988 MESSRS, SCLATER AND SAIA'IN ON PERUVIAN BIRDS. [DcC. 12, 



35. Petasophora ioi.ata, Gould, Mon. iv. t. 226. 



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



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, ap|)arently 

 a young female of this species. 



-/ 38. Cathartes aura. 

 Arequipa, one skin. " Eyes white." 



39. MiLVAGO MEGALOPTERUS, McyCU. 



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

 D'Orbigny's figure and description of Phalcob<enus montanus. We 

 have compared them with Chilian specimens alluded to by Sclater 

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

 of distinction given by Von Pelzeln between his ])roposed new spe- 

 cies M. crassirostris and 31. montanus are very slight, and they do 

 not appear to hold good with our s])ecimens. 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. c?-assirostns.'" 



40. BUTEO ERYTHRONOTUS (King). 



One skin in the immature plumage, called by Gould Buteo vnr'ms, 

 from Arequipa. " Female, eyes white." 



-f-41. Hypotriorchis femoralis (Temm.). 

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



42. TiNNUNCULUs spARVERius (Linn.). 



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

 on the crown. " Eyes chocolate-colour." 



43. Circus poliopterus, Tsch.F. V.Aves, p. 113, t. 3; Schlegely 

 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 6'. megaspiliis, Gould, may be the young of this species ; 

 but by a recent inspection of the type sjiecimen in the British Mu- 

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

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

 dress of the C. macroptems. 



44. Strix perlata, Vieill. 



Arequipa. " Eyes dark hszel, nearly black."
