484 MR. p. L. SCLATER ON THE BIRDS OF LIMA. [Apr. 5, 



of this monstrous individual with the same parts in the true female 

 wings (see Plate XLIV. fig. 1, male, Plate XLIV. fig. 4, female P. 

 polht.v) it will be sufficiently clear that it is to the latter that the 

 incipient male portion of the monster's wing is to be referred, and 

 that, had the male characters been fully developed, we should have 

 seen a specimen marked, like the female, with a row of large hastate 

 marks running across the hind wings, not, however, suffused towards 

 the base of the wing as in fig. 4, nor confined to the outer angle of 

 the wings as in figures 1 and 3, and wanting the large 4-partite 

 white patch of P. castor, of which there is no trace in Mr. Semper's 

 insect.

7. On the Birds of the Vicinity of Lima^ Peru. By P. L. 

 ScLATER, M.A., Ph.D., F.R.S. With Notes on their 

 Habits by Prof. W. Nation, of Lima, C.M.Z.S. (Part 



[Eeceived March 21, 1881.] 

 (Plate XLVI.) 



The small collection lately received from our Corresponding 

 INIember, Prof. W. Nation, of Lima, which I now exhibit, serves to 

 show us how far, as yet, from being exhausted, even in the generally 

 well-known class of Birds, are the Andes of Peru. Out of the 

 twelve species represented in the present series, two appear to be 

 new to science, and several others (e. g. Polyonymus caroli and Me- 

 tallura opaea) are of much rarity. 



Prof. Nation, who has fortunately passed with safety the ordeal 

 of the capture of Lima by the Chilian army, writes me word that 

 two friends, Mr. Dallas and Mr. Turfield, passing a holiday on the 

 Cordillera, agreed at his request to shoot such birds as they came 

 across, and to forward the same in the flesh to him in Lima. The 

 result of this plan exceeded Prof. Nation's utmost expectations; 150 

 specimens were secured, of which sixteen were new to Prof. Nation's 

 collection. 



It is a selection from the birds so obtained that I now exhibit,
