



43. Circus poliopterus, Tsch.F. P.^»e«, p.ll3, t. 3; Schlegel, 

 Mus. d. P.-B. Circi, p. 6. 



A single skin of an adult female. " Eyes bright yellow." Ob- 

 tained near Arequipa. Schlegel (Mus. de P.-B. Circi, p. 6) sug- 

 gests that C. met/asjiihis, Gould, may be the young of this species ; 

 but by a recent inspection of the type sj)ecimen in the British Mu- 

 seum we have ascertained that such is not the case, and that C. nie- 

 gaspilus is a long-winged bird, probably referable to the young 

 dress of the C. mucropterus. 



44. Strix perlata, Vieill. 



Arequipa. "Eyes dark hazel, nearly black."
